Cell Biology Flashcards

Front

Nucleus

Back

The control center of the cell that contains DNA and regulates gene expression.

Front

Mitochondria

Back

The powerhouse of the cell; generates ATP through cellular respiration.

Front

Ribosomes

Back

Organelles that synthesize proteins; can be free-floating or attached to the rough ER.

Front

Endoplasmic Reticulum (Rough)

Back

A network of membranes with ribosomes that assists in protein synthesis and folding.

Front

Endoplasmic Reticulum (Smooth)

Back

Involved in lipid synthesis, detoxification, and calcium ion storage.

Front

Golgi Apparatus

Back

Modifies, sorts, and packages proteins and lipids for transport.

Front

Lysosomes

Back

Contain digestive enzymes to break down waste and cellular debris.

Front

Chloroplasts

Back

Found in plant cells; carry out photosynthesis to produce glucose and oxygen.

Front

Vacuoles

Back

Storage sacs for water, nutrients, and waste; large central vacuole in plant cells.

Front

Plasma Membrane

Back

A selectively permeable lipid bilayer that regulates what enters and exits the cell.
