Sexual Reproduction in Flowering Plants Quiz NEET

Click to START

#1. Pollen grains can be stored for several years in liquid nitrogen having a temperature of

–120°C

–80°C

–160°C

–196°C

Pollen grains are stored using cryopreservation at -196°C in liquid nitrogen. This helps in long-term storage and conservation

#2. Which of the following has proved helpful in preserving pollen as fossils?

Pollenkitt

Cellulosic intine

Sporopollenin

Oil content

Sporopollenin cannot be degraded by enzyme; strong acids and alkali, therefore it is helpful in preserving pollen as fossil.

#3. A dioecious flowering plant prevents both

Autogamy and xenogamy

Autogamy and geitonogamy

Geitonogamy and xenogamy

Cleistogamy and xenogamy

When unisexual male and female flowers are present on different plants the condition is called dioecious and it prevents both autogamy and geitonogamy.

#4. Functional megaspore in an angiosperm develops into

Ovule

Endosperm

Embryo sac

Embryo

#5. Flowers which have single ovule in the ovary and are packed into inflorescence are usually pollinated by

Water

Bee

Wind

Bat

Wind pollination or anemophily is favoured by flowers having a single ovule in each ovary, and numerous flowers packed in an inflorescence. Wind pollination is a non-directional pollination.

#6. Double fertilization is exhibited by

Gymnosperms

Algae

Fungi

Angiosperms

Double fertilization is a characteristic feature exhibited by angiosperms. It involves syngamy and triple fusion.

#7. In majority of angiosperms

Egg has a filiform apparatus

There are numerous antipodal cells

Reduction division occurs in the megaspore mother cells

A small central cell is present in the embryo sac

Megaspore Mother Cell (MMC) undergoes meiosis to form megaspore.

#8. Pollination in water hyacinth and water lily is brought about by the agency of

Water

Insects or wind

Birds

Bats

Water hyacinth and water lily are aquatic plants pollinated by insect or wind.

#9. The ovule of an angiosperm is technically equivalent to

Megasporangium

Megasporophyll

Megaspore mother cell

Megaspore

Integumented and stalked megasporangium is called ovule.

#10. Which one of the following statements is not true?

Stored pollen in liquid nitrogen can be used in the crop breeding programmes

Tapetum helps in the dehiscence of anther

Exine of pollen grains is made up of sporopollenin

Pollen grains of many species cause severe allergies

Tapetum provides nourishment to developing pollen grain.

#11. Proximal end of the filament of stamen is attached to the

Thalamus or petal

Anther

Connective

Placenta

A typical stamen consist of anther and filament. The proximal end of filament is attached to thalamus or petal of the flower where as distal and bears anther.

#12. The coconut water from tender coconut represents

Free nuclear endosperm

Endocarp

Fleshy mesocarp

Free nuclear proembryo

Coconut milk represents free nuclear endosperm where the division of PEN is not followed by cytokinesis.

#13. Which of the following statements is not correct?

Some reptiles have also been reported as pollinators in some plant species

Pollen grains of many species can germinate on the stigma of a flower, but only one pollen tube of the same species grows into the style

Insects that consume pollen or nectar without bringing about pollination are called pollen/nectar robbers

Pollen germination and pollen tube growth are regulated by chemical components of pollen interacting with those of the pistil

Pollen grains of different species are incompatible, so they fail to germinate.

#14. Seed formation without fertilization in flowering plants involves the process of

Apomixis

Sporulation

Budding

Somatic hybridization

Apomixis is a special mechanism to produce seeds without fertilisation.

#15. Male gametophyte in angiosperms produces

Three sperms

Two sperms and a vegetative cell

Single sperm and a vegetative cell

Single sperm and two vegetative cells

In angiosperms, pollen grain is first male gametophyte. Pollen grain divides into generative cell and vegetative cell. Generative cell further divides into two sperms.

#16. Filiform apparatus is characteristic feature of :

Synergids

Generative cell

Nucellar embryo

Aleurone cell

Filiform apparatus is finger like projections in each synergid.

#17. The wheat grain has an embryo with one large shield-shaped cotyledon known as:

Coleoptile

Epiblast

Coleorrhiza

Scutellum

Scutellum is the large persistent cotyledon in embryo of wheat grain.

#18. Which one of the following fruits is parthenocarpic?

Banana

Brinjal

Apple

Jackfruit

Formation of fruit without fertilisation is called parthenocarpy. Banana is a parthenocarpic fruit therefore seedless.

#19. In angiosperms, microsporogenesis and megasporogenesis

Occur in ovule

Occur in anther

Form gametes without further divisions

Involve meiosis

In angiosperms, microsporogenesis and megasporogenesis involve meiosis.

#20. Which one of the following statements is not true?

Honey is made by bees by digesting pollen collected from flowers

Pollen grains are rich in nutrients, and they are used in the form of tablets and syrups

Pollen grains of some plants cause severe allergies and bronchial afflictions in some people

The flowers pollinated by flies and bats secrete foul odour to attract them

Honey is made by using nectar of flowering plants.

#21. The hilum is a scar on the

Seed, where micropyle was present

Seed, where funicle was attached

Fruit, where it was attached to pedicel

Fruit, where style was present

The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit.

#22. Which one of the following may require pollinators, but is genetically similar to autogamy?

Cleistogamy

Geitonogamy

Xenogamy

Apogamy

Geitonogamy is genetically similar to autogamy since the pollen grains comes from the same plant.

#23. Which of the following are the important floral rewards to the animal pollinators?

Protein pellicle and stigmatic exudates

Colour and large size of flower

Nectar and pollen grains

Floral fragrance and calcium crystals

Nectar and pollen grains are the usual floral rewards.

#24. Transmission tissue is characteristic feature of

Wet stigma

Hollow style

Solid style

Dry stigma

A solid style has transmission tissue with large intercellular spaces which allows growth of pollen tube.

#25. Geitonogamy involves

Fertilization of a flower by the pollen from another flower of the same plant

Fertilization of a flower by the pollen from the same flower

Fertilization of a flower by the pollen from a flower of another plant in the same population

Fertilization of a flower by the pollen from a flower of another plant belonging to a distant population

Geitonogamy is transfer of pollen grains from the anther to the stigma of another flower of the same plant.

#26. Pollen tablets are available in the market for

In vitro fertilization

Breeding Equisetum

Supplementing food

Ex situ conservation

Pollen grains are rich in nutrients and it has become a fashion in recent years to use pollen tablets as food supplements.

#27. Function of filiform apparatus is to

Recognize the suitable pollen at stigma

Stimulate division of generative cell

Produce nectar

Guide the entry of pollen tube

Filiform apparatus, present in synergids, play an important role in guiding the pollen tube into the synergid.

#28. Perisperm differs from endosperm in

Having no reserve food

Being a diploid tissue

Its formation by fusion of secondary nucleus with several sperms

Being a haploid tissue

Nucellus remnant is called – Perisperm (2n)

#29. Double fertilization is

Fusion of two male gametes of a pollen tube with two different eggs

Fusion of one male gamete with two polar nuclei

Syngamy and triple fusion

Fusion of two male gametes with one egg

Double fertilization is a unique phenomenon that occur in angiosperms only.
Syngamy Triple fusion = Double fertilization

Finish
