REMEMBER… Cells without a nucleus or organelles are called: ________________ Cells with a nucleus and organelles are called: _________________ PROKARYOTES EUKARYOTES Bacterial Cell

Copyright Pearson Prentice Hall Nuclear envelope Ribosome (free) Ribosome (attached) Mitochondrion Golgi apparatus Vacuole Nucleolus Nucleus Smooth endoplasmic reticulum Rough endoplasmic reticulum Cell wall Cell membrane Chloroplast Plant Cell

CYTOPLASM Image from: Organelles suspended in gel-like goo… empty space within the cell

NUCLEUS The control center of the cell Largest organelle in animal cells Contains genetic material DNA DNA Nucleolus Nuclear envelope Nuclear pores

Copyright Pearson Prentice Hall The nucleolus is where the assembly of ribosomes begins. Nucleolus NUCLEOLUS

CYTOSKELETON Helps the cell maintain shape Microtubules & Microfilaments Image from: 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:

Copyright Pearson Prentice Hall Ribosomes Endoplasmic Reticulum Two types Rough ER Has ribosomes protein making Smooth ER No ribosomes attached Makes lipids

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:

LYSOSOMES Digest food, unwanted molecules, old organelles, cells, bacteria, etc. Like trash men: they take out the garbage! Also known as suicide sacs

Plant cells: large Animal cells: small Storage space Vacuole VACUOLES

Chloroplast In plant cells Use energy from the sun to make food CHLOROPLAST

DIFFERENCES IN ANIMAL CELLS, PLANT CELLS, AND BACTERIA ANIMAL CELLPLANT CELLBACTERIA Eukaryotes Prokaryotes Cell membrane Nuclear membrane NO nuclear membrane NO cell wallCell wall made of CELLULOSE Cell wall made of PEPTIDOGLYCAN Has ribosomes DNA in multiple chromosomes DNA is a single circular ring CYTOSKELETON Small vacuolesReally big vacuoleNO vacuoles Has lysosomes NO lysosomes Has centriolesNO centrioles NO chloroplastsChloroplastsNO chloroplasts SMALLERSMALLSMALLEST
