cell wall
Surrounds the plant cell and helps to keep its shape.
cell membrane
Allows water and nutrients to come and and waste to go out of the cell.
nucleus
Controls the cell's grown, the "brain" that contains genetic information.
green chloroplasts
Produce food for the plant cell.
cytoplasm
The jelly-like substance that holds all cell parts in place.
animal cells
Cells that have a cell membrane, nucleus, cytoplasm, and other organelles.
plant cells
Cells that have a cell wall, cell membrane, nucleus, chloroplasts, organelles, and cytoplasm

classification
To sort animals and plants into different groups
mammals
Give birth to live babies, have fur or hair, warm-blooded
birds
lay eggs, have feathers, are warm-blooded

"higher plants," carry water from their tubes through leaves
non-vascular
"lower plants," soak water straight from the ground
