smooth ER

Back 8

responsible for the transport and storage of materials manufactured by the cell.

Front 9

Rough ER

Back 9

responsible for the transport and storage of materials manufactured by the cell. Has ribosomes all over its surface.

Front 10

Golgi Apparatus

Back 10

produces lysosomes. kills any intruders to the cell.

Front 11

Passive Movement

Back 11

movement of small molecules or ions across the cell which costs no energy(ATP)

Front 12

Active Transport (movement)

Back 12

movement of stuff across the cell membrane- costs the cell energy

Front 13

endocytosis or phagocytosis

Back 13

when a cell engulfs another solid substance, this also costs energy, in the form of ATP.

Front 14

Diffusion

Back 14

random movement of molecules or ions due to kinetic energy. (does not cost the cell any energy)

Front 15

Facilitated Diffusion

Back 15

a process by which substances are transported across cell membranes by means of protein carrier molecules(free)

Front 16

Osmosis

Back 16

THe passive movement of water though a semi-permeable membrane (free)

Front 17

Tonicity

Back 17

how salty/ or the amount of electrolytes or ions

Front 18

mitosis

Back 18

the divison of cells a cell makes an exact duplicate all cells do this except brain and sex cells.

Front 19

meiosis

Back 19

the process of making sex cells. only occurs in ovaries and testes. from 48 > 24 only one of the four sex cells will be fertilized.

Front 20

how are mitosis and meiosis different?

Back 20

meiosis 4 identical sex cells and chromosomes are halved 48 > 24. mitosis produces 2 identical cells.

Front 21

Molecules of life

Back 21

Sugars
Peptides
Lipids

Front 22

Sugar

Back 22

Carbohydrates
-single sugar monosaccharide
-2 sugars disaccharide
-many sugars polysaccharide

Front 23

Peptides

Back 23

Amino Acids- Build Protein.

Front 24

Lipids

Back 24

Fats

Front 25

Why do cells divide?

Back 25

reproduction, repair, tissue growth

Front 26

Sugars play a role in

Back 26

Energy storage
structure
cellular fuel

Front 27

Where in your body would you find epithelial tissue?

Back 27

surfaces, organs, cavities, and tubes.

Front 28

What does epithelial tissue do?

Back 28

protects, covers glands, lines cavities, absorbs nutrients, sensory output, manufactures secretions.

Front 29

Special features of epithelial tissue.

Back 29

covers about 90% of your body provides insulation,

Front 30

Simple

Back 30

one layer thick

Front 31

Stratified

Back 31

stacked for protection

Front 32

cubodial

Back 32

found in ducts associated with hollow tubes. Exocrine glands(salivary, pancreas, sweat)

Front 33

simple columnar

Back 33

one layer tall narrow cells found in the lining of the small intestine

Front 34

pseudostratified columnar

Back 34

found in the respiratory tract appears to be stratified but is really only one layer thick (simple)

Front 35

simple squamous

Back 35

Flat hexagonal shaped cells-one layer
found around areas where diffusion, osmosis, and filtration occur.
Osmosis in capillaries
diffusion in the alveoli
filtration in the kidneys

Front 36

Stratified Squamous

Back 36

designed for protection-very thick
where skin has contact with internal structures.
ex-ear,vaginal,rectum, mucus membranes.

Front 37

transitional

Back 37

only found in ureters, urinary bladder, and urethra.uterus
Very Stretchy-stratified.

Front 38

glandular aka goblet cells

Back 38

make up all glands- endocrine and exocrine.

Front 39

Connective Tissue-Blood

Back 39

Carries nutrients and waste circulates

Front 40

Connective Tissue-Hematopoietic

Back 40

produces blood cells (forms bone marrow)

Front 41

Connective Tissue-Areolar

Back 41

Loose connective tissue/combined with adipose tissue

Front 42

Connective Tissue-Adipose

Back 42

Fat storage of triglycerides(fat and oils)

Front 43

Connective Tissue-Fiberous

Back 43

more numerous thickly packed fibers
dense regular CT, dense irregular CT, and elastic CT

Front 44

Connective Tissue-Cartilage

Back 44

Specialized tissue that is rigid but will flex and is resilient.

Front 45

Connective Tissue-Bone

Back 45

A living tissue capable of remodeling and repairing itself when damaged. storage of mineral and for movement

Front 46

Back 46

Skeletal-attached to bones (voluntary movement)
smooth- located in the walls in hollow organs. (involuntary movement)
