16
Q

Interphase

A

Mitosis Stage 1

- Resting phase.

17
Q

Prophase

A

Mitosis Stage 2
- centrioles start to separate, microtubules form between them. Nuclear membrane begins to dissolve. Nucleolus disappears. DNA in chromosomes coils tighter

18
Q

Metaphase

A

Mitosis Stage 3

- nuclear membrane completely dissolved. Chromatid pairs line up single file in the equatorial plate

19
Q

Anaphase

A

Mitosis Stage 4

- chromatid pairs separate and are pulled towards their centrioles

20
Q

Telophase

A

Mitosis Stage 5

- chromosomes start to uncoil. Nucleolus and nuclear membrane reform

21
Q

Diffusion

A

Passive transport type.

Molecules move from an area where they are greatly concentrated into an area where they are less concentrated

Even distribution means it’s reached an equilibrium

22
Q

Osmosis

A

Passive transport type

Diffusion if water molecule through a selective permeable membrane.

23
Q

Filtration

A

Passive transport type

Molecules through a semipermeable membrane via some mechanical force such as blood pressure or gravity

24
Q

Phagocytosis

A

Active transport type

Cell eating. Substance engulfed are within particles

25
Q

Pinocytosis

A

Active transport type

Cell drinking. Substance engulfed is within a solution
