All life begins as a single cell.
Yes. That cell is called the zygote. All sexually reproducing organisms start life as a zygote.

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.
It is likely that the earliest kind of cell resembled a bacterium. That is the simplest type of cell, in terms of general structure, and evolution proceeds from the simple to the complex.
The statement which best compares a multicellular organism to a single-celled organism is their functions. While multicellular organisms use organ systems to perform life functions, single-celled organisms do not use organs for the life functions.
Single-celled organisms.
The root hair single cell is 80 - 1500um long. Its diameter is 5-17um. The root hair cell life is 2-3 weeks.
As a single cell.
When an egg was fertilized by a sperm 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.
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.
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.
A single cell has everything necessary to carry out life's activities.
With a sperm cell and a egg cell.
gotta have single cell life before you can have multi cell life.

Life begins when the egg cell and sperm cell unite to form the zygote.
