EUKARYOTES PROKARYOTES REMEMBER… Cells with a nucleus and organelles are called: _________________ Cells without a nucleus or organelles are called: ________________ EUKARYOTES PROKARYOTES Bacterial Cell http://www.earthlife.net/prokaryotes/welcome.html http://summit.k12.co.us/schools/shs/computer/tkelley/types.html
CYTOPLASM Organelles suspended in gel-like goo… empty space within the cell Image from: http://faculty.stcc.cc.tn.us/jiwilliams/labprojectsmenu.htm
NUCLEUS The control center of the cell Largest organelle in animal cells Contains genetic material DNA DNA Nuclear envelope Nucleolus Nuclear pores
Copyright Pearson Prentice Hall NUCLEOLUS The nucleolus is where the assembly of ribosomes begins. Nucleolus Copyright Pearson Prentice Hall
CYTOSKELETON Helps the cell maintain shape Image from: http://anthro.palomar.edu/animal/default.htm CYTOSKELETON Helps the cell maintain shape Microtubules & Microfilaments Image from: © Pearson Education Inc, Publishing as Pearson Prentice Hall; All rights reserved
MITOCHONDRIA Singular: Mitochonrion Plural: Mitochondria The “Powerplant” of the cell Stores energy in the form of ATP Mitochondria
RIBOSOMES Can be attached to Rough ER OR free in cytoplasm. This is where proteins are made! Image from: http://www.biologyclass.net/endoplasmic.jpe
Endoplasmic Reticulum Two types Rough ER Has ribosomes protein making Smooth ER No ribosomes attached Makes lipids Ribosomes Copyright Pearson Prentice Hall
GOLGI APPARATUS Modify, sort, & package molecules from ER for storage or transport out of cell- like the post office Ships proteins to their final destination. Image from: http://vilenski.org/science/safari/cellstructure/golgi.h
LYSOSOMES Digest food, unwanted molecules, old organelles, cells, bacteria, etc. Like trash men: they take out the garbage! Also known as suicide sacs
VACUOLES Plant cells: large Animal cells: small Storage space Vacuole
CHLOROPLAST In plant cells Use energy from the sun to make food
DIFFERENCES IN ANIMAL CELLS, PLANT CELLS, AND BACTERIA ANIMAL CELL Eukaryotes Prokaryotes Cell membrane Nuclear membrane NO nuclear membrane NO cell wall Cell wall made of CELLULOSE Cell wall made of PEPTIDOGLYCAN Has ribosomes DNA in multiple chromosomes DNA in multiple chromosomes DNA is a single circular ring CYTOSKELETON Small vacuoles Really big vacuole NO vacuoles Has lysosomes NO lysosomes Has centrioles NO centrioles NO chloroplasts Chloroplasts SMALLER SMALL SMALLEST
