Weekly Quiz Competition

Question 1
1 / -0

The water conducting tissue generally present in gymnosperm is____________.

A
Vessels

B
Sieve tube

C
Tracheids

D
Xylem fibres

Solution

Gymnosperms do not have vessels in their xylem. Water conducting tissues present in them are tracheids. Hence the correct option is C.
Question 2
1 / -0

Difference between voluntary and involuntary muscles is

A
Voluntary muscles can be moved by conscious will while involuntary muscles function on their own.

B
Voluntary muscles are muscles of limbs or skeletal muscles while involuntary muscles are cardiac muscles and smooth muscles.

C
Both A and B

D
Voluntary muscles are control the function of heart and involuntary muscles controls the movement of arms.
Solution
- Muscle tissue is made up of elongated muscle fibres. Muscles that are under the control of our will are voluntary muscles. Such muscles are attached to bones hence, called skeletal muscles. These muscles help in body movement. These muscles, when stained, show alternate light and dark bands under the microscope. Therefore, also called striated muscles.
- Muscles, which are not controlled by our will are involuntary muscles. These muscles do not show striations when stained. Hence, called smooth muscles. Cardiac muscle is also a special type of muscle, which is involuntary. The function of the heart is under involuntary muscles.
- So, the correct answer is option C.
Question 3
1 / -0

The muscle type which functions throughout life continuously without fatigue is_____________________.

A
Skeletal muscle

B
Cardiac muscle

C
Smooth muscle

D
All of the above

Solution

Cardiac muscle can function without fatigue and with efficiency throughout life in an individual by themselves.
So, the correct answer is option B.
Question 4
1 / -0

In a neuron, conversion of electrical signal to a chemical signal occurs at

A
Cell body

B
Axonal end

C
Dendritic end

D
Axon

Solution

Signals are transferred from one neuron to another. The electrical signals are very fast as compared to that of chemical signals. Myelinated sheath present on the surface of neurons helps in better conduction of signals. At the end of the axon (axonal end), the electrical signal is converted into a chemical signal, and the axon releases chemical messengers called neurotransmitters (acetylcholine) which are received by their receptors on the dendrites of the subsequent neuron. This region is called synapse.
So, the correct answer is 'Axonal end'
Question 5
1 / -0

Which of the following cells contain the same kind of cell as shown in the figure given below?

A
A sperm cell

B
A cheek cell

C
A nerve cell

D
A blood cell

Solution

The given image represents the cheek cell. It is a squamous epithelial cell in which there is a cell membrane, which acts as the outer protective covering. There is a single nucleus at the center and there is dense cytoplasm.
Thus, the correct answer is option B.
Question 6
1 / -0

Which of the following types of tissues support, defend and store food in the body?

A
Epithelial tissue

B
Nervous tissue

C
Muscular tissue

D
Connective tissue

Solution

Blood, bone, tendon, cartilage, ligament, areolar tissue and adipose tissue are various types of connective tissue. Blood is a fluid connective tissue that consists of WBCs that form the body's immune system. Bone, cartilage, tendon and ligament have supportive functions while the areolar tissue supports internal organs and helps in their repair. Adipose tissues store food and fats.
Thus, the correct answer is option D.
Question 7
1 / -0

Which of the following are found in the blood but not in the lymph?
P - Lymphocytes
Q - Erythrocytes
R - Platelets
S - Plasma proteins

A
P, Q, and R only

B
P, Q, and S only

C
P, R, and S only

D
Q, R, and S only

Solution

Blood and lymph both are fluid tissue that helps in transportation and immunity respectively. Blood consists of plasma and cells such as WBC, RBC, platelets, and plasma proteins. On the other hand, lymph contains salt, water, fat, and WBC. Lymphocytes are a type of white blood cells. Thus, the correct answer is option D.
Question 8
1 / -0

Mature cork cells are

A
Dead

B
Living

C
Transparent

D
None of these
Solution
- Cork is a non-living (dead), water-resistant and protective tissue. It is present at the periphery of the bark. During the secondary growth phase, when the plant starts increasing stem diameter , cork displaces the epidermis layer of the stem.
Hence, option A is correct.
Question 9
1 / -0

Which is the correct combination about the figure?

A
(a) Dendrite, (b) Cell body, (c) Dendron, (d) Synaptic knob

B
(a) Dendrite, (b) Cell body, (c) Axon, (d) Synaptic knob

C
(a) Synaps, (b) Cell body, (c) Axon, (d) Synaptic knob

D
(a) Dendrite, (b) Myelin sheath, (c) Axon, (d) Synaptic knob
Solution
- Dendrites receive impulses. It is represented by (a).
- The cell body or cyton contains the nucleus and cell organelles. It is represented by (b).
- Axon (It is represented by (c)) is an elongated dendron that transfers the impulse to another nerve through a knob-like structure which is known as a synaptic knob that contains neurotransmitters (chemical transmission of signal). It is represented by (d).
So, the correct answer is option B.
Question 10
1 / -0

A rare plant in a botanical garden has been infected with specific fungi that feed on sugar molecules. After careful examination, a botanists suggested the following surgical intervention to get rid of the fungi and prevent its spread to apical portions: removing the infected portion so that a ring of bark about 2 inches in height and about 1-2 cms wide is removed. This will remove the cambial cells, phloem, endodermis, cortex and epidermis of the stem. Which of the following will be a consequence of such a surgical intervention?

A
Flow of food will be affected but flow of water upwards will be maintained.

B
Flow of water upward will be lost but flow of food will be maintained.

C
Both flow of food and water upward will be lost

D
Neither the flow of food nor water movement will be affected.
