scientist Robert Hooke
The term “cells” was first coined in 1665 by a British scientist Robert Hooke. He was the first person to study living things under a microscope and examined a thin slice of cork under a microscope and observed honeycomb-like structures. Robert Hooke called these structures as cells.
Who are the 3 scientists who discovered cells?
The ideas of all three scientists — Schwann, Schleiden, and Virchow — led to cell theory, which is one of the fundamental theories unifying all of biology. Cell theory states that: All organisms are made of one or more cells.
Who is the mother of cell?
In cell division, a mother or parent cell is the cell that divides to give rise to two daughter cells. In mitosis, the two daughter cells contain the same genetic content as the mother cell.
What is the smallest cell?
mycoplasmas
As of today, the mycoplasmas are thought to be the smallest living cells in the biological world (Fig. 1). They have a minimal size of approximately 0.2 micrometers, which makes them smaller than some of the poxviruses.

What are the 4 types of cells?

- Connective Tissue Cells.
What is the name of blood cells?
Also called erythrocyte and RBC. Blood cells. Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets.
Are cells alive?
Cells are regarded as alive, because the have the ability to self replicate (produce copies of themselves). The main components of cell replication are DNA, RNA and Ribosome. The DNA encodes the genetic sequence which is like a recipe for making proteins.
How is the first cell formed?

What is the name of cell in Excel?
Select the single cell or range of cells that you want to name. Click Formulas → Defined Names → Define Name (Alt+MZND) to open the New Name dialog box. Naming a cell range in the Excel worksheet in the New Name dialog box. Type the name for the selected cell or cell range in the Name Box.
How cell is formed?
Two cells are formed from one cell through the process of cell division. In cell division, the DNA within a cell is replicated. The two copies of the DNA are then separated into two different cell nuclei. The cell then splits into two pieces, each piece containing its own set of DNA.
