B3

Question 1

Active transport

Answer 1

The movement of substances across the cell membrane against concentration gradient using respiration energy

Question 2

Osmosis

Answer 2

The movement of water molecules from a high concentration to a low concentration through a partially relieved permeable membrane and it is done within a concentration of water

Question 3

Diffusion

Answer 3

The net passive particle movement from high concentration to low concentration

Question 4

Transpiration

Answer 4

The process where water is transported from the roots to the leaves and results in evaporation at the Leaves

Question 5

Translocation

Answer 5

The movement of sugars through a plant

Question 6

Potometer

Answer 6

Apparatus which measures the rate of water

Question 7

Mitochondrion

Answer 7

Organelles that produce energy with respiration

Question 8

Vacuole

Answer 8

A large plant cell structure with watery sap and stores food or waste

Question 9

Turgid

Answer 9

Tissues in a plant that become firm as it gains water in osmosis

Question 10

Flaccid

Answer 10

Tissues in a plant are floppy as the plant lost water in osmosis

Question 11

Equilibrium

Answer 11

Estate in which there are equal amounts of particles on each side of the cell membrane

Question 12

Selectively permeable

Answer 12

Cell membranes that control what gets through

Question 13

Stomata

Answer 13

The pores found mostly on the lower surfaces of the leaves that allowed the entry and exit of gases and water vapour

Question 14

Passive

Answer 14

A process that does not require an input energy from respiration

Question 15

Vascular bundle

Answer 15

Plant tissue which contains the transport of cells called xylem and phloem

Question 16

Xylem

Answer 16

Plant cell involved in the transport of water and minerals

Question 17

Cellulose

Answer 17

A substance made by plants that form the structure of their cell walls

Question 18

Phloem

Answer 18

Plant cells involved in the transport of food, mainly sucrose

Question 19

Cell wall

Answer 19

A tough protective structure made of cellulose that surrounds the cell membrane in the plant cells

Question 20

Concentration gradient

Answer 20

The variation in concentration of a substance into different areas

Question 21

Plasmolysis

Answer 21

State of a cell when it is flaccid and the cell membrane has detached from the cell wall because the vacuole and cytoplasm have shrunken
