Ap Bio- The Cell

Front 1

What is the difference between prokaryotic cells and eukaryotic cells?

Back 1

PROKARYOTES:
-no nucleus (nucleoid region)
-no membrane bound organelles
-circular DNA (plasmid)
-smaller ribosomes
-no mitosis to reproduce

Front 2

plasma membrane (2)

Back 2

-selectively permeable
-made of phospholipids, proteins, and carbohydrates.

Front 3

nucleus (3)

Back 3

-contains DNA
-transcribes mRNA
-enveloped in nuclear envelope

Front 4

chromatin (2)

Back 4

-DNA and proteins
-condense into chromosomes in Mitosis

Front 5

nucleolus (3)

Back 5

-exists in a NONDIVIDING NUCLEUS
-produces rRNA
-not enclosed by a membrane

Front 6

ribosomes (3)

Back 6

-protein synthesis
-consist of rRNA and protein
- found floating in cytoplasm or on rough ER

Front 7

smooth ER (2)

Back 7

- function is synthesis of membranes and lipids and metabolism of carbohydrates
- made up of membranes and sacs called cisternae

Front 8

rough ER (2)

Back 8

-function is protein synthesis
-proteins excreted from rough ER in transport vesicles

Front 9

golgi apparatus (3)

Back 9

-receive proteins from rough ER and modifies protein
-composed of flattened sacs of membrane called cisternae
-these sacs have different polarities:
cis receives vesicles, trans ships vesicles out

Front 10

mitochondria (2)

Back 10

-place of cell resipiration
- creates ATP

Front 11

peroxisomes (1)

Back 11

-create and destroy own hydrogen peroxide

Front 12

cytoskeleton

Back 12

-organizes cell structures
