Flashcards in Cell Parts Actual Test Deck (48):
1

Describe the characteristic pf mitochondria that makes them well suited for their role

They have double membrane that helps them build up different concentration gradients

2

Cells of the stomach lining have large numbers of ribosomes and Golgi explain

They need many enzymes to they to manufacture and distribute them

3

How does a cell membrane differ from a cell wall

Cell membrane is made of phospholipids and cell wall is made of cellulose, rigid and only in plants

4

What does the rough Er have attached to it

Ribosomes

5

What organelles are only found in plants and what are only found in animals

Chloroplast and cell Walls
Centrioles

6

Water moves into a cell in a --- solution

Hypotonic

7

Water moves out of a cell if the cell is placed in a --- solution

Hypertonic

8

If cells are placed in a strong sugar solution water will

Move out of the cell

9

A cell moves particles from a region of lesser concentration to greater concentration by

Active transport

10

If a tulip is not watered or wilts because

The vacuole loses water

11

If a cell is placed in salt water, water leaves the cell by

Osmosis

12

Facilitated diffusion

Diffusion through a channel protein

13

Endocytosis

Active transport bringing substances into the cell

14

Exocytosis

Getting things out of cell using energy

15

Phagocytosis

Moving food into your cell using energy

16

Pinocytosis

Moving liquid into your cell using energy

17

Lysis

When cell explodes because water moves into cell (towards hypertonic)

18

Plasmolysis

When the cell shrinks due to water moving out of the cell

19

Hypertonic

More solute than solvent

20

Isotonic

Both sides equal

21

Hypotonic

Less solute than solvent

22

Diffusion

Passive transport of substances not water, from high to low concentration

23

Osmosis

The diffusion of water

24

Structure responsible for homeostasis

Cell membrane

25

Movement of particles from high concentration to low

Diffusion

26

Cellular eating

Phagocytosis

27

Movement of food particles into the cell using energy

Endocytosis phagocytosis

28

Loss of water from a cell resulting in a drop in turgor pressure

Plasmolysis

29

Diffusion of water molecules through a selectively permeable membrane

Osmosis

30

Release of wastes or cell products from inside to outside of a cell

Exocytosis

31

Active transport differs from passive

Active moves against the gradient ad they require energy to do so

32

Where is all the cellular energy needed for the cell made and how is it stored

Made in the chloroplast and it is stored in glycogen and starch

33

What do carbohydrates break down to

Monosaccharides

34

Lipids break down to

Fatty acids

35

Proteins break down to

Amino acids

36

Nucleic acids break down to

Nucleotides

37

What are two types of membrane proteins and what are their functions

Channel proteins: facilitated diffusion
Transport proteins: active transport or large molecules

38

When a lysosomes collides with a food vacuole what happens

They would digest the food in the vacuole

39

What packages materials for removal from the cell

Golgi body

40

How do materials get passed out of cell

Exocytosis

41

What contains identification markers for other cells

Cell membrane

42

In the final phase of completion, proteins are modified by special enzymes in what organelle

Golgi apparatus

43

What produces ATP

Mitochondria

44

Cell membranes are mostly composed of

Proteins and lipids

45

What structure is the site of protein synthesis

Ribosomes

46

What are found in every living cell

Cell membrane and ribosomes

47

What factors increase the Rate of diffusion

Distance, concentration of substance, and weight of molecules

48

Why is surface area to volume ratio important for cells

The ratio must remain small for the transport of molecules
