Cell Membrane
Location: in all cells (surrounds inside)
Function: support/protection of cells, chooses what enters/exits the cell, maintains homeostasis
Structure: double layered phospholipids with proteins

Structure: double layered phospholipids with proteins
- in a Plant - inside cell wall
- in an Animal - outer layer; cholesterol
Cell Wall
Location: Plant, Fungi and Bacteria (surrounds)
Function: Supports/protects the cell, keeps the cell its shape, allows plants to grow great high
Structure: rigid, strong, outermost layer

Structure: rigid, strong, outermost layer
Centrioles
Location: Animal cells (near nucleus)
Function: separates chromosome pairs during mitosis and meiosis,
Structure: found in pairs which move towards the poles (opposite ends) of the nucleus when it is time for cell division.

Chloroplasts
Location: Plants and Algae
Function: converts light energy of the Sun into sugars that can be used by cells (photosynthesis)
Structure: membrane envelope, thylakoid membrane, grana, stroma, and chlorophyll.

Chromosomes and chromatin
Location: inside the nucleus, all cells
Function: Holds DNA for cell division
Structure of Chromosomes: DNA packed inside
Structure of Chromatin: DNA and RNA
Function: Holds DNA for cell division
Structure of Chromosomes: DNA packed inside
Structure of Chromatin: DNA and RNA
Cilia/Flagella
Location: Animal, Bacterial cells & Protozoans
Function: move liquid past the cell
Sturcture: have a 9-2 microtubules, cillilas are short but has lots of them. Flagella is long and has very few.

Cytoplasm
Location: all cells (in cell membrane)
Function: holds all of the organelles in place
Sturcture: clear, thick, jellylike material
Function: holds all of the organelles in place
Sturcture: clear, thick, jellylike material
Cytoskeleton
Location: all cells (inside cytoplasm)
Function: if no cell wall then determinds the shape, moves organelles thoughout the cell,
Sturcture: thick, look like tubes
