Four types of seed dispersal

2 wind dispersal
3 self dispersal
4 water dispersal
Animal dispearal
Animal dispersal happen when fleshy fruits are eaten by animals or birds
Germination
Is the growth of seeds into a plant
What do seeds need
Water oxygen heat
Photosynthesis
Is the process of where green plants make food using light energy
Why are leaves and plants green
Cause they contain chlorophyll
Chlorophyll where is it found
Found in chloroplasts in plant cells
Why do plants looses leave in winter
Less sunlight and drop in temperature
Stomata
Little hole on the under side of leaves for gas exchange

From their roots
How do plants get carbon dioxide
