Photosynthesis Flashcards
What is photosynthesis?
Plants make food through the process of photosynthesis. Photosynthesis is a chemical reaction in which plants take carbon dioxide and water and change them into glucose.
What is a producer?
Plants and algae are called producers because they make their own food. They convert materials in their environment and turn them into glucose.
How are plants adapted for photosynthesis?
Plants have specifically adapted to organs that allow them to obtain all the resources needed for photosynthesis. These organs are the leaves, stem and roots.
How does water get into a plant?
Water diffuses into the root hair cells. The hairs provide a large surface area to maximise diffusion of water into the plant. The water is then transported around the plant in long hollow tubes.
How do gases get into and out of a plant?
On the underside of the left there are tiny holes. These allow gases to diffuse into the leaf. Carbon dioxide diffuses into the left and oxygen diffuses out.
