Concept Check 1  (Page 25)

Answer the following questions.

Question 1:

What is a tissue ?

Answer :

Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others.

Question 2:

How are plant tissue broadly classified ?

Answer :

In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue

Question 3:

Where is apical meristem found ?

Answer :

Apical meristems, which are located at the tips of shoots and roots in all vascular plants, give rise to three types of primary meristems, which in turn produce the mature primary tissues of the plant

Question 4:

Which meristem is responsible for the increase in girth of a plant ?

Answer :

Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.

Question 5:

Why are sclerenchyma cells so hard ?

Answer :

Cells of sclerenchyma have a tough protein called lignin in their cell walls this give structural strength to them all the cells of sclerenchyma tissues are dead this is the reason they are hard

Question 6:

Name the tissue that provides the up word movement of water and mineral salts in plant body.

Answer :

Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.

B. Short Answer Type Questions,  (Page 36)

Question 1:

Give one function each of the following:

(a) Blood and lymph

Answer:

Both are two circulatory fluids of the body, Blood moves via blood vessels and lymph moves via lymphatic vessels. Blood transports gases, nutrients, and metabolic wastes. Lymph is draining of tissue fluid into the circulatory system. The major difference between blood and lymph is their function in the body.

(b) Tendon and ligament

Answer:

A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable

(c) Cardiac muscle fibres

Answer:

Only present in hear, it contracts and allows the heart to pump blood into the body organs.

(d) Xylem

Answer:

Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

(e) Meristem

Answer:

Meristem, region of cells capable of division and growth in plants.

Question 2:

Give differences between the following :

(a) Chlorenchyma and aerenchym

Answer:

The main difference between chlorenchyma and paerenchyma is that chlorenchyma is a form of parenchyma, containing chloroplasts, but aerenchyma is another form of parenchyma, containing large air spaces. Generally, parenchyma is a form of ground tissue with living cells, having primary cell walls

(b) Tracheid and vessel

Answer:

Tracheids and vessels are the two water conducting elements found in the xylem. Tracheids are the major conducting element in ferns and gymnosperms. Vessels are only present in angiosperms. … The main difference between tracheids and vessels is their diameter and the efficiency in water

(c) Blood and lymph

Answer:

Blood has RBC’s, WBC’s, platelets and a fluid called plasma. Whereas lymph has WBC’s and watery fluid. They both have immune and also circulatory functions in them. One of the major differences between them is that blood flows through blood vessels and lymph through lymphatic vessels

(d) Bone and cartilage

Answer:

Bones	Cartilage
The matrix is both organic and inorganic.	The matrix is completely organic.
Has deposits of calcium salts.	May or may not have deposition of calcium salts.
The bones have a rich blood supply.	Lacks blood supply (hence repair is slower)

(e) Tendon and ligament

Answer

The most apparent difference between ligaments and tendons is that tendons join bone to a skeletal muscle and ligaments join bone to another bone. Tendons are strong and non-flexible while ligaments are flexible and elastic. Both play a vital role in joints and bones and are composed of living cells

(f) Meristematic and permanent tissues

Answer:

Meristematic tissue has cells small in size and isodiametric in shape. Permanent tissue has cells large in size and their shape varies. Cells are compactly arranged without having intercellular spaces. Cells are arranged loosely in the parenchyma and compactly in sclerenchyma
