Where is the golgi complex located? Near the nucleus.
What is the golgi complex made of? Layered membrane
What are vacuoles? Sacs used for storage, digestion and waste removal
How many vacuoles does a plant cell have? 1 large vacuole
Can animal cells have more than one vacuole? Yes
What is a vesicle? It is a small organelle within a cell.
What does the membrane of a vesicle do? Moves materials within a cell
What is the cytoskeleton made up of? Microtubules that help shape and support the cell.
, What is a microtubule? Part of the cytoskeleton to support the cell.
What are microtubules made up of? Protein
What is cytosol? Material inside of the cell.
What is cytosol made up of? Mostly water, but can have other floating molecules.
What is the cell membrane? Defines the cell by acting as a barrier
What does the cell membrane do? Helps keep the cytoplasm inside and foreign substances outside.
What are the two types of endoplasmic reticulum? Smooth and Rough
What does rough endoplasmic reticulum have? Ribosomes on the outside
What is the endoplasmic reticulum? A tubular network that acts as a transport system.
Fused to the nuclear membrane and extends into cytoplasm.
What does the mitochondria do? Develops ATP, assists cell growth/death
Do mitochondria contain their own DNA? Yes! it is separate from the nucleus.

mitochondria?
What kind of respiration occurs in the mitochondria? Aerobic
What is a centrosome? Involved in mitosis/cell cycle, has a pair of centrioles surrounded by protein
What are centrioles? Cylinder shaped structures near the nucleus used for division.
What does each cylinder centriole have? Nine groups of three microtubules.
What is a lysosome? Structure that digests proteins, lipids, and carbs.
What can the lysosome do? Help transport undigested substances to membrane so it can be removed
