GENERAL HISTOLOGY

Detailed explanation-1: -Cells are the smallest units (or most basic building blocks) of life, and all cells come from preexisting cells through the process of cell division. Life cannot be created in a laboratory.

Detailed explanation-2: -No matter what the cell, all cells come from preexisting cells through the process of cell division. The cell may be the simplest bacterium or a complex muscle, bone, or blood cell. The cell may comprise the whole organism, or be just one cell of trillions.

Detailed explanation-3: -Yes, all living cells arise from pre-existing cells through division. Prokaryotic cells produce genetically identical daughter cells through binary fission. In an eukaryotic organism, namely an animal, a new zygote is produced through fertilization of a haploid egg by a haploid sperm.

Detailed explanation-4: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Detailed explanation-5: -The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
