Where is DNA stored in a Eukaryotic cell?
in the nucleus
According to cell theory, what are all living things made of?
one or more cells
Which biomolecule is responsible for many structures and functions in organisms, including enzymes and muscles?
Proteins.
What is the movement of water across a selectively permeable membrane called?
Osmosis.
What are the two main types of cells?

mitochondria
Name two organelles or structures that are present in both plant and animal cells.
the nucleus, mitochondria, cell membrane, ribosomes, cytoplasm, and endoplasmic reticulum.
A cell surrounds a large particle with its cell membrane and brings it into the cell. What process is this?
Endocytosis.
Name two structures found in plant cells that are not found in animal cells.
