Cell Wall

plant only, tough, provides support and protection

Plasma Membrane

thin barrier that controls movement of materials in/out of cell, maintains homeostasis (balance)

Cytoplasm

supports organelles, jelly like substance

Nucleus

large, round organelle that controls the cell and holds the DNA

Nucleolus

produces ribosomes

Endoplasmic Reticulum

network of tubes that carries materials through cell. Smooth ER makes lipids (fat). Rough ER makes proteins.

Ribosomes

small, round organelles found on ER or in cytoplasm that produce proteins

Golgi Apparatus

sorts, packages, and sends proteins throughout the cell

Mitochondria

break down glucose (sugar), C6H12O6, molecules to produce energy.

Lysosome

breaks down food molecules and digests old cell parts

Vacuoles

store food, water, waste

Large Central Vacuole

stores water in plant cells. Larger than the Nucleus.

Chloroplasts

use energy from sun to make glucose (sugar) for the plant (photosynthesis)

Cholorphyll

green pigment found in chloroplasts

Cytoskeleton

provides internal structure, located in the cytoplasm

Centrioles

help animal cell division

Organelle

specialized structures that perform specific jobs in the cell

Prokaryote Cell

unicellular cells that do not have a nucleus

Eukaryote Cell

usually multicellular, contain a nucleus and several membrane bound organelles
