#1. Offsets are produced by

Meiotic divisions

Mitotic divisions

Parthenogenesis

Parthenocarpy

Offset is a vegetative part of a plant, formed by mitosis.
– Meiotic divisions do not occur in somatic cells.
– Parthenogenesis is the formation of embryo from ovum or egg without fertilisation.
– Parthenocarpy is the fruit formed without fertilisation, (generally seedless)

#2. Which of the following flowers only once in its life-time?

Bamboo species

Jackfruit

Papaya

Mango

Bamboo species are monocarpic i.e., flower generally only once in its life-time after 50-100 years.

Jackfruit, papaya and mango are polycarpic i.e., produce flowers and fruits many times in their life-time.

#3. Which one of the following statements is not correct?

Offspring produced by the asexual reproduction are called clone

Microscopic, motile asexual reproductive structures are called zoospores

In potato, banana and ginger, the plantlets arise from the internodes present in the modified stem

Water hyacinth, growing in the standing water, drains oxygen from water that leads to the death of fishes

In potato, banana and ginger, the plantlets arise from the nodes present on modified stem.

#4. Which one of the following generates new genetic combinations leading to variation?

Vegetative reproduction

Parthenogenesis

Sexual reproduction

Nucellar polyembryony

#5. In bryophytes and pteridophytes, transport of male gametes requires:

Water

Wind

Birds

Insects

In several simple plants like algae, bryophytes and pteridophytes, water is the medium through which male gamete transfer takes place.

#6. In ginger vegetative propagation occurs through

Runners

Rhizome

Offsets

Bulbils

#7. Which one of the following is wrong about Chara?

Upper oogonium and lower round antheridium

Globule and nucule present on the same plant

Upper antheridium and lower oogonium

Globule is male reproductive structure

NCERT Class 12th Page No.12 Figure 1.6 (C) [AIPMT-2014]

#8. Isogamous condition with non-flagellated gametes is found in

Spirogyra

Volvox

Fucus

Chlamydomonas

#9. Which one of the following is correctly matched?

Chlamydomonas – Conidia

Yeast – Zoospores

Onion – Bulb

Ginger – Sucker

NCERT Class 12th Page No.6 & 7 ( Figure 1.3 and 1.4 ) Very Important Please Revise

#10. Monoecious plant of Chara shows occurrence of

Stamen and carpel on the same plant

Upper antheridium and lower oogonium on the same plant

Upper oogonium and lower antheridium on the same plant

Antheridiophore and archegoniophore on the same plant

Above we already discussed this topic.

#11. In the process of asexual reproduction

Large number of individuals are produced due to involvement of reduction division

Individuals are genetically similar to one another but not to their parent

There is no need to search for a mate

Gametes may or may not be fused

#12. In vegetative propagule of potato and Bryophyllum new plants arise from respectively

Axillary bud, Adventitious bud

Adventitious bud, Axillary bud

Axillary bud, Axillary bud

Leaf bud, Axillary bud

Axillary bud → Potato

Adventitious bud A → Bryophyllum

#13. Which of the following plants produce non-motile male gametes?

Mangifera, Pinus

Ulothrix, Marchantia

Strobilanthus, Chara

Spirogyra, Ulothrix

Mangifera → Angiosperm

Pinus → Gymnosperm

#14. Arrange the following w.r.t. increasing life span : Rose, Fruit fly, Rice

Fruit fly, Rice, Rose

Rose, Rice, Fruit fly

Rice, Rose, Fruit fly

Fruit fly, Rose, Rice

#15. Most common asexual structure produced in algae is

Thick walled

Multicellular

Flagellated

Produced in chains

Zoosperes possess flagella.

#16. In which of the following plants root bud is involved in vegetative propagation?

Sugarcane

Banana

Ginger

Dahlia

Sugarcane→ Segment of stem with atleast one node

Banana → Rhizome

Ginger → Rhizome

Dhalia → Root buds

#17. Which of the following vegetative propagule represents large size fleshy bud?

Bulbil

Bulb

Sucker

Rhizome

#18. Majority of sexually reproducing organisms form

Isogametes

Homogametes

Heterogametes

More than one option is correct

#19. Arrange the following plants w.r.t. increasing number of chromosome Rice, Maize, Apple

Maize, Rice, Apple

Apple, Rice, Maize

Apple, Maize, Rice

Rice, Maize, Apple

#20. Strobilanthus kunthiana

Shows flowering once in 12 months

Transformed hilly tracks of Kerala, Karnataka, Tamil Nadu into blue stretches

Showed flowering during November-December 2004

An annual plant

#21. Self fertilisation is seen in

Unisexual flower of date palm

Bisexual flower of coconut

Bisexual flower of pea

Unisexual flower of papaya

Bud pollination in pea.
