A cell is the structural and basic unit of life. The study of cells from their basic structure to the functions of each cell organelle is called cell biology. Robert Hooke was the first biologist who discovered cells.
All organisms are made up of cells. They can consist of one cell (unicellular) or many cells (multicellular). Mycoplasmas are the smallest known cells. Cells are the building blocks of all living things. They give structure to the body and transform nutrients from food into energy.
Cells are complex and their components perform different functions in the body. They come in different shapes and sizes, like the bricks of buildings. Our body is made up of cells of different shapes and sizes.

Explanation:
Cartilage is the connective tissue consisting of large round densely packed cells with the nucleus pushed to the side. Other forms of connective tissue include Dense regular and irregular connective tissues, fibrous connective tissues, and loose or areolar connective tissue.
The connective tissue consisting of large round densely packed cells with the nucleus pushed to the side is called cartilage. Cartilage is a type of connective tissue that has a large amount of ground substance matrix and cells called chondrocytes, along with some amount of fibers. Other forms of connective tissue include Dense regular and irregular connective tissues, fibrous connective tissues, loose or areolar connective tissue. Dense connective tissue, including regular and irregular, consists of collagenous fibers packed in different alignments. Fibrous connective tissues contain copious amounts of collagen fibers but few cells or matrix material. Finally, loose or areolar connective tissue is encapsulated in a matrix and is found around blood vessels and most body organs.

yellow insects population will decline
Explanation:
In a lush green area , it is easy for green insects to hide themselves. Thus, yellow colored insects can be easily traced by the predator species. This will cause decrease in population of yellow insects with time, while the green insect population will keep on growing. Removal of yellow insects also makes more food available for green insects . Hence without any environmental restriction , the green insects population will flourish well.
