Biology Form 5 KSSM Chapter 4 (Part 1)

Which of the following part labelled A, B, C and D is responsible for transporting water?

• A

• B

• C

• D

The following are the characteristic of xylem, EXCEPT

• The elongated cells are arranged end to end

• Forms root hairs that are not coated with cuticle

• Wall are thickened with lignin

__________ tissue is involved in transportation of organic substances

• Xylem

• Tracheid

• Epidermis

• Phloem

What is the function of tissue X?

• Stores food as starch

• Transport the products of photosynthesis

• Transport water and mineral salts

• Provides support to plant

Answer explanation

X is sieve tube

Both P and Q are the structure of phloem tissue. What is the function of P?

• Transport products of photosynthesis

• Supply energy (ATP) and essential materials for metabolism

• Stores food as starch

Answer explanation

P is companion cell. The function is to supply energy (ATP) and essential materials for metabolism (B). Q is sieve tube. The functions is to transport products of photosynthesis (A). The answer C is the function of fibre.

Factors below involved in the pathway of water and mineral from soil to leave, EXCEPT

• Transpiration pull

• Evaporation

• Capillary action

• Root pressure

In which part of the plant does the transpiration pull takes place?

• Root

• Stem

• Leaf

This figure show the movement of water into the root hair cells via osmosis. Which are the factors represent this figure?

• Transpiration pull

• Capillary action

• Root pressure

• Evaporation

What is guttation?

• When a plant dies due to excessive water in its tissues

• When a plant secretes excessive water in droplets through hydathode

• When a plant wilts due to lack of water in its tissues

• When a plant carries out transpiration through evaporation of water vapour

Which of the following is the CORRECT differences between transpiration and guttation?

• Transpiration happens at night or early morning while guttation happens during hot and windy day

• Guttation happens during dry condition while transpiration happens during humid condition

• Guttation secretes water that rich in minerals while transpiration secretes pure water only

• Transpiration occurs in herbaceous plant while guttation occurs in both herbaceous and terrestrial plant
