Biology of Insects and Pollination Questions

Multiple choice zoology production of food from animals animal breeding animal husbandry and its importance introduction to animal husbandry

What is the name given to the domestication of bees?

  1. Sericulture

  2. Apiculture

  3. Tissue culture

  4. Pisciculture
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The raising and care of bees for commercial or agricultural purposes is known as apiculture. It is the maintenance of honeybee colonies, commonly in hives, by humans. A beekeeper keeps bees in order to collect honey and other products of the hive (including beeswax, propolis, pollen and royal jelly) to pollinate crops. A location where bees are kept is called as an apiary or bee yard. Hence, option B is correct.

Rearing of bees is

  1. Sericulture

  2. Apiculture

  3. Silviculture

  4. Horticulture
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rearing of bees is called as apiculture. It is called as beekeeping. It deals with the commercial production of honey by maintaining man-made honey bee colonies. Sericulture is also called as silk farming. In this, silkworms is cultivated to produce silk. Silviculture deals with the cultivation of trees. Horticulture deals with the garden cultivation and management. So, the correct answer is 'Apiculture'.

Multiple choice zoology plant reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

Haplodiploidy is found in

  1. Grasshoppers and cockroaches

  2. Birds and reptiles

  3. Butterflies and moths

  4. Honeybees, ants and wasps
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Haploid-diploid mechanism or Haplodiploidy is a unique phenomenon in which an unfertilized egg develops into a male and a fertilized egg develops into a female. Therefore, the female is diploid (2n), and the male is haploid (n). Eggs are formed by meiosis and sperms by mitosis. Fertilization restores the diploid number of  chromosomes in the zygote which gives rise to the female, If the egg is not fertilized, it will still develop but into a male (arrhenotoky or arrhenotokous parthenogenesis). It is seen in hymenopterous insects, such as bees, wasps, saw flies and ants. So, the correct answer is 'Honeybees, ants and wasps'.

Multiple choice zoology biotechnology and its applications transgenic animals transgenic organisms applications of biotechnology

Read the following statements : 
I) Mule is developed by interspecific hybridisation
II) Groups of bees is called 'swarms'
III) For the herd-improvement cross-breeding is employed
IV) In MOET, fertilised egg at 6-8 celled stage is recovered non - surgically

  1. I, II, III, IV are true

  2. III , IV, V are false

  3. I, II, IV are true

  4. I, II, III and V are true
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • As a mule is produced by crossing a female horse with a male donkey, it can be said to be an interspecific hybrid.
  • Swarming can be defined as the process by which a queen bee forms a new colony. Consequently, the term ‘swarms’ is used to refer to the colonies of honey bees.
  • Cross-breeding enables the production of hybrids that are superior in one respect or the other to their respective parents.
  • In MOET, the female is made to produce more eggs than normal, usually 6-8. After the fertilization of these eggs with sperms, these fertilized eggs are non-surgically removed and transferred to other females.
Hence, the correct answer is 'I, II, III, IV are true'.

Multiple choice botany pollination, fertilization and development of endosperm and embryo types of pollination cross pollination pollination and its types

Name the types of pollination which ensures genetic variation?

  1. Parthenocarpy

  2. Cross pollination

  3. Tissue culture

  4. Insects
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • Transfer of pollen grains from the male reproductive organ (anther) of one plant to the female reproductive organ (stigma) of another plant. 
  • Insects and wind are the main agents of cross-pollination.
  • Thus, it creates genetic variations in the plants making it more resistant to diseases and other conditions than the parent plants.

The correct answer is OPTION B.

Multiple choice botany pollination, fertilization and development of endosperm and embryo types of pollination cross pollination pollination and its types

Cross pollination is considered as a/an

  1. Natural method

  2. Artificial method

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cross pollination occur when pollen grains are transferred to a flower from a different plant. The plants that undergo cross pollination often have taller stamens than their carpels. They use mechanisms to ensure that the pollen grains are spread to other plants' flowers. The process of cross pollination requires the help of abiotic or biotic agents like wind, water, insects, birds, bats, snails and other animals as pollinators.

Myrmecophily is an association between higher plant and.

  1. Bacteria

  2. Fungi

  3. Blue-green algae

  4. Ants

D Correct answer
Explanation

Myrmecophily refers to the symbiotic association between ants and other organisms, including plants, where the plants provide shelter or food in exchange for protection.

Some plants have a habit of harbouring ants to save the plants from damage by other animals which is known as

  1. Entomophily

  2. Myrmacrophily

  3. Anemophily

  4. Hydrophily

  5. Zoophily
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Myrmecophily is the term applied to positive interspecies associations between ants and a variety of other organisms such as plants, other arthropods, and fungi. Myrmecophily refers to mutualistic associations with ants, though in its more general use the term may also refer to commensal or even parasitic interactions. The term myrmecophile is used mainly for animals that associate with ants.

Multiple choice botany male & female gametophytes: structure and development pollen grain androecium male gametophyte

Chemically pollen kitt is made up of lipids and carotenoids.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pollen kitt is a sticky covering found on the surface of pollen grains. It is common in plants that are pollinated by insects. It is composed of lipids and carotenoids and is formed by tapetum. Pollen kitt helps in pollination. Hence, chemically pollen kitt is made up of lipids and carotenoids.

So, the correct answer is 'Lipids and carotenoids'.

Multiple choice botany male & female gametophytes: structure and development pollen grain androecium male gametophyte

The pro-ubisch bodies are converted to ubisch bodies when they become 

coated by ..............

  1. Sporoderm

  2. Sporopollenin

  3. Cutin

  4. Suberin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ubisch bodies have been largely observed in plants, after they were first recorded around the aggregates of mimosoid pollen by Rosanoff. The tapetum may be secretory (glandular) or amoeboid (periplasmodial). The cells of tapetum form pro-ubisch bodies which get surrounded by sporopollenin and now called ubisch bodies. They participate in the formation of pollen exine.
