The twins Mike and Mary are fascinated by jungles after learning about them. They ask their mother if they can make a plant jungle at home. Their mother thinks it may be possible. The document then provides instructions on how to create a plant jungle by putting soil and compost in a plastic jar, planting lettuce and bean seeds, watering them, and observing their growth over weekly periods. Key factors for plant growth like water, light, soil, temperature, oxygen, carbon dioxide, and minerals are also explained.

- 12. Creating a plant jungle The twins, Mike and Mary, have been reading books and watching television programs about jungles. They are fascinated by all the plants and trees that grow there and how different it is from their garden. ‘I wish we lived in the jungle,’ Mary said to her mum.
- 13. Well,’ mum said ‘I don’t think we can do that but we can try to make one’. That’s impossible,’ said Mike. What do you think-is it possible?
- 14. The factor for plants growth Water: Water is essential because it moistures the soil and dissolves important nutrients that the plant needs in order to grow. Light: Light is a factor required in order that photosynthesis can occur in plants. Soil: The soil serves the needs of the plant by providing water, air, nutrients, and stability. Temperature: Plants grow well only within a limited temperature range. Temperatures that are too high or too low will result in abnormal development and reduced production.
- 15. Oxygen: Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. Carbon Dioxide: Carbon Dioxide (CO2) contributes to plant growth as part of the miracle of nature known as photosynthesis. This enables plants to combine Carbon Dioxide and water with the aid of light energy to form sugar. Mineral Nutrients: Green plants must absorb certain minerals through their roots to survive. Humidity: The relative humidity present in the air is utilized by the plants and this is a crucial factor for the transpiration process of the plants.
