What are the parts of a plant and animal cell?
Lysosomes, cytoplasm, ribosomes, endoplasmic reticulum, cell membrane, membrane, nucleus, vacuole, mitochondria, Golgi apparatus, organelles, cell wall, and chloroplasts.
What is found only in plant cells?
Cell wall, and chloroplasts
What is found only in animal cells?
Lysosomes.
Membrane definition
Athin barrier that keeps different parts of the cell separate from one another.
Cytoplasm definition
It fills the cell and surrounds the organelles to contain nutrients the cell needs to survive
Endoplasmic reticulum definition
A folded organelle that makes protein in the cell.
Ribosome definition
Small organelle in the cells cytoplasm that helps make protein.
Golgi apparatus definition
A folded organelle that combines protein and gives then to the rest of the cell and outside the cell.
Mitochondria definition
Organelles that break down food and releases the stored energy so the cell can use it to fuel its activities.
Whats a cell membrane
Thin covering holding the cytoplasm and organelles and controls was goes in and out of the cell
Whats an organelle
