Propolis is a red or brown resinous substance collected by honeybees from tree buds, used by them to fill crevices and to fix and varnish honey combs.

The worker bees are sterile females and cannot reproduce. They perform all function for the hives and thus, called as worker honey bee. They have the responsibility of maturing honey, feeding the larvae and drones, grooming the queen, cleaning cells, producing wax, pollinating flowers and much more.

Honey is a sweet food made by honeybees using nectar from flowers. The other main product of honey bees is beeswax.

The term pasturage refers to plants and vegetation on which grazing animals feed. Paturage is the flora from which honey bees collect nectar, pollen, and bee glue . These decide the quality and quantity of honey produced by honey bees.

Explant is any portion taken from a plant that will be used to initiate a culture. It can be a portion of the shoot or of the leaves or even just some cells.

Sunflower oil is produced from the seeds of sunflower. Sunflower seeds are rich in protein and yield a high quality vegetable oil used as cooking oil.

Sheep is an animal that has a rich layer of wool over it. It is used for economic purposes. Many blankets, sweaters, jackets, etc are obtained from sheep wool.

Isinglass is the transparent form of gelatin used to form jellies, glue and in the refining of beer, wine etc. It is prepared from dried swim blabber of fish, especially sturgeon fish.

Plant breeding is the genetic improvement of the crop in order to create desired plant types that are better suited for cultivation, gives better yields and are disease resistant.

Cuniculture is the practice of breeding and raising domestic rabbits as livestock for their meat, fur and wool.

Fungicides and antibiotics are chemicals that kill pathogenic fungi and bacteria, respectively.

Protoplast is a plant cell without a cell wall.

A collection of all the alleles of all the genes of a crop plant is called germplasm collection.

Oxytocin helps in lactation in cattle. The breeds of cattle that are reared for milk production on a commercial scale are injected with the hormone oxytocin to secrete more milk. This hormone causes contraction of the mammary glands and also allows ejection of milk.

A group of animals which are related by descent and share many similarities are referred to as breed.

These are needed to dissolve the cell wall.

Thick stem, long internodes, high sugar content and disease resistant, combination would a sugarcane farmer look for in the sugarcane crop.

The queen after fertilization lays fertilized and unfertilized eggs both. From unfertilized eggs male bees emerge which are known as drones.

Plants can be disease resistant by breeding with a plant which naturally have resistance gene. Generally, wild varieties of plants have resistance gene for disease so breed important crop with their wild varieties to get disease resistant plants.

Carnauba wax is made from the leaves of the palm tree. It is also known as palm wax. It is obtained from the leaves of the carnauba palm by collecting and drying them, beating them to loosen the wax, then refining and bleaching the wax.

Explant is used for growing a whole new plant.

Black rot of crucifers is a bacterial disease.

Sonalika and Kalyan Sona are varieties of wheat.

Nerve cells cannot replicate under Tissue culture conditions hence they cannot be grown by the tissue culture technique.

Enough infrastructures is available for the purpose and there is not dearth of trained manpower because of over thousands of years of experience in farming.

Poultry farming is undertaken to raise domestic fowl for egg production and chicken meat.
Chickens that are reared especially for meat are called broilers.
Broilers have tender meat with soft, pliable, smooth textured skin and flexible breast bone cartilage.

Rohu is the most demanded fish because it is easily aquacultured so it is cheaper.

The practice of beekeeping is called as apiculture. It is done to get honey and beeswax.

Because of faster rate of multiplication; meristematic cells are not affected by virus.

Wax is a product of apiculture used in cosmetics and polishes.

When chicken is properly cooked, it helps in destroying the virus of bird flu.

Interspecific breeding occurs between genetically dissimilar parents of different species. A mule is the offspring of a male donkey and a female horse. The organism is sterile in nature and not capable of exchanging the genes or interbreeding with each other.

Increased homozygosity is helpful in obtaining a pure line of breed.

Lysine and tryptophan are essential amino acids.
