Substrand: "5.1 Plant growth" (25 periods)

Green plants use light energy and carbon dioxide to make food by the process of photosynthesis. Photosynthesis takes water and carbon dioxide to make food using the solar energy. Oxygen gas is produced as a waste in the process and released to the atmosphere. Plants absorb water and nutrients from the soil and carbon dioxide from the air. They use water to transport the nutrients and food from photosynthesis to all parts of the plant. The energy in the food is released to the plant through a process of photosynthesis. The food and nutrients cause the plant to grow. Respiration in plants releases energy for growth and movement.

Learner's should:

5.1.1 understand that the different parts of a plant have specific functions (u)

5.1.1.1 draw a diagram of a plant labeling the parts and noting their functions

5.1.2 understand that green plants need water, light energy and carbon dioxide for the process of photosynthesis. This process produces food (u)

5.1.2.1 draw a simple diagram of a green plant to illustrate the process of photosynthesis in terms of light energy, carbon dioxide and oxygen
5.1.2.2 do a simple experiment to show that plants need sunlight to grow

5.1.3 understand how nutrients from the soil are absorbed and transported to parts of the plant (u)

5.1.3.1 indicate the part of a plant stem which transport nutrients absorbed from the soil to other parts of the plant

5.1.4 understand that the green plant uses the food from photosynthesis by respiration (u)

5.1.4.1 tabulate the elements of the processes of photosynthesis and respiration in plants

5.1.5 appreciate that oxygen gas is a by-product of the process of photosynthesis; green plants give oxygen to the atmosphere (v)

5.1.5.1 state that the oxygen from the photosynthesis process is used by animals
