How are single- celled organisms similar and different to multi-celled organisms?
Cells that are part of a multi-cellular organism typically have the same metabolic functions as single-celled organisms, however differences exist. Multicellular cells will have a specialized function, typically do not have to independently gather food and will express target genes selectively rather than all of the genes necessary for survival that a single-celled organism might express.
What are protozoans?
Protozoans are unicellular, single celled micro organisms. Usually by themselves, but they sometimes form colonies. These organism get their food from their surroundings, and tend to live in a marine environment or fresh water. The official definition of the word protozoans is "a single-celled microscopic animal of a group of phyla of the kingdom Protista, such as an ameba, flagellate, ciliate, or sporozoan."
Microscopic single celled organism that has no defined memebrane bound nucleus would fit into which 2 kingdoms?
The microscopic single-celled organism without a defined membrane-bound nucleus would fit into the kingdoms Bacteria and Archaea. These organisms are known as prokaryotes and lack a true nucleus, making them distinct from eukaryotic organisms found in the kingdom Protista, Fungi, Plantae, and Animalia.
How are cells in multi-celled organism similar and different in cell in a single cell organism?
Both!All cells in a multicellular organism are identical genetically. This is because they are all formed from a single original cell (in humans, for example, the zygote) by mitosis.However, as the organism develops, some cells will become different in shape and function; this is called differentiation, and it allows different cells to specialize for different roles. Some examples in humans: nerve cells, muscle cells, white blood cells (and there is more than one kind of each of these).
What is the general characteristics under phylum protozoa?
Protozoa are a diverse group of single-celled organisms with eukaryotic cells. They typically move using flagella, cilia, or pseudopods and are found in various habitats, including freshwater, marine environments, and soil. They can be free-living or parasitic and play important roles in nutrient cycling and food webs.
How do single celled organisms repraduce?
Single celled organisms reproduce asexually, they can either reproduce via sharing DNA or splitting to 2.
Is an anteater a single-celled organism?
No. Single-celled organisms are too small to see without a microscope. An anteater can be mroe than 2 metres head to tail.
How do many celled organisms reproduce?
2
How do parasites vary?
Parasites are of different types and range in size from tiny, single-celled, microscopic organisms (protozoa) to larger, multi-cellular worms (helminths) that may be seen without a microscope. The size ranges from 1 to 2 µm (micrometers) to 2 meters long.
How many parents are there in sexual reproduction in bacteria?
most bacteria (and single celled organisms at that) are asexual in that they reproduce by themselves. There are some bacteria with 2 parents tho
What 2 creatures never sleep?
actually, its not only two creatures... reptiles, fish, and single celled organisms never sleep but they might go through times where they are inactive

Which term describes organisms that are made up one cell?
A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, in contrast to a multicellular organism that consists of multiple cells.Prokaryotes, most protists, and some kinds of fungi are unicellular.
What is unicellular and multicellular oragism?
uni-cellular means single celled ( uni itself means singular ) organisms . And they are also of two types - 1. eukaryotic cells 2. prokaryotic cells . While multi-cellular are those which comprise of many single cells which are joined together and they also work together to keep the organism alive.
