Why does cell division take place in single cell organisms?
Cell division takes place in single-celled organisms to reproduce and pass on genetic information.
What does a prokaryotic cell look like?
Prokaryotes are single-celled organisms. Because of this, they take on a more oblong shape, lack a number of membranes, and often have a flagellum that assists in propelling themselves forward. in contrast, a eukaryotic cell is one that's part of a multi-celled organism, and as such takes a rounder shape with membranes around the nucleus.
How does a single celled organism get its nutrients?
Easy!! diffusion.. because single celled organisms have a large surface area to volume ratio meaning that there exchange surface is large enough to allow efficient diffusion fast enough to keep the cells alive (1 cell.. lol ). they also aren't very active they can rely on diffusion alone to take up water and other important solutes.. Diffusion through osmosis occurs in single celled organisms when they have a lower water potential inside the cell than outside so water flows into the cell (down the concentration gradient) via a partially permeable membrane. hope that helped from Kate Gibson 16
What is endocystosis?
The word itself means "the process (-osis) a cell (-cyto-) takes in (endo-)". Some single celled organisms take food in by this method.
What are the physical characteristics of an amoeba?
AmoebaIf it is in ponds it is found moving about around the weeds and stones. Some species are found in the damping soil. Amoeba is a protist, so it is a microscopic in size , measuring 0.25 millimeters. It is a single celled life formIt Is also a single celled organism.

What is the difference between one celled organisms and many celled organisms?
Unicellular-It is represented by a single cellAll the activities of the organism are performed by a single cell.There is no division of labour as the single cell has to perform all activities.It consumes the single cell.The life span of the in individual is short.Multicellular-It consists of a large number of cells.A single cell performs one or a few activities of the organism.Cells are specialized to perform different functions of the body so that there is division of labour.Some cells called germ cells take part in reproduction. Others remain intact.The life span is long.

What do cells have to do with living thing?
Cells are living things in and of themselves. There are single celled organism that science defines as alive as you are. You are made up of billions of cells that all have the same DNA (genetic information that is the key to making everything that you are) as each other. Humans, along with all other multicellular organisms, start as one living cell. This is the entirety of what the organism is at this point. As that cell divides and replicates itself the organism begins to take shape and eventually matures into its fully formed state. Cells continue to die and replicate in this stage. If the science behind DNA and how different genes can be turned on and off were better understood it is theoretically possible to grow an identical body from a single human cell. The first cell of any organism is the organism and is alive. If that cell were not alive or the organism itself the organism could never and would never exist.
Who discovered first single cell organism?
Anton van Leeuwenhoek , a dutch merchant, discovered the single celled organism.He was a microscope seller and he decided to take a look at pond scum. He saw that they were small animals.He named them animalcules which means small animal. Today we call animalcules single celled organisms. His name is Van Leeuwenhoek
What is the difference between prokaryotic cells and an animal cell?
A prokaryote is a single celled organism, animals cells are not organisms. Prokaryotes do not have membrane bound nucleus or organelles. They also don't have DNA that is organized into chromosomes. These are usually bacteria and viruses. They reproduce by invading animal cells. They 'take over' the invaded cell, using the reproductive function of that cell to make more virus or bacteria.
How long did it take for multi celled organismsto develop from the earliest single-celled organisms?
They say about 100 years but there not certain.
