golgi body function...

Back 14

materials transforms into forms cells can use

Front 15

lysosomes function...

Back 15

digests wastes

Front 16

state the three parts of the cell theory

Back 16

1) all living things are made of cells

2) cells are the basic units of structures and functions in living things

3) living cells come only from other living cells

Front 17

what three structures do only plant cells have?

Back 17

1) cell wall

2) chloroplasts
3) large vacuole

Front 18

what three structures do only animal cells have?

Back 18

1) Centriole

2) Cilia

3) flagella

Front 19

function of the cilia and flagella?

Back 19

move liquid past the surface of the cell (Ex. sperm)

Front 20

phase?

Back 20

prophase

Front 21

phase?

Back 21

metaphase

Front 22

phase?

Back 22

anaphase

Front 23

phase?

Back 23

telophase

Front 24

phase?

Back 24

interphase

Front 25

two reasons why cells divide...

Back 25

1) cell growth

2) cell repair

Front 26

how is cytokinesis in animal cells different from cytokinesis in platn cells?

Back 26

in plant cells, a cell plate forms towards the end of telophase & cytokinesis sees the cell wall growing on the plate

Front 27

how do DNA ,chromosomes , genes and protein relate to each other?

Back 27

-genes are like the blueprint for proteins

-genes code for a single trait

- proteins are like "robots" which catalyze reactions in the cell

DNA-->(winds up)-->chromosome-->gene

Front 28

what causes a mutation in dna? (list 3)

Back 28

-natural causes

-artificial causes

-chemicals

Front 29

what is a tumor?

Back 29

swelling of a part of the body caused by abnormal growth of tissue

Front 30

what is cancer

Back 30

uncontrollable growth of cells, cells may grow at a faster rate and no ability to sense surrounding cells

Front 31

what are the four main organs of a plant

Back 31

1) leaves

2) stem

3)roots

4) flower

Front 32

what is photosynthesis ?

Back 32

process in plants converting CO2 and water into glucose and oxygen using the sun's energy

Front 33

are cells more or less complex than tissue?

Back 33

less complex

Front 34

four major types of animal tissues

Back 34

1) epithelial (skin)

2) nervous (communicates between brain and spinal cord)

3)connective tissue (bones ,fat, blood)

4) muscle ( skeletal, cardiac [only in the heart] )

Front 35

what is a stem cell?

Back 35

unspecialized cells that can produce various specialized cells

Front 36

3 factors that influence cell specialization in animals

Back 36

1) contents of cell cytoplasm

2) environmental conditions

3) influence of nearby cells

Front 37

list in order the sections in which blood pumps through the heart (10 parts)

Back 37

1) right atrium

2) right ventricle

3) pulmonary artery

4) lungs

5) pulmonary veins

6) left atrium

7) left ventricle

8)vena cava

9) aorta

10) body cells

Front 38

vessels carrying blood away from heart...

Back 38

arteries

Front 39

vessels carrying blood TOWARDS heart...

Back 39

Front 41

upper chambers of the heart that recieve blood..

Back 41

Front 42

lower chambers that pump blood out of heart...

Back 42

ventricles

Front 43

only artery in the body rich in carbon dioxide...

Back 43

pulmonary artery

Front 44

the only vein in the body rich in oxygen...

Back 44

pulmonary vein

Front 45

how does the human digestive system cooperate with the circulatory system?

Back 45

blood passes where nutrients are absorbed and carried into the blood stream. circulatory system delivers the nutrients involved in digestion.

Front 46

how does the human respiratory syst. cooperate with the circulatory system?

Back 46

air we breathe goes to lungs where gas exchange occurs. blood vessels surrounds the alveoli. carbon dio. rich blood is carried to lungs where oxygen is exchanged. carbon dio. blown off during exhalation and oxygen goes back to the heart .
