A&p Cell Structure Ch3

Front 1

DNA

Back 1

Deoxyribonucleic acid, genetic material found in the nucleus

Front 2

Nuclear Membrane or Envelope

Back 2

double membrane surrounding the nucleus,covered with pores (fluid between membranes)

Front 3

Nuclear Pores

Back 3

penetrate through the fused portion of nuclear membrane selectively permeable but passage freer d/t large pores

Front 4

Nucleoplasm

Back 4

jelly like substance in which other nuclear elements are suspended

Front 5

Nucleoli

Back 5

(little nuclei)round bodies where ribosomes are assembled,

Front 6

Chromatin/Chromosomes

Back 6

Cromatin bumpy threads in nucleus that form the chromosomes during dividing

Front 7

Plasma Membrane

Back 7

transparent membrane that contain the cells content

Front 8

Phospholipids

Back 8

the basic fabric of the plasma membrane lollipop shaped,head hydrophilic,tail hydrophobic

Front 9

Microvilli

Back 9

tiny fingerlike projections that increase cell surface area for absorption

Front 10

Cytoplasm

Back 10

the cellular material outside the nucleus and inside the plasma membrane

Front 11

Organalles

Back 11

(little organs)the metabolic machinary of the cell

Front 12

Mitachondria

Back 12

sausage shaped organalle, contains enzymes that break down food to form energy (ATP)

Front 13

Ribosomes

Back 13

tiny, dark bodies made of protiens acual site of protien synthesis

Front 14

Rough endoplasmic reticulum
or Rough ER

Back 14

Studded with ribosomes protiens are formed into 3 dimentional shapes & sent to other parts of cell in vesicles

Front 15

Smooth endoplasmic reticulum or Smooth ER

Back 15

fonctions in lipid metabolism,abundant in liver cell and body cells that produce hormones

Front 16

Gogli Apparatus

Back 16

Traffic director for cellular protiens sent to plasma membrane in vesicle, attach to plasma membrane and ejected to the out side of cell

Front 17

Lysomes

Back 17

Membanous sacs containing digestive enzymes that digest worn out or non usable cell structures

Front 18

Paroxisomes/paroxide bodies

Back 18

membranous sacs containing oxidase enzymes that use molecular O2 to detoxify harmful or poisonous substances

Front 19

Cytoskeleton

Back 19

elaborate network of protien structures in the cytoplasm that form the "bones&muscles" of the cell

Front 20

Centrioles

Back 20

durring cell division direct the formation of the miotic spindles

Front 21

Flagella

Back 21

the only example of a flagellated cell in the human body is male sperm refering to the tail

Front 22

Cilia

Back 22

whisperlike cellular extentions that move substances along the cell surface
