Sounds as if you are describing protists.
A number of algae like Clamydomonas, volvox, oedogonium and bryophytes like riccia, marchantia etc.

What are some characteristics of asexual?
it occurs in somatic cells. mitosis is a mean of it. usually it occurs in simple multicellular organisms
Define unicellular and multicellular?
The difference between unicellular and multicellular lies in the number of cells. Unicellular refers to simple organisms with only one cell while multicellular refers to complex organisms with many cells.
What are the characteristics of organisms in each of the six kingdoms?
Every living creature on Earth belongs to a kingdom. Scientists debate how many kingdoms there are, but most agree there are five. Here is how the five kingdoms are organized.MoneraMonera are single-celled organisms that don't have a nucleus. Bacteria make up the entire kingdom. There are more forms of bacteria than any other organism on Earth. Some bacteria are beneficial to us, such as the ones found in yogurt. Others can cause us to get sick. ProtistsProtists are mostly single-celled organisms that have a nucleus. They usually live in water. Some protists move around, while others stay in one place. Examples of protists include some algae, paramecium, and amoeba. FungiFungi are usually motionless organisms that absorb nutrients for survival. They include mushrooms, molds, and yeasts. PlantsPlants contain chlorophyll, a green pigment necessary for photosynthesis, a process in which plants convert energy from sunlight into food. Their cell walls are made sturdy by a material called cellulose, and they are fixed in one place. Plants are divided into two groups: flower- and fruit-producing plants and those that don't produce flowers or fruits. They include garden flowers, agricultural crops, grasses, shrubs, ferns, mosses, and conifers. AnimalsAnimals are the most complex organisms on Earth. Animals are multi-celled organisms, eat food for survival, and have nervous systems. They are divided into vertebrates and invertebrates and include mammals, amphibians, reptiles, birds and fish. Actually, there are now six kingdoms. The five kingdom was during the 1969 and it included all the bacterias within one group. The five kingdom system is as follows:Monera: Bacteria. They are prokaryotic and unicellular. They are mobile.protista: Protists. They are eukaryotic. Either autotrophic, heterotrophic, or even mixotrophic. They live live as unicellular, multicellular, or even as a colony. Some are mobile while some are sessile.animalia: Animals. Eukaryotic and are heterotrophic. They are all multicellular and are mobile.plantae: Plants. Eukaryotic and mostly autotrophic (some parasitic plants are heterotrophic). They are multicellular and sessile.fungi: Mushrooms, fungus, etc. Eukaryotic and heterotrophic. They are multicellular and sessile.
Why is diffusion insufficient to meet the oxygen requirement for multicellular organisms like human?
In single-celled organisms the entire surface of the organisms is in contact with the environments for the diffusion of substances. In multi-cellular organisms all the cells may not be in direct contact with the surrounding environment. So simple diffusion will not meet the requirements of all the cells.
What are six different species of living things?
Living things can be classified into six distinct species: plants animals fungi protists bacteria and archaea. \tPlants These are multicellular organisms that produce their own food usually through photosynthesis. Examples include trees flowers and shrubs.\tAnimals These are multicellular organisms that rely on other organisms for food. Examples include mammals birds fish and reptiles.\tFungi These are multicellular organisms that absorb nutrients from their environment. Examples include mushrooms molds and yeasts.\tProtists These are single-celled or simple multicellular organisms that can be either autotrophic or heterotrophic. Examples include algae amoeba and diatoms.\tBacteria These are single-celled organisms that can live in almost any environment. Examples include E. coli and Streptococcus.\tArchaea These are single-celled organisms that are adapted to living in extreme environments. Examples include Methanococcus and Halobacterium.These six species of living things encompass a vast array of organisms on Earth.
Is crab multicellular?
No, horseshoe crabs belong to the multicellular, eukaryotic kingdom Metazoa. Single celled organisms are typically very small and quite simple.
Can simple multicellular organisms have organs?
yes,simple multicellular organism can be without organ.e.g sponges
Can multicellular organisms have organs?
yes,simple multicellular organism can be without organ.e.g sponges
How do multicellular organisms breathe?
They obtain their oxygen by simple diffusion.
Differentiate lichens from algae and fungi?
Lichens are a combination of an algae and a fungi functioning together as symbiotic organisms. Algae is an autotrophic organism which may be single or multicellular and consists of chlorophyll to perform photosynthesis. They are simple, eukaryotic organisms. Fungus are multicellular, eukaryotic, heterotrophic organisms consisting of a cell wall made of chitin and root-like structures called hyphae.
Mitosis is the more common type of reproduction among?
Unicellular and simple multicellular organisms
What kingdom does multicellular and motile organisms belong to?
There are two answers to this simple but complex answer, but the answer is fugi and animilia. They are both multicellular and heterotrophic.
What are some characteristics of asexual?
it occurs in somatic cells. mitosis is a mean of it. usually it occurs in simple multicellular organisms
Are protists only prokaryotes?
Protists are not prokaryotic. They are a group of eukaryotic organisms that are quite diverse. They are usually simple in structure.
How might a scientist use cellular biology to classify organisms from simple to complex?
Scientists examine the creatures cell structure to see if it is prokaryotic or eukaryotic. Prokaryotic organisms are usually simple organisms and eukaryotic ones are complex. For example, humans are eukaryotic. Bacteria is prokaryotic.
What transport mechanism do one celled colonial and simple multicellular organisms rely on?
These organisms use simple diffusion as a transport mechanism.This is possible because of the small size of the organisms. Diffusion is effective over small distances but as size increases it becomes less and less efficient.
What is a significant difference between a protist and other eukaryotic organisms?
KINGDOM PROTISTA: These organisms are placed here more because of what they are not than what they are. Kingdom Protista contains all Eukaryotes that are NOT Plants, Animal, or Fungi, more than 50,000 species in all. Kingdom Protista includes unicellular and a few simple multicellular Eukaryotes. Eukaroyotic cells have nuclei and organelles that are surrounded by membranes. The cells of multicellular protists are not specialized to perform specific functions in the organisms.
