General Parts of the Cell
The two types of cells are:
Prokaryotic and eukaryotic
This theory states that the early ancestor of eukaryotes engulfed an oxygen-using nonphotosynthetic prokaryote
Endosymbiont theory
Animal cells contain a cell wall: true or false
False, only plant cells contain a cell wall
Prokaryotic cells have a nucleus: true or false
False
The outer layer that maintains the cell's shape and protects the cell from mechanical damage
Cell wall
The infoldings in the inner membrane that increases surface area
Cristae
In animal cells (eukaryotic cells) DNA is found inside:
The nucleus
The boundary between the cell and the environment
Plasma membrane
Flattened interconnected sacs in the plant cell
Thylakoids
Large motor proteins that enable bending
Dyneins
A membranous sac of hydrolytic enzymes used to hydrolyze macromolecules
Lysosome
The jelly-like substance found inside the cytoplasm
Cytosol
Disc-shaped structures that contain chlorophyll
Plastids
Microfilaments are made of:
Actin- a globular protein
The two locomotor appendages found in eukarytoic cells are:
Flagella and cilia
In prokaryotic cells DNA is found in a non-membrane enclosed region called:
The nucleoid
The space outside the thylakoid in a plant cell. It contains fluid, DNA, ribosomes, and enzymes
Stroma
The region located near the nucleus where microtubules are initiated
A region of the cell that contains ribosomes on the outer surface (hint: this is one of the two distinct, connected regions continuous with the nuclear envelope)
Rough ER
