Creating a plant jungleThe twins, Mike and Mary, have beenreading books and watching televisionprograms about jungles. They arefascinated by all the plants and treesthat grow there and how different it isfrom their garden. I wish we lived inthe jungle, Mary said to her mum. 12. Well, mum said I dont think we cando that but we can try to make one.Thats impossible, said Mike.What do you think-is it possible? 13. The factor for plants growthWater: Water is essential because it moistures the soiland dissolves important nutrients that the plant needsin order to grow.Light: Light is a factor required in order thatphotosynthesis can occur in plants.Soil: The soil serves the needs of the plant by providingwater, air, nutrients, and stability.Temperature: Plants grow well only within a limitedtemperature range. Temperatures that are too high ortoo low will result in abnormal development andreduced production. 14. Oxygen: Plants require oxygen for respiration to carry outtheir functions of water and nutrient uptake.Carbon Dioxide: Carbon Dioxide (CO2) contributes toplant growth as part of the miracle of nature known asphotosynthesis. This enables plants to combine CarbonDioxide and water with the aid of light energy to formsugar.Mineral Nutrients: Green plants must absorb certainminerals through their roots to survive.Humidity: The relative humidity present in the air isutilized by the plants and this is a crucial factor for thetranspiration process of the plants. 15.
