Front 3

Chromosones

Back 3

Carry genes in the form of DNA (within the nucleus)

Front 4

Ribosomes

Back 4

Tiny complexes made of rRNA and protiens that make protiens according to instruction froms the gene

Front 5

Eukaryotic Cell

Back 5

DNA is enclosed within a nucleus

Front 6

Prokaryotic Cell

Back 6

DNA is concentrated in the Nucleoid

Front 7

Cytoplasm

Back 7

The interior of the cell (In eukaryotes, area between plasma membrane and nucleus)

Front 8

Nucleus

Back 8

contains most of genetic info in eukaryotes

Front 9

Nuclear envelope

Back 9

encloses the nucleus

Front 10

Nuclear lamina

Back 10

protiens filaments that maintain nucleus shape

Front 11

Nucleolus

Back 11

location of of rRNA synthesis

Front 12

rRNA

Back 12

ribsomal RNA

Front 13

mRNA

Back 13

messenger RNA

Front 14

DNA

Back 14

Genetic sequence of life

Front 15

Free ribosomes

Back 15

ribosomes suspended in cytosol

Front 16

Suspended ribosomes

Back 16

attached outside the ER or nuclear envelope

Front 17

Endomembrane system

Back 17

includes nuclear envelope, ER, golgi apparatus, lysosomes, vesicles, caluoles, and the plasma memberane.

Front 18

Vesicles

Back 18

sacs made of membrane

Front 19

Endoplasmic Reticulum (ER)

Back 19

A network of tubules and sacs called cisternae. Very big.

Front 20

Smooth ER

Back 20

lacks ribosomes on it's surface. Synthesizes lipids, metabolizes carbs, Ca2+ storage, detoxes drugs and poisons.

Front 21

Rough ER

Back 21

Aids in synthesis of protiens and glycoprotiens, adds carbs to protiens, produces new membrane.

Front 22

Glycoprotiens

Back 22

Protiens that have carbs covalently bonded to them

Front 23

Transport vesicles

Back 23

vesicles carrying protiens from one part of the cells to another

Front 24

Golgi Apparatus

Back 24

Stores, modifies, and sends ER products such as protiens

Front 25

Lysosome

Back 25

membranous sac of hydrolytic enzymes that animal cells use to digest macromolecules

Front 26

Phagocytosis

Back 26

Protist technique of engulfing smaller organisms and food

Front 27

Contractile vacuoles

Back 27

Vacoules used by freshwater protists pump excess water out of the cell

Front 28

Central vacoule

Back 28

Vacuoles used by plant cells which holds plants main repository of inroganic ions

Front 29

Mitochondria

Back 29

sites of cellular respiration

Front 30

Chloroplasts

Back 30

sites of photosysnthesis

Front 31

Cristae

Back 31

Infoldings in in the mitochondria's membrane

Front 32

Mitochondrial matrix

Back 32

area within mitochondria's inner membrane that contains mitiochondrial DNA, ribosomes, and enzymes for respiration.

Back 33

interconnected sacs within chloroplasts

Front 34

Stroma

Back 34

fluid outside thylakoids

Front 35

Peroxisome

Back 35

specialized metabolic compartments bounded by single membrane

Front 36

Cytoskeleton

Back 36

series of microtubules, microfilaments, and intermediate fillaments that cupport cell shape.

Front 37

Micortubules

Back 37

shape the cell, guide organelle movement and separate chromosomes

Front 38

Microfilaments

Back 38

thin rods that function in muscle contraction, amoeboid movement, cytoplasmic straming, and microvillus support

Front 39

Intermediate filaments

Back 39

support cell shape and fix organelles into place

Front 40

Cell wall

Back 40

extracellular structure of plants that protects the cell, maintains its shape and prevents excessive uptake of water.
