Prokaryotes are classified into two domains: Bacteria and Archaea. Bacteria are identified by their shape, cell wall composition, motility, and how they obtain and use energy. They reproduce asexually through binary fission. Genes can also be transferred between bacteria through conjugation, increasing genetic diversity. Prokaryotes play crucial roles in ecosystems through nutrient cycling and symbiotic relationships, but some can also harm humans.1 Curso Ingenier鱈a Celular

Prokaryotes have adapted structures that allow them to thrive in many habitats, including fimbriae, capsules, flagella, and cell walls. They reproduce quickly through binary fission and genetic recombination, allowing populations to evolve rapidly in response to environmental changes. Prokaryotes use different methods of nutrition, including photoheterotrophy, chemoautotrophy, and chemoheterotrophy. They also show metabolic adaptations for oxygen levels and nitrogen fixation. Molecular systematics is leading to a phylogenetic classification of prokaryotes, with Archaea and bacteria in their own domains based on adaptations to extreme environments.Structureofbacterialcell 180806181503

Genetic variations can occur in plants produced through plant tissue culture and be detected as changes in genetic characteristics or phenotypes. Variations commonly include changes in chromosome number and structure. Regenerated plants with chromosomal changes often show alterations in traits like leaf shape and color, growth rate, and fertility. These heritable mutations can persist when plants are transplanted to fields. Somaclonal variations are caused by genetic factors like pre-existing variations in explant cells or mutations during tissue culture, and can result in changes in plant characteristics that are useful for crop improvement.Ubaid afzal (28)

Bacteria can reproduce asexually through binary fission or sexually through conjugation. Binary fission is the process where a single bacteria cell duplicates its DNA and divides into two identical daughter cells, allowing bacteria populations to double in size very rapidly under the right conditions of warmth, moisture, food and other environmental factors. During conjugation, genetic material is exchanged between two bacteria cells through a bridge formed between their cell walls.Ubaid afzal (26)

Somaclonal variations refer to genetic or phenotypic variations that arise in plants produced through tissue culture. These variations can be heritable or non-heritable. Heritable variations are caused by pre-existing mutations in somatic cells or new mutations during tissue culture. Non-heritable variations are temporary phenotypic changes caused by epigenetic effects. Somaclonal variations can arise due to physiological, genetic, or biochemical causes like exposure to plant growth regulators, changes in chromosome number or structure, gene mutations, changes in DNA or protein levels, or alterations in metabolic pathways. While somaclonal variations can help crop improvement, selected variants may be genetically unstable and require extensive testing.Ubaid afzal (7)

Somaclones are genetically identical plants produced through tissue culture. Somaclonal variation refers to genetic or phenotypic traits that arise in somaclones due to tissue culture. Variations can occur in karyotype, isozymes, and morphology. Variations can be heritable and persist in subsequent generations. Somaclonal variations are caused by pre-existing mutations in explant cells or new mutations induced during tissue culture. They can be detected by analyzing morphological, cytological, biochemical, and molecular characteristics of regenerate plants. Somaclonal variation is useful for crop improvement but selected variants require extensive field testing due to genetic instability.Scope of Biotechnology by Rajesh sahu

Plant protoplast fusion allows for the introduction of new genes into plant species by mixing and fusing the protoplasts, or plant cells without cell walls, from different plant types. The process involves digesting the cell walls of plant cells with enzymes to create protoplasts, incubating the protoplasts in a solution with mannitol to cause plasmolysis and easier digestion of the cell wall, and placing the protoplasts in a medium that encourages cell wall growth and the fusion of protoplasts from different plant species.Ferns & fern allies

Primitive vascular plants evolved adaptations for life on land including vascular tissue for transport and alternation of generations. They include psilophytes which were the earliest vascular plants with no specialized organs, lycophytes with true roots, stems and scale-like leaves requiring water for reproduction, and sphenophytes with whorled leaves and siliceous stems requiring water for motile sperm. Advanced ferns have well-developed vascular tissue and xylem and phloem, thriving in damp habitats with a dominant sporophyte and inconspicuous gametophyte reproducing via spores in sori on fronds.Disease

A disease is defined as any change that interferes with normal body functioning. The Germ Theory of Disease states that infectious diseases are caused by specific infectious agents like viruses, bacteria, fungi, or parasites. Koch's postulates provide a method to determine if a specific pathogen causes a particular disease by finding the microorganism in diseased subjects but not healthy ones, being able to isolate and grow it in culture, and using the cultured version to reproduce the disease in a healthy subject. Diseases can spread through direct or indirect contact, fecal-oral transmission, airborne droplets, or vectors. The body defends against disease through non-specific and specific immune responses.Animal development and architecture

