- Diffusion
- Osmosis
- Facilitated diffusion
- Active transport
masalah 3
pilihan
What is the movement of water molecules across a partially permeable membrane called?
- Diffusion
- Active transport
- Osmosis
- Endocytosis
masalah 4
pilihan
Diffusion occurs when molecules move from:
- A low concentration to a high concentration
- A high concentration to a low concentration
- An area of equal concentration to another equal concentration
- Inside the cell to the nucleus
masalah 5
pilihan
Which statement about osmosis is correct?
- It moves water from a high to a low concentration through a partially permeable membrane.
- It moves solutes across a membrane.
- It requires energy.
- It moves only in one direction.

- It swells and bursts
- It shrinks
- It remains the same size
- It becomes turgid
masalah 7
pilihan
What will happen to a red blood cell placed in distilled water?
- It will shrink
- It will remain the same size
- It will burst
- It will divide
masalah 8
pilihan
What happens when a plant cell is placed in a hypertonic solution?
- It becomes turgid
- It undergoes plasmolysis
- It swells and bursts
- It becomes flaccid
masalah 9
pilihan
Why does a plant cell not burst when placed in a hypotonic solution?
- The cell wall prevents excessive expansion
- The plasma membrane becomes stronger
- The nucleus prevents water from entering
- The cytoplasm absorbs all the water

- It requires a transport protein
- It moves substances against the concentration gradient
masalah 12
pilihan

- Active Transport
masalah 13
pilihan
A cell is placed in a solution, and it shrinks. What can you conclude about the solution?
- It is hypotonic
- It is hypertonic
- It is isotonic
- It has no water
masalah 14
pilihan
Why do freshwater fish not drink water like saltwater fish?
- They do not need water to survive
- They gain water by osmosis and excrete excess water through urine
- They lose water to their surroundings
- They do not have a need for osmosis
