Science M.C.Q-[Bio-1M]

3. Bone

Explanation:

Ligament is a dense connective tissue which connects a bone with bone.

1. Monocytes

Explanation:

Monocytes are largest blood cells. These are white blood cells.

3. Cardiac muscle.

Explanation:

Cardiac muscle fibre contains intercalated discs.

1. Sclerenchymatous tissue.

Explanation:

Husk of a coconut is made up of sclerenchymatous fibres.

4. Involuntary, striated and uninucleate.

Explanation:

Cardiac muscle fibres are branched, striated and uninucleate. These muscles are involuntary. These muscles are exclusively present in the heart and show rhythmic contraction and relaxation throughout life.

3. Bone.

Explanation:

Haversian canals are present in bone.

3. Stomata.

Explanation:

Each stomata is surrounded by a pair of guard cells. Guard cells regulate the opening and closing of stomata.

1. Sclereids

Explanation:

The grit of pear is formed of stone cells also known as sclereids.

3. Intercalary meristem.

Explanation:

Intercalary meriste is commonly present at the base of the leaves or internodes (on either side of the node). The intercalary meristem increses the internode length, hence the stem elongates.

1. Plasma

Explanation:

Blood consists of plasma and blood corpuscles. Plasma is a liquid part of blood which contains 85-90% water.

2. Bichat

Explanation:

Bichat is also known as “Father of histology”.

3. Basement membrane.

Explanation:

Epithelial tissue always has an exposed outer surface and an inner surface anchored to connective tissue by a thin, non-cellular structure called the basement membrane.

4. Striated muscle fibres.

Explanation:

Under the microscope, striated muscles show alternate light and dark bands or striations when stained appropriately. As a result, they are also called striated muscles.

4. All the above.

Explanation:

It is composed of a single layer of cube-like cells. It is found in kidney tubules and salivary glands. It provides mechanical support to organs and helps in absorption and excretion.

4. Inner cortex.

Explanation:

The collenchyma is found in few layers below the epidermis of plant. It is generally absent in monocot stems and leaves. The cell wall is unevenly thickened.

1. Hypodermis

Explanation:

Collenchyma tissue are found below epidermis in leaves and stem.

4. All the above

Explanation:

Cardiac muscle fibres are branched, striated and involuntary. These muscles are exclusively present in the heart.

2. Small intestine.

Explanation:

It is composed of a single layer of tall and slender cells. Their nuclei are located at the base. Free surface may have microvilli. It is generaly found in the lining of stomach and intestine and help in secretion and absorption.

4. Adipose tissue.

Explanation:

A dipose tissue is fat storing connective tissue which is found mainly beneath the skin. Blubber of whale and hump of camel are adipose tissue which store fat.

4. All the three.

Explanation:

Areolar connective tissue is found between the skin and muscles, around blood vessels and nerves and in the bone marrow. It fills the space inside the organs, supports internal organs and helps in repair of tissues.

1. Tissue

Explanation:

A group of cells that are similar in structure and/ or work together to achieve a particular function forms a tissue.

4. Cambium.

Explanation:

Active divisions take place in the cells of cambium. Cambium is a meristematic tissue.
