TRANSPORT AND CIRCULATION

Question 1

Structuures that deliver water and substances throughout the plant body

Answer 1

TRANSPORT

Question 2

What does Cardiovascular System consists?

Answer 2

Heart, blood vessels and blood

Question 3

It carries food nutrients such as sugar and amuno acids FROM LEAVES TO STORAGE ORGANS AND GROWINGPART OF PLANTS
-movement (BIDIRECTIONAL)

Answer 3

PHLOEM VESSEL

Question 4

Movement from leaves to strorage organs and growing parts of plant

Answer 4

TRANSLOCATION

Question 5

• Carries water and mineral transport from ROOTS TO AERIAL PARTS OF PLANT
• one way ( Moves up the stem )

Answer 5

XYLEM VESSEL

Question 6

Movement of H20 from low to high concentration

Answer 6

OSMOSIS

Question 7

What are the fluid regulations in plants?

Answer 7

OSMOSIS
TRANSPIRATION
ADHESION-COHESION PROPERTY OF WATER
CAPILARY ACTION

Question 8

• pulls the water up the bodies of plants to travel to its parts.
• As the H20 evaporates, the negative pressure created, exerts a pulling force that pulls the water upwards

Answer 8

TRANSPIRATION

Question 9

• Allows H20 to move up to the plant
• as the water gets inside the xylem, it clings to the xylem tissue ( ADHESION occurs) and at the same time the water molecules stick to one another ( COHESION - Hydrogen Bonds). Forming huge water chain

Answer 9

ADHESION- COHESION PROPERTY OF WATER

Question 10

How does adhesion occur in ADHESION- COHESION PROPERTY OF WATER?

Answer 10

When the water gets inside the xylem and clings to the xylem tissue

Question 11

Movement of liquid across a solid surface which is caused by adhesion. The H20 climb up to its own because the adhere to the surface of the xylem tubes

Answer 11

CAPILLARY ACTION

Question 12

• Marine Invertebrates matches the high level of solute concentration (urea) in the sea to tge high concentration of solute in their blood for them to survive
• excretes chloride and sodium at MINIMAL RATE

Answer 12

AQUATIC ANIMALS

Question 13

• Their body is hypertonic as compared to their environment; water diffuse into the body of the fish
• excretes LARGE AMOUNT OF SODIUM AND CHLORIDE

Answer 13

FRESHWATER VERTEBRATES

Question 14

Their body fluids is regulated by EXCRETORY SYSTEM

- to reduce water loss, they live in mosit environment, develop impermeable covering and produced concentrated urine

Answer 14

TERRESTRIAL ANIMALS
