What else can I help you with?
Is a single cell alive?
Yes, a single cell is considered alive because it exhibits the characteristics of life, such as metabolism, growth, response to stimuli, and reproduction.
How do all multicellular organisms begin?
Multicellular organisms begin as a single fertilized cell called a zygote. The zygote undergoes repeated rounds of cell division and specialization to form different cell types, ultimately developing into a multicellular organism. This process is known as embryogenesis.
Do all living organisms begin life as a single cell?
Well, that depends how strictly you want to define your terms. This is because some organisms reproduce by cell division, but not grow (as in physical, individual, singular growth). But if instead of grow you mean proliferate (meaning to become more of whether it be growth or reproduction) then we must define cell division. Since some organisms proliferate by cell budding (not strictly cell division) they would not fall under this category. Therefore if you meant do all living organisms proliferate by multiplying cells, then yes, in laymans terms. However if you meant strictly any of the above, then no.
Can a single living cell not be a living organism?
All living things are organisms. There is no such thing as a living cell that is not an organism.
Describes an organism that consists of a single cell?
An example of an organism that consists of a single cell is a bacterium. Bacteria are unicellular organisms that can carry out all the processes of life within a single cell, including metabolism, reproduction, and response to environmental stimuli.
What do all organisms begin life as a?
As a single cell.
How did every single person begin life?
When an egg was fertilized by a sperm cell.
Does an elephant begin it's life 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.
How do multicellular organisms begin?
multicellular organisms begin as a single cell.
Do all 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.
Did you begin as a single cell?
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.
How does the human life begin?
With a sperm cell and a egg cell.
What cell does every human being begin life as?
Every human being begins life as a single cell known as a zygote, formed through the union of an egg cell and a sperm cell during fertilization.
How did life exist?
from a single cell microorganisim.
How life existed?
from a single cell microorganisim.
When does life begin after birth or during union of the egg cell and sperm cell?
Life begins when the egg cell and sperm cell unite to form the zygote.
Is it true that a single cell has all of the items necessary to carry out life's activities?
depends on what kind of single cell you are talking about. if it a single cell in bacteria, then yes, it does, but a single cell in the human body, I'm not so sure of that
