Sci 226 - Cell Organelles and Fuctions

Cell Membrane

gatekeeper to the cell: allows some materials to pass, but not others

Cytoplasm

gel-like fluid that is inside cell

Nucleus

holds the genetic material of the cell (DNA)

Chromosomes

genetic structures that hold the information that the cell needs to make new cells (holds the genes)

Nuclear Membrane

protects and surrounds the nucleus

Nucleolus

inside the nucleus: responsible for making ribosomes

Vacuole

storage center for substances needed by the cell - also stores waste

Mitochondria

POWERHOUSE OF THE CELLS

Ribosomes

produces important proteins and lipids

Endoplasmic Reticulum

Internal delivery system for the cell

Golgi Body

package products from the endoplasmic reticulum and distribute them around / outside of the cell

Cell Wall

PLANT CELL ONLY: provides extra support for the cell and gives it shape: made of cellulose

Chloroplasts

PLANT CELL ONLY: food making structures of plant cells --> contain Chlorophyll

Chlorophyll

PLANT CELL ONLY: captures energy of sun and uses it to drive a chemical reaction to create sugars for the plant
