This document describes the main parts and functions of cells. It identifies the cell wall, cell membrane, cytoplasm, mitochondria, chloroplasts, vacuoles, nucleus, nuclear membrane, and chromosomes as the key parts of eukaryotic cells. The cell wall and membrane protect the cell, the cytoplasm allows movement within the cell, mitochondria produce energy, chloroplasts perform photosynthesis, vacuoles store materials, and the nucleus and chromosomes control cell activities. Prokaryotes are simple single cells without nuclei, while eukaryotes are complex multicellular organisms.
Cells
- 1. Parts, Functions and Kinds
- 2. Cell Wall – Fence of the Cell Cell Membrane – Gate of the Cell Cytoplasm – Area of Movement Mitochondria – Powerhouse of the Cell Chloroplasts – Food Producers Vacuoles – Storage Tanks Nucleus – Control Center Nuclear Membrane – Gate of the Nucleus Chromosome – Director of the Cell
- 3. Cell Wall - Surround and protect the cell - Makes the cell stiff and strong Cell Membrane - Hold and protect the cell - Control the movement of materials into and out the cell Cytoplasm – A gel-like material in which cell parts move Mitochondria – Produce and supply most of the energy for the cell
- 4. Chloroplasts - Captures the energy of sunlight to produce food for the plant - Contains the chlorophyll Vacuoles – Store food, water, and chemicals Nucleus – Act as the brain of the cell - Regulate and control all cell activities Nuclear Membrane – Surround and protect the nucleus Chromosome – Directs all cell activities
- 5. Prokaryote – Simple Cells - No Cell Nucleus Eukaryote – Made up of Multiple Cells
