Question 1
1 / -0

New banana plants develop from:

A
Rhizome

B
Sucker

C
Stolon

D
Both A and B
Solution
Bananas are developed from rhizomes. Rhizomes are the main underground stem that store food during unfavourable conditions. These have buds for the formation of new aerial shoots during favourable conditions. Rhizomes undergo vegetative reproduction through these buds.
Sucker is a lateral shoot that develops from the rhizome and develops into a new banana plant.
So, the correct answer is option D.
Question 2
1 / -0

What is wrong about rhizome

A
Rhizome stores food

B
It has nodes and internodes

C
It bears foliage or scale leaves

D
It does not possess buds
Question 3
1 / -0

This is not an example of aerial modification of stem

A
Corm

B
Tendril

C
Thorn

D
Phylloclade
Question 4
1 / -0

Which is correctly matched

A
Onion-Bulb

B
Ginger-Sucker

C
Chlamydomonas-Conidia

D
Yeast-Zoospores
Question 5
1 / -0

Estrous cycle is characteristic of

A
Human females.

B
Mammalian females.

C
Mammalian females other than primates.

D
Mammals.

Solution

A. option - C
B. Explanation for correct option -
Estrous cycle consists of cyclic changes in female reproductive system of non primate mammals .
The females are highly receptive during estrous period. It is an indication of breeding period because one or more periods of estrous may occur during the breeding season of a species.
Hence the correct option is C
Question 6
1 / -0

Which one of the following set of plant reproduces by means of rhizomes, corms, and tuber respectively ?

A
Potato, ginger, zimikand

B
Ginger, potato, zimikand

C
Potato, zimikand, ginger

D
Ginger, zimikand, potato
Solution
Vegetative reproduction is a type of asexual reproduction observed in plants. In this method, the offsprings/ new plants are produced by vegetative parts of the parent plant.
Rhizomes are segmented, fleshy underground stems. They serve as storage and reproductive structures. Eg: Ginger
Corms are swollen underground stems with dry scale leaves covering them. Eg: Zimikand
Tubers are of two types: Stem tubers (swollen parts of stem buried in the soil) and Root tubers (swollen roots used as storage systems). Stem tubers have nodes (appears like eyes) on them. These nodes can produce new shoots. Eg: Potato
Thus, the correct answer is 'Ginger, zimikand, potato'.
Question 7
1 / -0

A rhizome which grows vertically upwards is

A
Corm

B
Stolon

C
Bulbil

D
Rootstock
Question 8
1 / -0

A plant bearing both male and female flowers$$/$$ sex organs is called ________.

A
Monoecious

B
Dioecious

C
Unisexual

D
Bisexual

Solution

The monoecious plants are bisexual because they have both the female or pistillate flowers and the staminate or male flowers. The flowers themselves are unisexual. In such condition, geitonogamous pollination occurs. Corn is an example of the monoecious plant.
Hence, the correct answer is 'Monoecious'
Question 9
1 / -0

Choose the correct option with respect to the following statements.
(i) The genetic constitution of a plant is unaffected by vegetative propagation.
(ii) The rhizome of Ginger serves as an organ of vegetative reproduction.
(iii) Totipotency of cells enables us to micropropagate plants.

A
i and ii correct

B
i, ii, iii all correct

C
Only iii is true

D
Only ii is true

E
ii and iii are true

Solution

Reproduction occurs through vegetative plant structures derived from roots, stems, and leaves. Vegetative structures include rhizomes, runners, bulbs, tubers, corms, and buds.
Because almost all plants are totipotent, plant tissue culture i.e. micropropagation is used for aseptic cells, tissues, organs of their components in invitro.
So the correct option is 'i, ii, iii all correct'.
Question 10
1 / -0

Scaly bulb occurs in

A
Lilium

B
Allium

C
Scilla

D
Ginger
