TKC Biology KSSM FORM 5 CHAPTER 1 & 2

Front

What is secondary growth in plants?

Back

Secondary growth is the increase in thickness or girth of a plant, primarily due to the activity of lateral meristems.

Front

What is the main function of the cuticle in a leaf?

Back

The main function of the cuticle is to reduce water loss from the leaf surface.

Front

Which factors affect transpiration rate?

Back

Factors affecting transpiration rate include temperature, humidity, and wind speed. Root length does not affect transpiration rate.

Front

What type of plant tissue is responsible for the transport of water?

Back

Xylem is the type of plant tissue responsible for the transport of water.

Front

What type of plant growth results in an increase in height?

Back

Primary growth results in an increase in height of the plant.

Front

Define apical meristem.

Back

Apical meristem is a type of meristem located at the tips of roots and shoots, responsible for primary growth.

Front

What is the role of lateral meristem?

Back

Lateral meristem is responsible for secondary growth, increasing the thickness of stems and roots.

Front

Explain the process of transpiration.

Back

Transpiration is the process by which water vapor is lost from the aerial parts of plants, primarily through stomata.

Front

What is the function of phloem?

Back

Phloem is responsible for the transport of nutrients and food (sugars) produced by photosynthesis.

Front

What is the significance of intercalary meristem?

Back

Intercalary meristem allows for growth in length at the base of leaves and internodes, particularly in grasses.
