Objective: What are the structures and functions of cell organelles? Do Now: What are 3 things that a plant cell has that an animal cell does not have?

Cell Membrane - A barrier that regulates what enters and leaves the cell

Cytoplasm - Jelly-like substance made of cellulose which contains all of the organelles

Nucleus/Nuclear Envelope - Nucleus: controls cell activities (contains DNA) - Nuclear Envelope: separates contents of nucleus from rest of the cell

Ribosomes Where proteins are assembled

Endoplasmic Reticulum (ER) Rough ER (highway) : -(rough b/c of ribosomes on surface) -Proteins are made then transported to Golgi Smooth ER: produces lipids, detoxifies posion

Mitochondria Produces Energy (powerhouse of the cell)

Golgi Body Like a post office Modifies and routes proteins outside of cell via transport vesicles

Cytoskeleton Made up proteins Supports cell

Lysosomes Membrane-bound sacs that contain enzymes Digest food, destroy foreign invaders

Centrioles (animal cells) Important in cell division

Vacuoles Large, membrane-bound sacs Stores nutrients, pigments, salts, etc Contractile vacuoles pump out excess water
