Cells and Organelles

Cell (plasma) membrane

Structure: Semi-permeable membrane surrounding cell

Function: “traffic cop” it selects what enters the cell

Nucleus

Structure: Spherical, often in center of cell, bounded by membrane

Function: cell brain or computer of the cell, contains genetic information

Cytoplasm

Structure: Semi-fluid between the cell membrane and the nucleus

Function: Jelly-like substance within cell that holds up other parts in cell

Vacuole

Structure: Membrane bound sack in plant cell

Function: warehouse in cell that stores food and waste products

Cell wall

Structure: Surrounds a plant cell

Function: supports and provides rigidity for cells

Mitochondria

Structure: Shaped like jelly bean or peanut

Function: powerhouse of the cell, creates energy for cell

Chloroplasts

Structure: Green, similar shape to mitochondria

Function: spot of photosynthesis where food is made for plant cells

Endoplasmic Reticulum

Structure: white, maze-like cell part surrounding nucleus

Function: used to transport food or other materials from one part of cell to another

Ribosomes

Structure: Tiny, round, floats around cytoplasm or attaches to ER

Function: creates protein

Golgi Apparatus (body)

Structure: Stacks of saucer-like membranes

Function: transports materials out of the cell in vesicles
