By ConceptScroll Team · Published on 19 June 2026 · 3 min read
In Class 9 Science, 'what is tissues class 9 answer' refers to the basic definition of tissues as groups of similar cells performing a specific function. This chapter explains plant and animal tissues, helping you grasp essential biology concepts for your NCERT exams.
Definition of Tissues in Class 9 Science
Tissues are groups of cells that are similar in structure and work together to perform a specific function. In Class 9 NCERT Science, the chapter on Tissues introduces this fundamental biological concept.
- Cells are the basic units of life.
- When similar cells join, they form tissues.
- Tissues help organisms perform complex activities efficiently.
For example, muscle tissues in animals help in movement, while xylem tissue in plants helps in water conduction.
Types of Plant Tissues Explained
Plant tissues are mainly divided into two categories:
1. Meristematic Tissues
- Actively dividing cells
- Responsible for plant growth
- Found at root tips, shoot tips, and cambium
2. Permanent Tissues
- Derived from meristematic tissues
- Cells lose the ability to divide
- Types include:
- Parenchyma: Storage and photosynthesis
- Collenchyma: Provides flexible support
- Sclerenchyma: Provides rigid support
- Xylem: Conducts water and minerals
- Phloem: Transports food
Understanding these tissues helps you answer questions on plant structure and function.

Animal Tissues: Four Main Types and Their Functions
Animal tissues are classified into four main types:
| Tissue Type | Function | Example |
|---|---|---|
| Epithelial | Covers body surfaces and cavities | Skin, lining of mouth |
| Connective | Supports and connects body parts | Bone, blood, cartilage |
| Muscular | Enables movement | Skeletal muscles |
| Nervous | Transmits signals for coordination | Brain, spinal cord |
Each type has specialized cells working together to maintain the body's structure and function.
Comparison Between Plant and Animal Tissues
Here is a simple comparison to help you understand the differences:
| Feature | Plant Tissues | Animal Tissues |
|---|---|---|
| Cell Wall | Present (cellulose) | Absent |
| Types | Meristematic and Permanent | Epithelial, Connective, Muscular, Nervous |
| Function | Growth, support, transport | Protection, support, movement, coordination |
| Cell Shape | Usually fixed and regular | Variable |
This table helps clarify how plant and animal tissues differ structurally and functionally.
Worked Example: Identifying Tissue Types
Example: Identify the type of tissue in the following cases:
1. Tissue that transports food in plants. 2. Tissue that helps in body movement in animals.
Solution:
1. The tissue that transports food in plants is Phloem. 2. The tissue responsible for body movement in animals is Muscular tissue.
This example shows how to apply your knowledge of tissues to answer typical exam questions.
Importance of Studying Tissues for Class 9 NCERT Exams
The chapter on Tissues is crucial for your Class 9 Science exam because:
- It builds foundational knowledge for higher classes.
- Questions often include definitions, diagrams, and functions.
- Understanding tissues helps in learning plant and animal biology.
- It enhances your ability to observe and describe living organisms.
Make sure to revise all tissue types and their functions regularly, practice diagrams, and solve NCERT exercises for best results.
