KSEEB Solutions For Class 9 Science Question 1.
What is tissue?
A group of cells that are similar in structure and for work together to achieve a particular function forms a tissue.
KSEEB Solutions For Class 9 Science Tissues Question 2.
What is the utility of tissues in multi-cellular organisms?
In human beings, muscle cells contract and relax to cause movement, nerve cells carry messages, blood flows to transport oxygen, food, hormones and waste material and so on. This is the utility of tissues in multi-cellular organisms.

KSEEB 9th Science Solutions Question 2.
How many types of elements together make up the xylem tissue? Name them.
Tracheids and vessels, xylem parenchyma and xylem fibre all these make up the xylem tissue.
KSEEB Solutions For 9th Class Science Question 3.
How are simple tissues different from complex tissues in plants?
Simple tissues are made of thin cell walls. Complex tissues are made of more than one type of cells.
9th Science Notes KSEEB Question 4.
Differentiate between parencyma, collenchyma and sclerenchyma on the basis of their cell wall.
|It consists of relatively unspecialised living, cells with thin cell walls. They are usually loosely packed.||The cells of this tissue are elongated and irregularly thickened at the corners. There is very little intercellular space.||The cells of this tissue are dead. They are long and narrow as the walls are thickened due|
KSEEB Solutions For 9 Science Question 5.
What are the functions of the stomata?
Stomata are necessary for exchanging gases with the atmosphere, transportation (loss of water in the form of water vapour) also takes place through stomata.
KSEEB Solutions For Science Class 9 Question 6.
Diagrammatically show the difference between the three types of muscle fibres.
Karnataka State Syllabus For Class 9 Science Notes Question 7.
What is the specific function of the cardiac muscle?
Cardiac muscles show rhythmic movement throughout our life. This movement helps blood to supply food and oxygen to all parts of our body.
KSEEB Solution For Class 9 Science Question 8.
Differentiate between striated, unstriated, and cardiac muscles on the basis of their structure and site/location in the body.

KSEEB Solutions 9 Science Question 10.
Name the following:
(a) Tissue that forms the inner lining of the cour mouth.
(b) Tissue that connects muscle to bone in humans.
(c) Tissue that transports food in plants.
(d) Tissue that stores fat in our body.
(e) Connective tissue with a fluid matrix.
(f) Tissue present in the brain.
(a) Epithelial tissue.
Identify the type of tissue in the following: skin, bark of tree, bone, lining of kidney tubule, vascular bundle.
- Skin: Areolar tissue.
- bark of tree: Epidermis tissue.
- bone: Tendon tissue.
- lining of kidney tubule: unstriped muscles.
- Vascular bundle: Xylem & Phloem.
Name the regions in which parenchyma tissue is present.
Roots and stems.
What is the role of the epidermis in plants?
- Epidermis of the leaf contains stomata. Stomata are enclosed by two kidney-shaped cells called guard cells. They are necessary for exchanging gases with the atmosphere.
- Transpiration (loss of water in the form of water vapour) also takes place through stomata.
How does the cork act as a protective tissue?
Cells of cork are dead and compactly arranged without intercellular spaces. They also have a chemical called suberin in the walls that makes them impervious to gases and water.