Bacteria and viruses share some characteristics:
- They can both reproduce rapidly and mutate. However, bacteria are cellular and prokaryotic while viruses are non-cellular and require a host cell to reproduce.
- Bacteria come in many types including autotrophs that produce their own food and heterotrophs that feed on organic material. They have cell walls and circular DNA.
- Viruses have either DNA or RNA inside a protein coat and some have an additional envelope. They reproduce by taking over the machinery of living host cells. While viruses cause disease, some bacteria are useful in food webs, nitrogen fixation, and producing antibiotics.09 bakteri dan archae (2).pptx

The first organism to evolve on Earth was probably a single-celled organism, similar to modern bacteria. Since then, life has evolved into many forms of life over many millennia. However, we can still trace our ancestors back to this single-celled organism. Today, bacteria are considered the oldest life forms on Earth.Prokaryotes

This document provides information about prokaryotes, including their defining characteristics, classification, and examples. Some key points:
- Prokaryotes are unicellular organisms that lack membrane-bound organelles and a nucleus, and were the first living organisms to evolve around 3.8 billion years ago.
- They are classified into two domains: Bacteria and Archaea. Bacteria are further classified by shape, staining, cell walls, and other traits.
- Prokaryotes can be autotrophic or heterotrophic, living in diverse environments. They play important roles in industry, the environment, and human bodies.morphphysioofbacteriadr-180131090251.pdf

This document contains questions for a student about osmoregulation - the process by which aquatic organisms regulate their internal salt concentrations. It asks about nitrogenous waste products in different organisms, and the effects of freshwater vs saltwater on fish. It also asks questions about thermoregulation in humans and how water is used to cool engines and nuclear reactors. The conclusion section is blank.Overview of excretion in mammals
Overview of excretion in mammalschuckiecalsado
油
The mammalian kidney filters blood in the glomerulus and regulates water and salt balance through selective reabsorption and secretion in the nephron's tubule segments. In the proximal tubule, most reabsorption occurs, while the thin ascending loop of Henle secretes salt and the thick ascending loop reabsorbs salt actively. The collecting duct determines salt excretion, reabsorbing water passively. Osmoreceptors detect blood osmolarity and volume changes, triggering antidiuretic hormone and the renin-angiotensin-aldosterone system respectively to regulate water and salt balance. Through selective tubule transport, the kidney maintains homeostasis.Integumentary activity

The immune system defends the body against pathogens through layered lines of defense. The innate immune system provides immediate nonspecific responses while the adaptive immune system mounts targeted responses through lymphocytes. B and T lymphocytes recognize pathogens through antigen receptors and mount humoral or cell-mediated responses involving antibody production or cytotoxic killing. Immune memory develops from these responses to provide faster protection upon reexposure. A balanced immune response is needed, as deficiencies or issues with self-tolerance can lead to infection or autoimmunity.Cell respi photosynthesis activity

The three lines of defense in the immune system are:
1) First line is external non-specific defenses like skin and mucus.
2) Second line is internal non-specific defenses like white blood cells and antimicrobial proteins.
3) Third line is internal specific defenses using B cells, T cells, and antibodies for a targeted response.Transport activity

Prokaryota
- 1. Prokaryota
- 2. Core Concepts Prokaryotes are classified into two domains/kingdoms: Bacteria and Archaea Presence of peptidogycan in bacteria Some archaea have pseudopeptidoglycan Diverse cell wall, some made up of proteins called S layer
- 3. Bacteria are identified by their shapes, the chemical natures of their cell walls, the ways they move and the ways they obtain and use energy Bacteria reproduce asexually by binary fission. Through the process of conjugation, genes can move from one cell to another, thus increasing genetic diversity within bacterial populations
- 4. Prokaryotes play a crucial role in the biosphere, such as taking part in nutrient cycles and in symbiotic relationships. Also, they have both harmful and beneficial impacts on humans
- 5. Keywords Prokaryte bacteria archaea Peptidoglycan coccus bacillus Spirillum Gram-negative Gram-positive Flagellum autotroph heterotroph Phototroph chemotroph aerobe Facultative anaerobe obligate/strict anaerobe Binary fission conjugation endospore
