Photosynthesis Flashcards
What is Photosynthesis
It is a process where the plant make their own food
What is Chlorophyll
A substance that makes plants green
What is Carbon Dioxide?
It is a gas in the air that plants need for photosynthesis
Describe the process of photosynthesis in a picture
- Chlorophyll in the leave absorbs sunlight
- Leaves take in carbon dioxide gas >
- Leaves make food > Glucose sugar
- Roots absorb the water

- Fruits: Apples & Banana

How do we test for starch
- Starch is made in green plants and stored in different parts of the plant
- We test for starch using a substance called iodine which is yellow in color
- Iodine changes blue-black is starch is present
Draw a diagram of the relationship between plants and animals
- Plants give off oxygen during photosynthesis
- Animals and humans breathe out carbon dioxide
- Animals and humans breathe in Oxygen
a) _______ are very important in keeping the amounts of b) __________ and c) __________in the air constant.
a) Plants are very important in keeping the amounts of b) carbon dioxide and c) oxygen in the air constant.
What is the relationship between plants and air ?
- Plants use Carbon Dioxide for Photosynthesis.
- Humans and animals breathe out carbon dioxide
- Animals and humans breathe in oxygen
