Mammary glands are a part of 

  1. Epithelial tissue

  2. Connective tissue

  3. Skeletal tissue

  4. Muscular tissue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mammary glands are a modification of the epithelial layer or epithelial tissue. They are formed of the glandular epithelium.

So, the correct option is 'Epithelial tissue'.

The epithelium which forms the inner wall of blood vessels is_____________

  1. Cuboidal epithelium

  2. Ciliated epithelium

  3. Squamous epithelium

  4. Compound epithelium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The simple squamous epithelium that lines the blood vessels is called the endothelium. The endothelium is the thin layer of cells that line the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. Endothelial cells line the entire circulatory system, from the heart to the smallest capillary. These cells reduce turbulence of the flow of blood allowing the fluid to be pumped farther. 
Endothelial tissue is a specialized type of epithelium tissue (one of the four types of biological tissue in animals). More specifically, it is a simple squamous epithelium.

The covering tissue of external and internal surfaces of animal body is

  1. Connective

  2. Epithelial

  3. Muscular

  4. Areolar
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The external surfaces and internal linings of the animal body are made up of various kinds of epithelial tissues. Epithelial tissues have various functions all across our bodies like secretion, absorption, protection, sensing and, to some extent, thermoregulation. So, the correct answer is 'Epithelial'.

Specialized epidermal cells seen around the stomata are___________

  1. Lenticels

  2. Bulliform cells

  3. Guard cells

  4. Subsidiary cells
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. 
  • Lenticels are one of many raised pores in the stem of a woody plant that allows gas exchange between the atmosphere and the internal tissues. Bulliform cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many grasses. Loss of turgor pressure in these cells causes leaves to "roll-up" during water stress. 
  • Subsidiary cell is a plant epidermal cell that is located next to a guard cell in the stoma of a leaf and differs in structure from other epidermal cells. Also called an accessory cell.


Therefore, the correct answer is option C.

State whether true or false. 

The epidermal layer in plants does not have intercellular spaces. 

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The epidermis is the outermost cellular layer which covers the whole plant structure, i.e., it covers roots, stem, leaves, flowers and fruit. It is composed of a single layer of living cells, although there are exceptions. The epidermis is usually closely packed, without intercellular spaces or chloroplasts.

The epidermal cells provide ............ to the plants.

  1. Water

  2. Protection

  3. Strength

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The epidermis is the outermost cellular layer which covers the whole plant structure, i.e., it covers roots, stem, leaves, flowers and fruit. It is composed of a single layer of living cells, although there are exceptions. The function of epidermal cells are as follows-

1) The epidermal cells protect the underlying cells.
2) The waxy cuticle prevents the loss of moisture from the leaves and stems.
3) The transparent epidermal cells allow sunlight (for photosynthesis) to pass through to the chloroplasts in the mesophyll tissue.
4) The stomata of leaves and stems allow gaseous exchange to take place which is necessary for photosynthesis and respiration.
5) Water vapor may be given off through the stomata during transpiration.
6) The root-hairs absorb water and dissolved ions from the soil.

Promeristem is found in

  1. Embryo

  2. Root apex

  3. Shoot apex

  4. Intercalary region
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Promeristem are groups of meristematic cells found in germinating embryos or young seedlings. They give rise to primary meristems which initiate the organ formation process. Promeristems are also referred as primordial meristems or embryonic meristems because of their origin.
Thus, the correct answer is option A.

Dermal tissue is derived from

  1. Periblem

  2. Dermatogen

  3. Procambium

  4. Pleurome
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dermatogen is also known as protoderm which further divides to form the three dermal layer which is epidermis, endodermis and hypodermis. These form the protective layer of the plant. Epidermis is the outer layer which mainly bears small opening known as stomata.
Therefore, the correct answer is option B.

Muscular tissues which function throughout the life continuously without fatigue is______________

  1. Skeletal muscle

  2. Smooth muscle

  3. Cardiac muscle

  4. Voluntary muscle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. 
  • This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. 
  • Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e., conduct electricity), like the neurons that constitute nerves.
  •  Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. Cardiac muscle is adapted to be highly resistant to fatigue:
  •  it has a large number of mitochondria, enabling continuous aerobic respiration, numerous myoglobins (oxygen-storing pigment), and a good blood supply, which provides nutrients and oxygen.
