• True

• False

Genetic Diversity in an ecosystem does not affect biodiversity in any way.

• True

• False

What is the function of the stomata?

• to perform photosynthesis

• to produce sugar

• to allow water into the leaf

• to enable gases to enter and leave

Non-vascular plant mean

• They have no phloem and xylem

• They have phloem and xylem

• Algae

• Mosses

• Fern

• Gymnosperms

• Angiosperms

Which of the following produce seed?

• Algae

What causes this plant to be epiphytic ?

• This plant traps its prey

• This plant synthesises its food by absorbing nutrient from host

• This plant lives on other plants that is taller

• This plant live in areas that is low in nitrogen and obtain nitrogen from the prey.

Diagram shows two types of plant X and Y. Which of the following differences is true between plant X and Y?

• X is a parasitic plant while Y is a carnivorous plant

• X absorbs nutrients from its host while Y produce food through photosynthesis

• X does not give harm to its host while Y does give harm to its host

• X traps insects to obtain the nitrogen supply while Y live on the host to obtain the sunlight supply

Diagram shows a type of plant.

How do this plant gets its nutrients?

• This plant traps insects for nutrient supply

• This plant lives on other plants namely the host

• The roots of the plant absorb organic materials, minerals and water from its host.

• The roots of the plant can absorb the nutrients that accumulate in the gaps of the host stems.
