Animal Cell Structure and Function

Cell Membrane Made up of Lipids, Protein and Carbohydrates Forms a lipid bi-layer

Inside Protein Outside Antennae (Carbohydrates) Tail Head

Functions of Cell Membrane Controls what molecules enter and exit the cell Protects and Supports the cell Helps cell communicate with other cells

Cytoplasm Structural Features  Jelly like material made of water, salt and organic compounds Function  Contains organelles

Endoplasmic Reticulum (ER) System of membranous tubules and sacs Can be rough: with ribosomes attached Can be smooth: no ribosomes

Functions of the ER Rough ER  Site of new protein production Smooth ER  “Highways” that proteins move through and storage site for proteins

Mitochondrion Structural Features  Bean Shape  Surrounded by 2 membranes Functions  Energy center or “Powerhouse” of the cell  Turns food into useable energy (ATP)

Nucleus Structural Features  Surrounded by a double membrane called the Nuclear Membrane or Envelope  Has pores  Contains Chromatin: DNA & Protein  Contains the Nucleolus which makes ribosomes  Contains Nucleoplasm which is cytoplasm of the nucleus

Functions of the Nucleus Directs all cell activities; reproduction and protein production “Brains” of the cell

Ribosomes Structural Features  Small, globular (round) organelles Function  Site of protein synthesis (production)

Lysosome Structural Features  Tiny, round organelle  Single Membrane  Contains many enzymes Function  Digests food particles, bacteria and broken cell parts

Golgi Apparatus Structural Features  Flattened stacks of membranes (Pancakes) Function  Processes, modifies and packages proteins

Microtubules Structural Features  Long, slender protein tubes Function  Supports cell

Flagella Structural Features (2 Types)  Many small hair like projections  One large tail Function  Gives cell the ability to move

Flagella Cell Membrane Smooth ER Lysosome Microtubules Golgi Apparatus Ribosomes Mitochondrion Rough ER Ribosomes Nucleolus Nuceloplasm Nuclear Membrane
