FAQs on L2 - Plant Tissues - Tissue, Class 9, Science

Question 1

1. What are plant tissues?

Accepted Answer

Ans. Plant tissues are groups of cells that work together to perform specific functions in a plant. They are classified into two main types: meristematic tissues and permanent tissues.

Question 2

2. What is the function of meristematic tissues?

Accepted Answer

Ans. Meristematic tissues are responsible for the growth and development of plants. They are located at the tips of roots and shoots and promote cell division, leading to an increase in the length and girth of the plant.

Question 3

3. What are the different types of permanent tissues in plants?

Accepted Answer

Ans. There are three types of permanent tissues in plants: simple permanent tissues, complex permanent tissues, and secretory tissues. Simple permanent tissues include parenchyma, collenchyma, and sclerenchyma, while complex permanent tissues include xylem and phloem.

Question 4

4. What is the role of xylem and phloem in plants?

Accepted Answer

Ans. Xylem is responsible for the transport of water and minerals from the roots to the other parts of the plant. Phloem, on the other hand, transports organic nutrients, such as sugars, from the leaves to the rest of the plant.

Question 5

5. How does the arrangement of cells in plant tissues differ?

Accepted Answer

Ans. The arrangement of cells in plant tissues varies depending on their function. For example, parenchyma cells are loosely packed and have thin cell walls, allowing for photosynthesis and storage of nutrients. On the other hand, sclerenchyma cells have thick cell walls with lignin, providing strength and support to the plant.
