Unicellular algae or Amoeba reproduction is synonymous with growth ie increase in number of cells. In simple multicellular organisms eg Hydra every cell may also get oxygen through diffusion from environment. Video includes the modern cell theory and p.

Unicellular organisms reproduce by the following ways. Unicellular or multicellular autotrophic organisms Contain chlorophyll pigment and carry out photosynthesis For example. In this a single cell divides giving rise to two daughter cells.

Unicellular-composed of 1 cell OR Multicellular- made of many cells. Cells can have an irregular shape such as an amoeba or a well-defined shape such as an RBC. A single-celled creature can carry out all of the functions that multicellular organisms can.

Iii Spore formation also by multicellular organisms b Asexual reproduction by multicellular organisms. A unicellular organism also known as a single-celled organism is an organism that consists of a single cell unlike a multicellular organism that consists of multiple cells. Oxygen passes into it through diffusion.

I Fragmentation and Regeneration. It is called the fission. Similar functions in multicellular organisms are carried out by groups of specialised cells forming different tissues.

Which are free-living unicellular or colonial flagellates and the parasitic Ichthyosporea also known as Mesomycetozoea. The unicellular organisms reproduce by binary fission. Cells can be Eukaryotic or Prokaryotic.
