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

Casparian strip is found in

  1. Epidermis

  2. Endodermis

  3. Endothecium

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

Casparian strip is a band of cell wall material deposited on the radial and transverse walls of the endodermis and is chemically different from the rest of the cell wall. The cell wall being made of lignin and without suberin, whereas the Casparian strip is made of suberin and sometimes lignin. It blocks the passive flow of materials, such as water and solutes into the stele of a plant.

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

The endodermis is the central, innermost layer of cortex in some land plants. It is made of compact living cells surrounded by an outer ring of endodermal cells that are impregnated with hydrophobic substances (Casparian strip) to restrict apoplastic flow of water to the inside. The endodermis is the boundary between the cortex and the stele. 

The epidermis cells is a single-layered group of cells that covers plants leaves, flowers, roots and stems. It forms a boundary between the plant and the external environment. 
The exodermis is a layer of cells from the outermost layer of the cortex of many angiosperms. 
Hypodermis is the outermost cell layer of the cortex of plants. It is also known as exodermis.

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.

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

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.

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

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.

'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.

Blood is not a tissue because it is a fluid

  1. True

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

Blood is considered a connective tissue due to two basic reasons: (1) Embryologically, it has the same origin (mesodermal) as other connective tissues (2) Blood connects the body systems together and transports the required oxygen, nutrients, hormones and other signaling molecules, and removes the wastes. 
So, the correct answer is option B.

Multiple choice biology animal tissue muscle tissue structure of protein muscle tissues

All the following are examples of connective tissue except _______________.

  1. Tendons

  2. Ligaments

  3. Muscle

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

Connective tissue serves a connecting function. It supports and binds other tissues in the body. This tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. The primary elements of connective tissue include a ground substance, fibres, and cells. Adipose tissue is a type of specialised connective tissue and the ligaments and the tendons belong to the dense type of connective tissue while the muscle belongs to another class of tissues namely muscle tissue which are different from the connective tissue.
So, the correct answer is 'Muscle'.
