Photosynthesis
• Photosynthesis is the process by which plants make their food.
• Photosynthesis occurs in the leaves of a plant.
• The green chemical chlorophyll is needed for photosynthesis. It is found in the chloroplasts in a plant cell.
• Chlorophyll traps light energy and uses it to combine carbon dioxide and water. This forms glucose and oxygen.
• The water needed for photosynthesis is collected from the soil through the roots and is transported around the plant in xylem cells.
• Leaves have air spaces between their leaves called stomata. This is where the product Oxygen leaves the plant and Carbon Dioxide enters the plant.
• The three things needed for photosynthesis to occur are light, water and carbon dioxide.
• The word equation for photosynthesis is :
Carbon Dioxide + Water -----(Light & Chlorophyll)-----> Oxygen + Glucose
Tropisms
• A tropism is a growth of a plant in response to a stimulus, e.g. gravity, light.
• Geotropism is a plant's response to gravity. Geotropism causes the roots of a plant to grow downwards.
• Phototropism is a plant's response to light. Phototropism causes a plant's stem to grow towards the light.
