2. Osmosis

3. Active transport

4. Passive transport

Q.

Which of the following process needs the involvement of energy?

4. Diffusion

Q.

Most of the mineral salts in the soil enter roots by the process of:

1. diffusion

2. osmosis

3. active transport

4. respiration

Q.

Diffusion occurs when molecules move:

1. From lower concentration to higher concentration.

2. From higher concentration to lower concentration through a membrane.

3. From higher concentration to lower concentration.

4. When energy is used.

Q. is the passage of a substance from its lower to higher concentration, using energy from the cell.

1. Diffusion
2. Osmosis
3. Facilitated diffusion
4. Active transport

Q.

Which pancreatic enzyme is effective in digesting proteins?

Q.

What are examples of passive transport?

Q. Active transport across cell membrane requires

1. Glucose
2. Energy in the form ATP
3. Steroids
4. Proteins and glucose

Q.

Differentiate between the following:
