We know that, there are four types of tissue in human body. They are 

1.Muscular
2.Connective
3.Epithelial
4.Nervous

Among these Connective Tissue are most abundant in our body. 

CONNECTIVE TISSUE

Connective tissue is found in between other tissues everywhere in the body, including the nervous system. It develops from the mesoderm.

Functions:

1) Wraps around and cushions and protects organs
2) Stores nutrients
3) Internal support for organs
4) As tendon and ligaments protects joints and attached muscles to bone and each other
5) Runs through organ capsules and in deep layers of skin giving strength

The 3 Elements of Connective Tissue are

1) Ground substance – gel around cells and fibers
2) Fibers – provide strength, elasticity and support
3) Cells

Breeding and management of bees is called Apiculture.

A beekeeper or apiarist keeps bees in order to collect their honey and other products that the hive produces (including beeswax, propolis, flower pollen, bee pollen, and royal jelly), to pollinate crops, or to produce bees for sale to other beekeepers.

A location where bees are kept is called an 'apiary' or 'bee yard.'
