Cell Parts Flashcards
organelle that generate energy; the powerhouses of the cell
mitochondria
lipid barrier that surrounds the cell
Plasma or Cell Membrane
tough outer layer of plant cells that surrounds the cell membrane to provide structure and support and protects the cell
cell wall
the entire contents of the cell inside the cell membrane (the organelles and cytosol), excluding the nucleus
cytoplasm
organelle that processes and packages proteins
Golgi apparatus
membrane-bound organelle that provides storage for things like water and nutrients
vacuole
Name three distinct differences between plant cells and animal cells
1) Plant cells contain a cell wall, but animal cells do not.
2) Plant cells have a large central vacuole. The vacuoles in animal cells are much smaller.
3) Plant cells contain chloroplasts, which animal cells do not have.
organelle that breaks down and recycles old molecules
lysosomes
organelle where proteins and lipids are made
endoplasmic reticulum (ER)
organelle that carries out photosynthesis in plants
chloroplast
membrane-bound organelle that contains genetic material
nucleus
non-membrane bound organelle in which proteins are made
ribosomes
Name three parts of the cell theory
All organisms are composed of cells.
Cells are alive and the basic living units of organization in all organisms.
All cells come from other cells.
jellylike substance in which the contents of the cell are suspended
cytosol
small membrane-bound sac that transports proteins around the cell or to the cell membrane
vesicle
