Cell Organelles (fill in the blanks as you view the power point) Cells without a nucleus or organelles are called: _PROKARYOTES_ Cells with a nucleus and organelles are called: _EUKARYOTES_ 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 fluid… empty space within the cell Image from: http://faculty.stcc.cc.tn.us/jiwilliams/labprojectsmenu.htm

NUCLEUS Control center of the cell (brain of the cell) Largest organelle in animal cells Contains genetic material DNA DNA Nucleolus

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

MITOCHONDRIA Singular: Mitochonrion Plural: Mitochondria The “powerhouse” of the cell Converts energy into useful energy for the cell Mitochondria

ENDOPLASMIC RETICULUM Passageways that moves material from one part of the cell to another • Rough ER •Has ribosomes Makes proteins Smooth ER No ribosomes attached Makes lipids Ribosomes Copyright Pearson Prentice Hall

RIBOSOMES Protein producing factories Can be attached to Rough ER or free in cytoplasm Image from: http://www.biologyclass.net/endoplasmic.jpe

GOLGI APPARATUS (or GOLGI BODY) Modify, sort, & package molecules from ER for 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 Storage for water, food, wastes Plant cells: typically 1 large Animal cells: many small Vacuole

CHLOROPLAST In plant cells only Use energy from the sun to make food (glucose) Chloroplast

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 Small vacuoles Really big vacuole NO vacuoles Has lysosomes NO lysosomes Has centrioles NO centrioles NO chloroplasts Chloroplasts SMALLER SMALL SMALLEST
