|
buried forests become deposits of coal, oil, and natural gas
|
|
|
Why do plants in the phylum bryohyta have to live in moist areas
|
because they lack tissues that store and transport water

2)absorb water 3)take in minerals 4)store food |
|
|
How do leaves change color
|
They lose their chlorophyll and underlying colors start to come out
|
|
|
Write the equation for photosynthesis
|
CO2+H20+Sunlight->C6H12O6+O2+H20
|
|
|
