Question 1

What are the parts of a cell (3)

Answer 1

Plasma membrane, cytoplasm, nucleus

Question 2

How does passive transport take places in cell membrane

Answer 2

Simple diffusion, osmosis for water molecules and facilitated diffusion through proteins (channel/ carrier)

Question 3

What happens if a cell is put into hypotonic solution

Answer 3

Water moves into the cell, the cell will swell

Hypotonic solution has lower solute concentration , water passes from high water concentration to lower water concentration .

Question 4

What are the examples of active transport? Which protein is involved in ?

Answer 4

Primary active transport through carrier protein (pump)
Secondary active transport through carrier protein

Endocytosis through receptor protein (binding with ligand)
Phagocytosis (no protein involved)
Exocytosis (no protein involved)

Question 5

Types of protein on cell membranes

Answer 5

Ion channels, carrier protein, receptor protein, enzymes, cell-identifying markers, linkers
