AP Board Class 9 Biology Chapter 2 Plant Tissues

AP Board Class 9 Biology Chapter 2 mainly discusses the topic of plant tissues. Besides, in this chapter, students will also recall the information about different parts of the plants and the functions they are associated with. The main aim or objective of this chapter though is to help students understand the different types of tissues present in plants and their functions.

What is a Tissue?

As per the general definition, a tissue is a group of cells having a similar structure and performing similar functions.

Different Types of Plant Tissues

Here we will look at the different types of plant tissues.

  1. Meristematic tissue is the dividing tissue, which is mostly present in the growing regions. Meristematic tissue is of three types, namely Apical meristem, Lateral meristem and Intercalary meristem.
  2. Ground tissue is bulk in all the parts of the plant and gives support and stores food. It is also of three types – Parenchyma, Collenchyma and Sclerenchyma.
  3. The dermal tissue is the tissue that protects the soft tissues of plants and controls interactions with the plants’ surroundings. The dermal tissue consists of epidermis and periderm.
  4. Vascular tissues are tissues involved in transportation. It mainly consists of xylem and phloem.

Students can go through some of the questions below and further understand about some of the important chapter topics.

Question 1: What is the main function of a dermal tissue?

Answer: Dermal tissue covers the plant body and gives protection.

Question 2: Write the differences between Apical meristem and lateral meristem


Apical meristem Lateral meristem
Apical meristem is the tissue found in the apex of roots and stems. Lateral meristem is the tissue that is found in the sides of stems and roots.
It gives rise to the xylem, phloem, epidermis, and ground tissue. Lateral meristem usually gives rise to inner and outer bark as well as wood.
It allows the plant to develop special structures like leaves and flowers. It allows the plant to grow taller and be more strong.
It generally occurs in all phyla of plants. It is not present in horsetails and mosses.

Question 3: Which tissue is responsible for bringing overall growth and repair.

Answer: The Meristematic tissues bring about overall growth and repair in plants.

Question 4: What are Vascular tissues?

Answer: Vascular tissues  are tissues that help with transport of materials.

Question 5: What does the dermal layer protect the plants from?

Answer: The dermal layer protects the plants from loss of water, mechanical damage and invasion by parasitic and disease causing organisms.
