Is there any organism that has only one cell ? If any, what is that ? and how can it lead its life ? Does it need to develop whereas it is undividable ?
Thanks

My question is too easy right ?Monique said:The are more kinds of unicellular organism on this world than there are kinds of multicellular organisms.. bacteria, protozoa, unicellular algae, unicellular fungi or yeasts are the main groups..
A cell is the basic unit of life that makes up all living organisms. It is the smallest structure that can perform all the necessary functions of life, such as obtaining nutrients, converting energy, and replicating.
There are two main types of cells: prokaryotic and eukaryotic. Prokaryotic cells, such as bacteria, do not have a defined nucleus, while eukaryotic cells, such as animal and plant cells, have a distinct nucleus and membrane-bound organelles.
Cells have many functions, including obtaining and converting energy, synthesizing proteins and other molecules, and replicating. They also have specialized functions, such as nerve cells transmitting signals and muscle cells contracting.
Cells communicate through various methods, including chemical signaling and direct contact. Hormones, neurotransmitters, and growth factors are examples of chemical signals that allow cells to communicate and coordinate their activities.
Cells can reproduce through two methods: mitosis and meiosis. Mitosis is the process by which a cell divides into two identical daughter cells, while meiosis is a specialized form of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell.
