1
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
2
CYTOPLASM Organelles suspended
In gel-like fluid… empty space within the cell Image from:
3
NUCLEUS Control center of the cell (brain of the cell)
Largest organelle in animal cells Contains genetic material DNA DNA Nucleolus
4
Copyright Pearson Prentice Hall
NUCLEOLUS The nucleolus is where the assembly of ribosomes begins Nucleolus Copyright Pearson Prentice Hall
5
MITOCHONDRIA Singular: Mitochonrion Plural: Mitochondria
The “powerhouse” of the cell Converts energy into useful energy for the cell Mitochondria
6
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
7
RIBOSOMES Protein producing factories
Can be attached to Rough ER or free in cytoplasm Image from:
8
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:
9
LYSOSOMES Digest food, unwanted molecules, old organelles, cells, bacteria, etc. Like trash men:They take out the garbage Also known as suicide sacs
10
VACUOLES Storage for water, food, wastes
Plant cells: typically 1 large Animal cells: many small Vacuole
11
CHLOROPLAST In plant cells only
Use energy from the sun to make food (glucose) Chloroplast
12
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
