Tissues MCQs with Answers & Explanations
Q1. What is a tissue?
- A group of different organs
- A single cell
- A type of cell membrane
- A group of similar cells performing a common function ✓ (correct)
Explanation: A tissue is a collection of similar cells that work together to perform one or more specific functions.
Q2. Which of the following is an animal tissue?
- Epithelial tissue ✓ (correct)
- Parenchyma
- Phloem
- Xylem
Explanation: Epithelial tissue covers the body surface and lines body cavities. Xylem and phloem are plant tissues, and parenchyma is a plant tissue type.
Q3. The tissue responsible for movement in animals is:
- Epithelial tissue
- Muscle tissue ✓ (correct)
- Nerve tissue
- Connective tissue
Explanation: Muscle tissue contracts and relaxes, enabling movement and maintaining posture in animals.
Q4. Which plant tissue transports water and minerals from roots to leaves?
- Sclerenchyma
- Parenchyma
- Xylem ✓ (correct)
- Phloem
Explanation: Xylem conducts water and dissolved mineral salts from the roots to the entire plant through a network of vessels and tracheids.
Q5. Nerve tissue is composed of:
- Muscle fibers
- Fibroblasts
- Epithelial cells
- Neurons and glial cells ✓ (correct)
Explanation: Nerve tissue consists of neurons (which transmit electrical signals) and glial cells (which support neurons).
Q6. Which of the following is a function of connective tissue?
- Support, binding, and insulation of organs ✓ (correct)
- Conduction of nerve impulses
- Absorption of nutrients
- Gas exchange
Explanation: Connective tissue provides structural support, binds tissues together, stores energy, and insulates the body.
Q7. The tissue that forms the outer layer of skin is:
- Connective tissue
- Epithelial tissue ✓ (correct)
- Muscular tissue
- Nervous tissue
Explanation: The epidermis (outer layer of skin) is composed of epithelial tissue that protects the underlying structures.
Q8. Which plant tissue stores food, water, and other substances?
- Xylem
- Collenchyma
- Parenchyma ✓ (correct)
- Sclerenchyma
Explanation: Parenchyma cells have thin walls, large vacuoles, and are primary storage tissue in plants.
Q9. The transport of food and other organic compounds in plants occurs through:
- Epidermis
- Cuticle
- Xylem
- Phloem ✓ (correct)
Explanation: Phloem transports sugars and other organic products from the leaves to all other parts of the plant.
Q10. Which type of muscle tissue is found in the heart?
- Skeletal muscle
- Cardiac muscle ✓ (correct)
- Smooth muscle
- All of the above
Explanation: Cardiac muscle is found in the heart and has striations and a single nucleus per cell, enabling coordinated contractions.
Frequently Asked Questions
What is the difference between simple and complex tissues?
Simple tissues consist of only one type of cell (e.g., parenchyma), while complex tissues are made of more than one type of cell working together (e.g., xylem and phloem in plants, or bone in animals).
Why do animals need different types of tissues?
Different tissues have specialized functions. Epithelial tissue protects, muscle tissue enables movement, nerve tissue transmits signals, and connective tissue provides support, allowing the organism to function as an integrated whole.
