A

Solution is below strength in solute

25
Q

Function of the contractile vacuole

A

Comes access water out of the cell

26
Q

Facilitated diffusion

A

Glucose that can’t pass the lipid bilayer moves across the protein channel

27
Q

Endocytosis

A

Large amounts of material are transported through movement of the cell membrane

28
Q

Phagocytosis

A

Large particles are taken in the cell by endocytosis

29
Q

Exocytosis

A

Removal of large amounts of material

30
Q

Levels of organization

A

Cells, tissues, organs, organ system

31
Q

Why do the cells divide

A

The more it grows the more demands are placed on DNA and material has a hard time moving across the membrane

32
Q

Cell division

A

The process of a cell divides into two new daughter cells, complete genetic information

33
Q

When chromosomes become visible at the beginning of cell division what does each chromosome consists of

A

Centromere and sister chromatids

34
Q

Centromere

A

Where the chromatids are attached the center of the chromatids

35
Q

Interphase

A

In between period of growth

36
Q

Cell cycle

A

The series of events the sale goes through to divide, mitosis and interphase

37
Q

Interface is divided into what three phases

A

G1 s G2

38
Q

What happens during the G1 phase

A

The. Were cells do most of their growing

39
Q

What happened during the S-phase

A

Chromosomes replicate and synthesis takes place

40
Q

What happens during the G2 phase

A

Organelles and molecules needed it for the division are produced

41
Q

What are the four phases of mitosis

A

Prophase, metaphase, anaphase, telophase

42
Q

Centrioles

A

The tiny structures located in the cytoplasm near the nuclear envelope

43
Q

Spindle

A

Fanlike microtubule that helped to separate the structure

44
Q

Cytokinesis

A

The division of the cytoplasm

45
Q

Cyclins

A

They regulate the timing of the cell cycle in eukaryote cells

46
Q

Internal regulators

A

Proteins that respond to events inside the cell

47
Q

Cancer

A

Uncontrolled cell growth

48
Q

When are chromosomes visible

A

Cell division

49
Q

Prophase

A

The chromosomes become visible, the centrioles take a position on opposite sides of the nuclear us

50
Q

Metaphase

A

The chromosomes line up across the center of the cell

51
Q

Anaphase

A

The chromosomes move until they form two groups near the poles of the spindle

52
Q

Telophase

A

The nuclear envelope reforms around each cluster of chromosomes, the new keyless becomes visible in each daughter nuclear us

53
Q

Happens to the south the edge of an injury

A

The cell begins to divide fast to fill the space

54
Q

What is the function of the nuclear us

A

Charles most cell processes contains hereditary information in DNA

55
Q

What is found in the nuclear us

A

Nucleosis chromatin and DNA

56
Q

Ribosome

A

And internal membrane system in which components of the cell membrane and some proteins are constructed also acts as a transport system

57
Q

Lysosome

A

Filled with enzymes used to break down food and organelles that have outlived their usefulness

58
Q

Vacuole

A

Saclike structure that stores materials

59
Q

Chloroplast

A

Uses energy from the sunlight to make energy rich foods, only implants

60
Q

Mitochondrial on

A

Use energy from food to make high-energy compounds, inner and outer membrane

61
Q

When will the water stop moving across a membrane

A

Never, it gets close when it reaches the equilibrium
