What is a cell?
The basic and structural component of life is the cell. Cell biology is the study of cells, including their fundamental makeup and each organelle's functions. Cells were initially found by a biologist, Robert Hooke. Cells comprise all living things. They could consist of several cells or just one (unicellular) (multicellular). The tiniest known cells are mycoplasmas. The foundation of all living things are cells. They give the body structure and transform the food's nutrients into energy.
Complex cells have many parts that each serve a different purpose within an organism. Similar to constructing bricks, they come in a variety of sizes and shapes. The cells that make up our body come in a variety of sizes and forms. The smallest unit of organisation in all living things is cells. Cell number varies from organism to organism. When compared to microbes, humans have more cells. Numerous cell organelles that execute specific tasks in order to carry out life processes make up cells. There is a distinct structure for each organelle. The cells also contain the genetic material of the organisms.
Which of the following is made up of a single cell? (a) Tree(b) Lion(c) Bacteria(d) Human
A single cell makes up a bacteria. The cell was found by Robert Hooke in 1665. Under a compound microscope, Robert Hooke examined a piece of bottle cork and detected minute structures that resembled tiny rooms.
