Refer the given figures and select the correct option.

Biology Question Image

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 3

The figure represents asexual type of reproduction Offsprings resulting from this type of reproduction are genetically identical to parent, so they can be called clones. Development of an egg (ovum) into a complete individual without fertilization is known as parthenogenesis. It is observed in many invertebrates (rotifers, arthropods), insects bees, wasps) and some birds, etc.

Test: Asexual Reproduction (Old NCERT) - Question 4

Read the following statements about asexual reproduction and select the correct ones.
(i) It involves a single parent.
(ii) It is slower than sexual reproduction.
(iii) It produces progeny that are genetically identical with the parent but not with one another.
(iv) The progeny of asexual reproduction can be termed as clones.

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 4

When offspring are produced by a single parent with or without the involvement of gamete formation, the reproduction is called asexual. As a result, the offspring that are produced are not only similar to one another but are also the exact copies of their parent. Such a group of morphologically and genetically similar individuals is called clone. Asexual reproduction occurs usually in unicellular organisms, such as monerans, protists, plants and certain animals. It is faster than sexual reproduction.

Read the following statements about 'Terror of Bengal' and select the correct ones.
(i) Terror of Bengal' is the name given to water hyacinth (Eichhornia), an algae.
(ii) Eichhornia was introduced in India due to its aesthetic value.
(iii)  Eichhornia drains oxygen from the water which leads to death of fishes.

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 9

Water hyacinth or "Terror of Bengal" is an aquatic plant which is one of the most invading weeds found growing in the standing water. It is also called as "blue devil" as it takes oxygen from the water which causes death of fishes. This plant was introduced in India for its beautiful flowers and shape of leaves. It can propagate vegetatively at a fast rate and spread all over the water body in a short time. It is very difficult to remove it from the water body.

Test: Asexual Reproduction (Old NCERT) - Question 10

Refer the given figures which show three different types of fission. Select the option which correctly matches them with the organism in which they occur.

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 10

Figure (i) shows longitudinal binary fission in Euglena, (ii) shows transverse binary fission in Paramecium and (iii) shows multiple fission in uncysted Amoeba.

Test: Asexual Reproduction (Old NCERT) - Question 11

Read the following statements and select the correct option.
Statement 1: Many plants are propagated vegetatively even though they bear seeds.
Statement 2: Sweet potatoes multiply vegetatively by root tubers.

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 11

Vegetative propagation is the formation of new plants from vegetative units such as buds, tubers, rhizomes, etc. This method produces a large number of population of clones in short time. It preserves purity, resistance and good qualities of race/variety indefinitely. Fleshy roots (root tubers) which develop adventitious buds also take part in vegetative propagation.
Example: Sweet potato.

Test: Asexual Reproduction (Old NCERT) - Question 12

It is a common method of vegetative propagation in which 20 - 30 cm long pieces of one year old stems are cut, their lower ends are dipped in root promoting hormones and are then planted in the soil, which then develop adventitious roots. This method of vegetative propagation is performed in

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 12

The method of vegetative propagation described in the question is performed in Begonia and Bryophyllum plants.

Begonia and Bryophyllum plants can be propagated by stem cuttings, where 20-30 cm long pieces of one-year-old stems are cut and their lower ends are treated with root-promoting hormones such as auxins. These stem cuttings are then planted in soil, and after some time they develop adventitious roots, which grow from the base of the stem. The newly formed roots allow the stem cutting to grow into a new plant.

Lemon, orange, rose, and sugarcane can also be propagated through vegetative methods such as stem cuttings, but the specific method described in the question is not commonly used for these plants.

Test: Asexual Reproduction (Old NCERT) - Question 13

Vegetative propagation is the term used for

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 13

Vegetative propagation (vegetative reproduction) is the formation of new plants from vegetative units such as buds, tubers, rhizomes, etc. This term is used for asexual reproduction in plants. Plants with reduced power of sexual reproduction, long dormant period of seed or poor viability are multiplied easily through vegetative propagation.

Test: Asexual Reproduction (Old NCERT) - Question 14

'Clones' are individuals that have exactly the same

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 14

Clone is population of genetically identical organisms or cells derived from a orignal single organismor cell by asexual reproduction.

Test: Asexual Reproduction (Old NCERT) - Question 15

Which of the following options correctly identities artificial and natural methods of vegetative propagation?

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 15

Layering is a type of horticultural or artificial method of vegetative propagation in which adventitious roots are induced to develop on a soft stem while it is still attached to the plant. Bulbils are multicellular fleshy buds that take part in natural vegetative propagation.
Example: Oxalis, Agave, pineapple.

Test: Asexual Reproduction (Old NCERT) - Question 16

Which of the following cannot serve as a vegetative propagule?

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 16

New buds arise from node, not from internode, hence a middle piece of sugarcane (internode) cannot serve as a vegetative propagule.

Test: Asexual Reproduction (Old NCERT) - Question 17

Select the mismatched pair of organism and their mode multiplication.

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 17

Zoospores are formed during favourable conditions with proper growth of the plant. Any cell except holdfast is capable of producing zoospores. The protoplast either develops into a single zoospore or undergoes division and forms 2, 4, 8, 16 or 32 units. Each unit contains a single nucleus and cytoplasm. These small units form zoospores.
The Chlamydomonas during sexual reproduction involves three stages. They are the;
- Gametogenesis:The process of gametogenesis occurs by repeated division of the protoplast giving rise to 16- 32 gametes from a single cell.
- Syngamy: It is the process of fusion of gametes as a result in the formation of zygote. These zygotes formed will then transform into zygospores.
- Zygospore formation: Zygospore are the spores which have thick walls to protect from the extreme environment. Under favourable conditions the zygospore germinates.

Test: Asexual Reproduction (Old NCERT) - Question 18

Which of the following is not used for vegetative propagation?

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 18

In sexually reproducing organisms, the male gamele is called the antherozoid or sperm and the known as the egg or ovum. They are not used for vegitative propagation.

Test: Asexual Reproduction (Old NCERT) - Question 19

Which of the following options shows two plants in which new plantlets arise from the same organ?

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 19

New plantlets in potato and sugarcane arise from bud on stem. Tubers have buds over their nodes or eyes. The buds produce new plantlets when a stem tuber or a part of it having a node is placed in the soil. Sugarcane is propagated by planting segments of stems having atleast one node.

Test: Asexual Reproduction (Old NCERT) - Question 20

Which one of the following processes results in the formation of a clone of bacteria?

Detailed Solution for Test: Asexual Reproduction (Old NCERT) - Question 20

In binary fission, the parent organism divides into two halves, each half forming an independent daughters organism. Binary fission involves mitosis. The resultant  offspring are genetically identical to the parent and to each other.
