Yes. Everyone begins as a single cell. A single-celled egg, fertilized by a single-cell sperm. Which then becomes a zygote, then a blastula, then slowly a fetus.
multicellular organisms begin as a single cell.
Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
As a single cell.
When an egg was fertilized by a sperm cell.
All life begins as a single cell.
Yes. All organisms that are produced by sexual reproduction start out as a single cell called a zygote. The zygote is the cell that results from the fertilization of the egg by the sperm.
All complex organisms begin as a single cell. As they divide into 2, 4, 8, 16 cells , they begin to become certain tissues. Further divisions produce organs, organ systems and then the entire organism. The study of embryology will help you to understand this process.
By cellular reproduction. Cells reproduce asexually so if there is only one cell and it reproduces then there will be two cells and thus multicellular.
a single cell is more differentiated
Single Celled
The blood cell begin their lives in the bone marrow from a single type of cell called pluripotent hematopoietic stem cell.All the circulating blood cells are eventually derived from PHSC.
Bacteria are single-celled organisms
