Melanin pigment of human skin is produced by

  1. Mast cells of corium

  2. Melanocytes of corium and incorporated there

  3. Melanocytes of corium and incorporated in epidermis

  4. Melanocytes of epidermis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Melanin is a pigment produced within the skin in melanocytes or skin cells when they are exposed to the sun. 
  • The process by which the pigment melanin is formed by the melanocytes is called melanogenesis.
  • The pigment is formed within a small membrane-bound structure called melanosomes.
  • The skin colour is determined by a bluish-white connective tissue under the dermis or corium and the haemoglobin circulating in the veins of the corium.
  • The corium is a layer of skin present between the epidermis and the subcutaneous tissues of the skin.
  • Two types of melanin are formed in the body pheomelanin (red to yellow in colour) and eumelanin (dark brown to black).
  • Those people with light complexion produce pheomelanin whereas, those with dark complexion produce eumelanin.
  • So, the correct answer is 'Melanocytes of corium and incorporated in epidermis'.
Multiple choice biology multicellular structure: tissue defense mechanism in plants epidermal tissue system kinds of plant tissue permanent tissues and their types

Choose the odd feature for epidermis

  1. Living

  2. Parenchymatous

  3. Always single layered

  4. May have cutin deposition
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Epidermis usually consists of a single layer of cells and is the outermost layer present on leaves, stem and roots of plants. The epidermis consists of living parenchyma cells. On most plant stem and leaves, cutin, a fatty substance, is very often deposited on the outer surface of the epidermal cell wall to form cuticle over which wax may also be deposited. Generally epidermis is single layered, but in xerophytes it is multilayered'

So, the correct option is 'always single layered'.

Cuticle is secreted by

  1. Epidermis

  2. Endodermis

  3. Both A and B

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

Epidermis is the part of epidermal tissue system and forms the outer protective covering of primary plant body. The epidermal cells secrete cutin, which is a hydrophobic substance and prevents water loss and desiccation. The cutin forms a covering outside the epidermal cells in all plants parts except root.

The innermost layer of cortex forms endodermis, which has compactly arranged barrel shaped cells. The primary thin walled endodermis shows suberin deposition in form of bands or strips that run around the radial and end walls of the cells and forms Casparian strips. 
Hypodermis refers to 5-7 layers of cortical cells present just beneath the epidermis.

The term periderm is used to include

  1. Cortex

  2. Secondary cortex

  3. Both of the above

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The periderm is the secondary protective dermal tissue that replaces the epidermis during growth in thickness of stems and roots of gymnosperms and dicotyledons i.e., secondary growth. 

Unlike typical epidermis, the periderm is a multilayered tissue system, the bulk of which usually constitutes the cork or phellem. It has cortex, secondary cortex.

______ has glandular hair.

  1. <p>Calotropis</p>

  2. Tobacco

  3. Lemon

  4. <p>Yucca</p>
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are various defense mechanism seen in plants. These are thorns, spines, prickles, glandular hair, stinging hair, alkaloids, tannins, raphides, etc. Tobacco has glandular hair for its defense. Glandular hair with sticky substances protect it from outer agencies. Lemon has thorns to protect itself from its enemies. Yucca has pointed spines at the leaf ends to protect itself from enemies.
Calotropis is known as milkweeds because of the latex they produce. Thus, the correct answer is 'Tobacco.'

Multiple choice biology plant and animal tissues nervous system in animals structure of neuron structure and function of neuron

Pigmented dendritic cells occur in

  1. Stratum Malpighii

  2. Stratum granulosum

  3. Stratum corneum

  4. Stratum lucidum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Epidermis is the outer part of skin, which is keratinised and composed of stratified squamous epithelium layers. In the structure of epidermis on the basis of shape of cells and cytoplasm, there are five stratum -
(1) Stratum Malpighii
(2) Stratum spinosum
(3) Stratum granulosum
(4) Stratum lucidum
(5) Stratum corneum
An innermost stratum of epidermis consisting of one layer of cells is called as stratum Malpighii. It is also called as stratum basale. Cells are cubical or columnar in shape. In this stratum two types of cells are present.

(i) Melanocytes - They are called pigmented dendritic cell. These cells are formed by modification of cell which lies at the junction of epidermis and dermis. 
(ii) Keratinocytes - They get their nutrition from underlying connective tissue of dermis and divide to form another stratum of the epidermis.

A change in a wart or mole on the skin is observed in

  1. Adenoma

  2. Carcinoma

  3. Lymphoma

  4. Melanoma
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Melanoma, also known as malignant melanoma is a type of cancer that develops from the pigment-containing cells known as melanocytes. Melanomas typically occur in the skin, but may rarely occur in the mouth, intestines, or eye. Sometimes they develop from changes in wart or mole such as an increase in size, irregular edges, change in colour, itchiness, or skin breakdown.

So, the correct answer is 'Melanoma'.
