Summary of the Chapter-6-Tissues with Key-Points:
- A tissue is a collection of cells that share similar structure and function.
- In plants, there are two primary types of tissues: meristematic and permanent.
- Meristematic tissue consists of cells that divide and are found in the plant's growing regions.
- Permanent tissue originates from meristematic tissue once the cells stop dividing, and is divided into simple and complex tissues.
- Simple tissues include parenchyma, collenchyma, and sclerenchyma, while complex tissues include xylem and phloem.
- Animal tissues are categorized into epithelial, connective, muscular, and nervous tissues.
- Epithelial tissue is further classified based on shape and function into squamous, cuboidal, columnar, ciliated, and glandular types.
- The various types of connective tissues in the human body include areolar tissue, adipose tissue, bone, tendons, ligaments, cartilage, and blood.
- Muscle tissue is categorized into three types: striated, unstriated, and cardiac.
- Nervous tissue consists of neurons, which are responsible for receiving and transmitting impulses.
NCERT Based MCQ with Explanation:
1. What is the main function of meristematic tissue in plants?
(a) To provide structural support
(b) To conduct water and nutrients
(c) To divide and form new cells
(d) To protect against water loss
Explanation: Meristematic tissue is responsible for the growth of plants. These tissues are found in the growing regions such as the tips of roots and shoots, and their primary function is to divide and form new cells.
2. Which type of tissue is responsible for transporting water in plants?
(a) Phloem
(b) Xylem
(c) Parenchyma
(d) Collenchyma
Explanation: Xylem is a complex permanent tissue that transports water and dissolved minerals from the roots to other parts of the plant.
3. Which tissue in animals provides a barrier and covers the surface of organs?
(a) Epithelial tissue
(b) Muscle tissue
(c) Nervous tissue
(d) Connective tissue
Explanation: Epithelial tissue forms a protective layer over organs and cavities in the body, acting as a barrier to protect underlying tissues from damage, dehydration, and infection.
4. What type of plant tissue allows bending and flexibility in the plant?
(a) Parenchyma
(b) Collenchyma
(c) Sclerenchyma
(d) Meristematic tissue
Explanation: Collenchyma tissue provides flexibility and mechanical support to plants. It allows bending in plant parts like stems and tendrils without breaking.
5. Which of the following is a characteristic of cardiac muscle tissue?
(a) Multinucleate and voluntary
(b) Cylindrical and unbranched
(c) Striated and involuntary
(d) Spindle-shaped and voluntary
Explanation: Cardiac muscles are striated like skeletal muscles, but they are involuntary as they contract rhythmically without conscious control.
6. Which of the following tissue types is dead at maturity in plants?
(a) Parenchyma
(b) Sclerenchyma
(c) Collenchyma
(d) Xylem vessels
Explanation: Sclerenchyma cells are dead at maturity and provide mechanical strength due to their thickened lignin walls.
7. What is the function of stomata in plant epidermis?
(a) Transport of nutrients
(b) Gas exchange and transpiration
(c) Storage of food
(d) Support to the plant structure
Explanation: Stomata are small pores in the epidermis of leaves that regulate gas exchange and water vapor loss (transpiration).
8. In animals, what tissue type is responsible for transmitting impulses throughout the body?
(a) Muscle tissue
(b) Epithelial tissue
(c) Connective tissue
(d) Nervous tissue
Explanation: Nervous tissue is specialized for the conduction of nerve impulses, which allow communication between different parts of the body.
9. Which connective tissue stores fat in animals?
(a) Adipose tissue
(b) Areolar tissue
(c) Blood
(d) Bone
Explanation: Adipose tissue is a type of connective tissue that stores fat, which provides insulation and energy reserves for the body.
10. What is the role of the epidermis in plants?
(a) Conducting food
(b) Supporting the plant
(c) Protecting the plant and reducing water loss
(d) Transporting water
Explanation: The epidermis in plants serves as a protective barrier and helps to minimize water loss through the secretion of a waxy cuticle.
11. What type of cells make up the vascular bundle in plants?
(a) Parenchyma and Sclerenchyma
(b) Xylem and Phloem
(c) Epidermis and Collenchyma
(d) Meristematic and Parenchyma
Explanation: The vascular bundle is composed of xylem and phloem, which are responsible for conducting water, nutrients, and food throughout the plant.
12. Which plant tissue contains air spaces to help aquatic plants float?
(a) Collenchyma
(b) Parenchyma
(c) Aerenchyma
(d) Sclerenchyma
Explanation: Aerenchyma is a specialized form of parenchyma tissue that contains large air spaces, which help aquatic plants float and exchange gases.
13. In which region of a plant would you typically find apical meristem?
(a) At the tips of roots and shoots
(b) At the base of leaves
(c) In the middle of the stem
(d) In the leaves
Explanation: Apical meristem is located at the tips of roots and shoots and is responsible for the lengthwise growth of plants.
14. Which of the following tissues forms the outer covering of a young plant stem?
(a) Xylem
(b) Phloem
(c) Epidermis
(d) Collenchyma
Explanation: The epidermis is the outermost layer of cells that forms the protective covering of young plant stems, roots, and leaves.
15. What type of animal tissue is responsible for connecting bones to other bones?
(a) Tendon
(b) Cartilage
(c) Ligament
(d) Areolar tissue
Explanation: Ligaments are connective tissues that connect bones to other bones at joints, providing stability and flexibility.
16. Which of the following is not a type of simple permanent tissue in plants?
(a) Parenchyma
(b) Sclerenchyma
(c) Phloem
(d) Collenchyma
Explanation: Phloem is a type of complex tissue, as it is made up of more than one type of cell, unlike simple permanent tissues like parenchyma, sclerenchyma, and collenchyma.
17. Which of the following cells help in the clotting of blood?
(a) Red blood cells
(b) White blood cells
(c) Platelets
(d) Plasma
Explanation: Platelets are responsible for blood clotting, which prevents excessive blood loss when blood vessels are injured.
18. Which of the following tissues is responsible for conducting food in plants?
(a) Xylem
(b) Phloem
(c) Parenchyma
(d) Collenchyma
Explanation: Phloem is the vascular tissue that transports food, primarily sugars, from the leaves to other parts of the plant.
19. What is the function of intercalary meristem in plants?
(a) Increase in thickness of the plant
(b) Increase in length at the nodes
(c) Healing of wounds
(d) Protection of plant organs
Explanation: Intercalary meristem is located at the nodes and is responsible for the growth in length of certain parts of plants such as stems and leaves.
20. What type of muscle tissue is found in the walls of internal organs like the stomach?
(a) Cardiac muscle
(b) Striated muscle
(c) Smooth muscle
(d) Skeletal muscle
Explanation: Smooth muscles are involuntary muscles found in the walls of internal organs, and they help in processes such as digestion by contracting without conscious control.
