Weekly Quiz Competition

Question 1
1 / -0

In which part of the human penis are the proteolytic enzymes are located?

A
Foreskin

B
Head

C
Acrosome

D
Corona

Solution

The acrosome is the part of the sperm containing proteolytic enzymes to digest the zona pellucida. It is exposed by the process of capacitation. Then, under the influence of substances released by corona radiata cells, it releases its proteolytic enzymes and penetrates the oocyte.
Question 2
1 / -0

In a female, the nerve endings for sensing sexual pleasure are located in which of the following?

A
Fallopian tubes

B
Mons pubis

C
Clitoris

D
Labia majora

Solution

On the superior end of the labia minora is a small mass of erectile tissue known as the clitoris that contains many nerve endings for sensing sexual pleasure.
Question 3
1 / -0

A fruit is a mature ovary of a flowering plant that is edible and usually eaten raw. Which is the following statements does NOT characterise the fruit development in angiosperms?

A
Each microsporangium contains diploid microspore mother cells.

B
Within the megagametophyte both the two sperm unites with the egg, forming a zygote.

C
After pollination, a tube grows from the pollen through the stigma into the ovary.

D
The zygote gives rise to the endosperm.

Solution

Within the megagametophyte one of the two sperm unites with the egg, forming a zygote, and the second sperm enters the central cell forming the endosperm mother cell, which completes the double fertilisation process.
Question 4
1 / -0

Pollen is a powder made of pollen grains, which produces sperm cells of seed plants. Which of the following statements regarding the pollen production in angiosperms is INCORRECT?

A
Pollen of angiosperms must be transported to the stigma of a compatible flower.

B
The pollen is eventually released when the anther forms openings.

C
Each microspore divides mitotically to form an immature microgametophyte.

D
Each microsporangium contains haploid pollen mother cells.

Solution

Each microsporangium is lined with a nutritive tissue layer called the tapetum and initially contains diploid pollen mother cells.
Question 5
1 / -0

Which of the following regarding the main adaptations of nonvascular plants is INCORRECT?

A
They reproduce both asexually and sexually.

B
The rate of evaporation is slow.

C
The sporophyte grows as a parasite on the gametophyte.

D
The non-vascular plant usually grows in dry places.

Solution

The non-vascular plant usually grows in the moist and shady places. The moist environment is essential for easy uptake of the water, since they lack the vascular tissues like the xylem and the phloem.
Question 6
1 / -0

During the early development of a vascular plant, i.e., before starting the process of photosynthesis the essential nutrients are provided by ____________.

A
locules

B
Strobilus

C
Calyptra

D
Cotyledons

Solution

Two large green hemispherical structures which enclose the embryonic axis is called as the cotyledons. The cotyledons may be one or two in number depending on the type of plant. The cotyledons are important because it give nutrients during the early development of the plant before starting the process of photosynthesis.
Question 7
1 / -0

Bamboos are not trees and their stems do not get thicker with age, and if left unchecked they will form whole forests of plants. They generally propagate through which of the following?

A
Crown

B
Offshoots

C
Rhizomes

D
Tubers

Solution

Offshoots applies to lateral branches on stems of monocots. Date palm, pineapple, banana, and orchids produce offshoots. Bamboo also propagate from offshoots, if left unchecked they will form whole forests of plants.
Question 8
1 / -0

Which of the following male accessory glands is responsible for enhancing the movement of spermatozoa in all the mammals?

A
Prostate Gland

B
Ampullary Glands

C
Vesicular Glands

D
Bulbourethral Glands

Solution

The secretion of this gland is more serous in dogs and more mucous in bulls. It serves to promote the movement of spermatozoa in all the mammals and to form a vaginal plug.
Question 9
1 / -0

Vegetative propagation is usually considered as a cloning method. Strawberries are typically propagated asexually by __________.

A
the runners

B
offset

C
stolon

D
sucker

Solution

Runners are horizontally oriented stems that grow along the soil surface. Their function is vegetative production. For example: number of grasses have stolons. Strawberries are normally propagated asexually by two different methods: runners (stolons) and crown division.
Question 10
1 / -0

Which of the following cells of epididymis are regarded as the undifferentiated precursors of principal cells in human males?

A
Main cells

B
Basal cells

C
Apical cells

D
Stereocilia

Solution

Basal cells are the shorter, pyramid-shaped cells which contact the basal lamina but taper off before their apical surfaces reach the lumen.These are thought to be undifferentiated precursors of principal cells.
