Describe how a fern reproduces.
Spores release — When the spores are mature, they are released into the air.
Dispersal — The spores are very light, so they are usually carried away by the wind. Sometimes, water (like rain or streams) can also help move them.
The edge or perimeter of the leaf blade is the...
margin
___________ is a leaf with distinct, rounded or pointed projections that extend well over halfway, sometimes almost to the midrib, of the leaf's width.
How are plant and animal cells different?
Plant cells have a cell wall and chloroplasts for photosynthesis. Animal cells do not.
What do we call animals like bees that move pollen?
Pollinators.
