Weekly Quiz Competition

Question 1
1 / -0

The intrafascicular cambium:

A
Is a simple permanent tissue.

B
Is a meristematic tissue.

C
Is a complex permanent tissue.

D
Is secondary meristem.

Solution

Intrafascicular cambium is the primary meristem. It develops from the procambium of the stem apex. It is located inside the open vascular bundles between phloem and xylem patches. During secondary growth, the derivatives are only secondary phloem and secondary xylem.
So, the correct answer is option B.
Question 2
1 / -0

Chordae tendinae are the cord like structures that originate from papillary muscles of the inner border of the ventricles and are attached to free edges of the cuspid valves. What would happen if there is breakdown of chordae tendinae of bicuspid valves?

A
There will be regurgitation of blood into right atrium during ventricular systole

B
The bicuspid valves will not close

C
The blood may flow back into the left atrium during ventricular systole

D
There may be regurgitation of blood into both the atria during ventricular systole
Question 3
1 / -0

Which of the following statement is incorrect?

A
about $97$ percent of $O_2$ is transported by RBCs in blood

B
$20-25$ percent $CO_2$ is transported by RBCs

C
$70$ percent of $CO_2$ is carried as bicarbonates

D
$7$ percent of $O_2$ is carried in a dissolved state through plasma
Question 4
1 / -0

Which of the following cell/organism does not form pseudopodia during its movement/locomotion?

A
WBC

B
Sperm

C
Macrophage

D
Amoeba

Solution

Correct option: B.
Pseudopodia are temporary arm-like projections of the cytoplasm of a eukaryotic cell. WBC, macrophages and amoeba have pseudopodia. Sperm cells move due to changes in intercellular ion concentration and not by pseudopodia.
Question 5
1 / -0

Conduction of water and minerals is the main function of:

A
Stem

B
Phloem

C
Leaf

D
Xylem
Question 6
1 / -0

Which of the following are principal cells of areolar connective tissue and secrete maximum amount of matrix?

A
Mast cells

B
Fibroblast

C
Histiocyte

D
Macrophage
Solution
- Fibroblasts are the prominent cells of areolar tissue. They actively synthesize various components of the matrix including collagen.
- Mast cells release histamine and heparin during allergic reactions.
- Macrophages are phagocytic cells.
- Histiocytes are the macrophages present in tissues.
Hence the correct option is B.
Question 7
1 / -0

Transport of $CO_2$ is mainly in the form of

A
Sulphates

B
Phosphates

C
Bicarbonate

D
Chlorides

Solution

The correct answer is C.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods: dissolution directly into the blood, binding to hemoglobin, or carried as a Bicarbonate(Carbonate) ion. 70% of Carbon dioxide is transported as bicarbonates.
Question 8
1 / -0

The living component of xylem tissue is

A
Xylem vessel

B
Xylem parenchyma

C
Xylem tracheid

D
Xylem fibre

Solution

The xylem contains xylem vessel, xylem parenchyma, xylem tracheid and xylem fibers. Among these components, xylem tracheids, xylem vessels, and xylem fibers are dead components of xylem tissues because they are highly lignified and clarified. Xylem parenchyma is the living component of xylem tissue and helps in storage.
Hence, the correct answer is (B).
Question 9
1 / -0

Which option is correctly identifying the given formed elements?

A
A-RBC, E-Eosinophil

B
C-Eosinophil, G-B-lymphocyte

C
D-Basophil, F-Monocyte

D
B-Platelets, H- T-lymphocyte

Solution

The correct answer is D.
Platelets have no cell nucleus. They are fragments of cytoplasm that are derived from the megakaryocytes of the bone marrow, which then enter the circulation.
T-cell receptors consist of two polypeptide chains. A typical T cell may have as many as 20,000 receptor molecules on its membrane surface, all of either the alpha-beta or gamma-delta type. T-cell antigen receptor. The basic structure of a typical T-cell antigen receptor.
Question 10
1 / -0

Decrease in number of erythrocytes in blood is due to the deficiency of?

A
Cyanacobalamine

B
Folic acid

C
Ascrobic acid

D
Pyridoxine
