Biology and Cell Structure Flashcards

Front

Nucleus

Back

The control center of the cell, containing genetic material (DNA).

Front

Nucleolus

Back

A structure within the nucleus that produces ribosomes.

Front

Endoplasmic Reticulum (ER)

Back

A network of membranes involved in protein and lipid synthesis; rough ER has ribosomes, smooth ER does not.

Front

Ribosome

Back

A molecular machine that synthesizes proteins.

Front

Lysosome

Back

An organelle containing digestive enzymes to break down waste.

Front

Cytoskeleton

Back

A network of protein filaments that maintain cell shape and aid in movement.

Front

Cell Membrane

Back

A phospholipid bilayer that regulates what enters and exits the cell.

Front

Golgi Body

Back

An organelle that modifies, sorts, and packages proteins and lipids.

Front

Vesicle

Back

A small membrane-bound sac that transports and stores substances within a cell.

Front

Mitochondria

Back

The site of cellular respiration, producing energy (ATP) through cellular respiration.
