Flashcards in Chapter 4- Review For Test Deck (56):
1

Why r cells small??

If a cells grows beyond a certain limit it'll pop and/or won't be able to provide for itself

2

NOW CELL THEORYS

LOOK AT OTHER PACK OF CARDS ❤️❤️❤️

3

Know scientists

Look at other set of cards ❤️

4

What increase faster... Surface area vs volume??

Volume

5

What has type of cell has the most organelles??

Eukaryotes

6

Cell theories

- Come from other cells
- made of cells
- smallest living unit

7

The arm and base r used to:

Hold together and allow easier movement of the microscope

8

Revolving nose piece

Ablility to switch between objectives

9

Lamp

Easier to see objective slide

10

Stage

Support slide

11

Body

Connects eyepiece to microscope

12

Eyepiece

-10x magnification
-allows u to see slide

13

Diaphragm

Adjusts light

14

Coarse adjustment

- roughly focused object

15

Fine adjustment

-fine focus

16

Stage clips

Keeps slide in place

17

Low power

X4 magnification

18

High power

10x magnification

19

Cells plasma membrane

Allows objects to leave and enter cell

20

Phospholipid bilayer

Semi-permeable

21

Transport proteins______

Sometimes act as a door into the cell

22

4 levels of organization

Cells-> tissue-> organ -> organ system

23

Cytoplasm

-keeps cells in place
- jelly like
- animal and plant

24

Nucleus

Central center
-animal and plant

25

Nucleolus

-contains DNA in the cell
- plant and animal

26

Centrioles

-make fibers
- help with cell division
-animal cell

27

Mitochondria

-make ATP
-plant and animal

28

Ribosomes

-make proteins
-plant and animal

29

Rough Endoplasmic Reticulum

Synthesisis
-steroids
- phospholipids
- proteins
-animals and plant

30

Smooth ER

- synthesis Steroids and proteins
- animal and plant

31

Golgi Body

- "shipping and receiving" center
-animals

32

Vacuoles

Storage for cell
-animal and plant

33

Lysosomes

-'garbage"
-break down things
- animal and plant

34

Cilia

-used for movement
- animal

35

Flagella

-used for movement
- animal

36

Cell wall

-cells shape
-plant

37

Chloroplast

-makes energy through ATP for the cell
-plant

38

Diffusion

When somethings Completly and evenly spreads out

39

Osmosis

When water diffuses

40

Active transport

Movement of cells through the membrane with energy

41

Passive transport

Movement of cells through the membrane without energy

42

Concentration gradient

Process of when particles move from one area to another

43

Turgor pressure

Pushes the cell membrane against the cell wall
(Keeps it from collapsing in)

44

A substance that can pass through the cell membrane (easily)

Oxygen

45

Hypotonic

Too much

46

Hypertonic

Shriveled/not enough

47

Isotonic

Equal

48

Simple diffusion

-passive transport
•no energy used
•high to low

49

Facilitated transport

-passive transport
-high to low
-protein needed to cross membrane

50

Active transport

-uses a form of ATP fro energy
-low to high
-requires a protein or pumps to cross the membrane

51

Active transport

Movement across the cell membrane

52

Vesicle

Organelle in cells membrane bound sac

53

Phagocytosis

Brings things in through endocytosis

54

Sodium is pumped _____ and potassium is pumped _______

NA + ie released _____ of the cell

Out

56

K+ ion released ____ the cell

In
