Cell Structures: Be able to identify the cell structures of the animal and plant cell! Know the function of each cell structure!

Nucleus: Controls all of the cell’s activities; made up of chromosomes, the nucleolus, the nuclear envelope and nuclear pores.

Nucleolus: Dark, dense, area of fibers and granules in the cell's nucleus; are made of ribosomal proteins and ribonucleic acid.

Chromosomes: DNA; contains genetic material

Nuclear Envelope: A membrane that covers the nucleus and controls what enters and leaves the nucleus.

Nuclear Pore: Openings that allow the transport of water-soluble molecules across the nuclear envelope.

Endoplasmic Reticulum rough ER-transports substances throughout the cell. smooth ER – makes lipids & breaks down toxic substances

Golgi Apparatus: Packages and ships out substances.

Mitochondria: Makes energy (ATP) for the cell.

Lysosome: Contains digestive enzymes that helps break down substances for the cell.

Vacuole: Stores water, food, ions, and waste for the cell.

Ribosomes: Makes proteins.

Cytoskeleton: A network of protein fibers that gives the cell shape and support; is also involved in cell movement.

Cytoplasm: Jelly-like liquid substance that contains or holds the cell’s organelles.

Centrioles: Cylindrical structures made up of microtubules; they help divide the DNA during cell division.

Cell Membrane: A membrane that covers the cell; it controls what enters and leaves the cell.

The Animal Cell:

Chloroplast: Contains chlorophyll and makes food for the plant cell through photosynthesis.

Cell Wall: Supports and protects the plant cell.

The Plant Cell:
