Multiple choice botany plant tissue system ground tissue system ground tissues tissue systems

Periblem gives rise to

  1. Epidermis

  2. Cortex

  3. Pericycle

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

Histogen theory by Hanstein states that shoot apical meristem consists of three distinct zones- 

i) Dermatogen (external layer), which form outer covering of all organ of plant. 
ii) Periblem (middle layer) gives rise to cortex and endodermis. 
iii) Plerome (central layer) form pith and primary vascular bundle. Thus, option B is correct.

Explanation

A.Endodermis - Inner most layer of cortex

B.Epidermis – outer layer of organs.

C.Exodermis – outer most layer of mature monocot root.

D.Hypodermis – it is present inner to the epidermis in stems.

So, the correct option is ‘Endodermis’.

Multiple choice biology multicellular structure: tissue defense mechanism in plants epidermal tissue system kinds of plant tissue permanent tissues and their types

Periblem gives rise to 

  1. Epidermis

  2. Cortex

  3. Pericycle

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

The apical meristematic tissue is continuously dividing tissue which mainly helps forms different specialized cells. Periblem is the histogen in plants that gives rise to the cortex. It does not give rise to the epidermis, pericycle, and the pith. It is the multilayered zone that lies beneath the dermatogen. The periblem cells divide into anticlinal and periclinal planes and give rise to cortex and endodermis. Pleurome gives rise to pericycle, vascular tissues, pith and medullary rays. Dermatogen gives rise to an epidermal layer of plant organs. 
Thus, the correct answer is option B.

Innermost layer of cortex is

  1. Endodermis

  2. Epidermis

  3. Exodermis

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

Epidermis is the outermost covering of the primary plant body and is mostly represented by a single layer of compactly arranged, barrel-shaped parenchyma cells that delimit cotex on outer side.  

The inner most layer of cortex forms endodermis, which has compactly arranged barrel shaped cells. 
The outer suberized sub-epidermal layer of cortex is exodermis, it has unthickened passage cells and is mostly present in roots. 
Hypodermis refers to 5-7 layers of cortical cells present just beneath the epidermis. It is present in leaves not in roots.
So, the correct answer is option A.

Multiple choice botany asexual and sexual reproduction in plants structure of male and female reproductive structures structure of ovule gynoecium

A nutritive inner region of integument is?

  1. Amphithecium

  2. Endothecium

  3. Endothelium

  4. Endostomium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
In some plants, which have unitegmic and tenuinucellate ovules, nucellus degenerates at an early stage of ovule development. In such cases, the innermost layer of the integument becomes specialized and forms a tissue around the embryo sac that performs the nutritive function for the embryo sac. This specialized tissue is called the Endothelium. Therefore, a nutritive inner region of the integument is Endothelium.
So, the correct answer is C
Multiple choice zoology musculo - skeleton system gait of animals basics of joints joints and type of joints skeleton, joints and muscles

Which one of the following membranes secretes a watery fluid that lubricates and cushions the joint ?

  1. Tendons

  2. Ligaments

  3. Cartilage

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

The synovial membrane is the membrane that lines the articular surfaces of the bones of the synovial joint. Its secretes a watery fluid that lubricates and cushions the joint. It reduces the friction during movement.

Tendon is a cord of strong fibrous collagen tissue that connects muscles to bones and doesn't secrete any fluid. 
The ligament is a band of flexible fibrous connective tissue that connects bone to bone and doesn't secret any fluid. 
Cartilage is a tough and flexible material that acts as a cushion between the bones of joints and doesn't secret any fluid. 
So the correct option is D.

Multiple choice biology transport in animals cardiac cycle heart, blood vessels and cardiac cycle human heart

'Bundle of His' is a part of which one of the following organs in humans?

  1. Pancreas

  2. Brain

  3. Heart

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

The bundle of His is a collection of heart muscle cells, specialized for electrical conduction, that transmits the electrical impulses from the AV node (located between the atria and the ventricles) to the Purkinje fibers, which provide electrical conduction to the ventricles.

Which one acts as physiological barrier to entry of microorganisms in human body

  1. Monocytes

  2. Skin

  3. Epithelium of urinogenital tract

  4. Tears
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Physiological barriers to the entry of microorganisms in the human body are tears in eyes, saliva in mouth and HCl in the stomach.
  • The enzymes lysozymes are found in tears and saliva inhibits the synthesis of peptidoglycan present in the cell wall of microorganisms especially eubacteria.
  • Hence Tears acts as the physiological barrier to entry of microorganisms in the human body.
  • So, the correct answer is 'Tears'.
Multiple choice biology windows of knowledge human tongue organ of taste tongue : the organ of taste

Taste receptors are present over 

  1. Taste buds

  2. Membrane

  3. Dermis

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Specific chemicals in solution pass into the taste bud through the taste pore to come in contact with the protein receptor sites on the microvilli of the gustatory receptor cells. The latter set up nerve impulses in the sensory nerve fibres. The nerve fibres transmit the impulses to the taste centre in the brain where the sensation of taste arises. The facial nerve serves the anterior two-thirds of the tongue, the glossopharyngeal nerve serves the posterior one-third of the tongue. Sweet taste is on the tip of the tongue, salt taste is on the sides and tips of the tongue, sour taste is on the sides of the tongue and bitter taste is on the base of the tongue. Therefore, the taste receptors are present over the taste buds for the sensation.
So, the correct answer is 'Taste buds'.
