part of cells and their functions

Cytoplasm

Jelly-like fluid where chemical reactions occur.

Cell membrane

Controls what enters and leaves the cell.

Nucleus

Contains DNA and controls cell activities.

Mitochondria

Produces energy for the cell.

Ribosomes

Make proteins.

Endoplasmic reticulum (ER)

Helps make and transport proteins and lipids.

Golgi apparatus

Packages and ships proteins.

Vacuole

Stores water, nutrients, and waste (larger in plants).

Cell wall

Provides support and protection.

Chloroplasts

Carry out photosynthesis to make food.

Large central vacuole

Maintains cell shape and stores water.

Lysosomes

Break down waste and old cell parts.

Centrioles

Help organize cell division.

Nucleolus

Makes ribosomes inside the nucleus.

Cytoskeleton

Gives the cell shape and helps with movement inside the cell.

Rough endoplasmic reticulum

Has ribosomes and helps make proteins.

Smooth endoplasmic reticulum

Makes lipids and helps detoxify substances.

Vesicles

Transport materials within the cell.

Peroxisomes

Break down fatty acids and harmful chemicals.

Plasmodesmata

Channels that allow substances to move between plant cells.

Cilia / Flagella

Help the cell move or move substances past the cell.
