The Cell Theory All living things have cells Cells are the basic unit of life. Cells arise (come) from other cells!

Prokaryotes vs Eukaryote Simpler Smaller More complex No nucleus more specialized organelles a nucleus Ex. Bacteria Ex. Animals, plants mushroom protist

Protist, a single celled organism. One cell big!!!

Cell Comparison Prokaryote vs Eukaryote

A. Nucleus Controls cell activities, stores genetic information. Surrounded by nuclear membrane DNA is here!! Nucleolus is a small dense area where ribosome assembly begin.

B. Ribosome's Small particles of RNA and protein that assemble proteins. “makes proteins”

Endoplasmic Reticulum Rough ER: synthesis (making) of proteins. It’s called rough because the ribosome's on it look like bumps. Smooth ER: contain specialized enzymes,like those that detoxify (liver) and make lipids for cell membrane.

D. Golgi Apparatus Modify (changes), sorts, and packages proteins from ER. organizes and delivers! “pancake stack”

E. Lysosomes Uses enzymes to break down molecules and dead bacteria…cleans up!

F. Vacuoles Stores materials such as water, salts, proteins, and carbs. Create pressure to maintain shape, like leaves.

G. Mitochondria and Chloroplast 1. Mitochondria convert food to ATP ENERGY that can be used by the cell. – Found in plants and animals 2. Chloroplast capture energy from the sun and convert into chemical ENERGY in the process of photosynthesis. – Found mostly in plants and some photosynthetic bacteria.

H. Cytoskeleton Cell wall in plants: made of cellulose Microtubules and centrioles, give shape and structure
