Question

It is difficult to use the criterion of interbreeding to define species of unicellular organisms . why ?

Answer 1

unicellular organisms can't interbreed because they to have different chemical structures and properties. They are part of a different species and according the the definition of a species, they would not be able to interbreed.

Answer 2

Answer:

It is difficult to use the criterion of interbreeding in unicellular organisms because they have different chemical structures and properties.

Explanation:

What is interbreeding?

• Interbreeding refers to the production of offspring through the mating of closely related organisms (genetically).
• Livestock breeding, plant breeding, etc. are examples of interbreeding.
• The populations that can interbreed are called species.
• They have two hybrids as a result of which offspring are produced by sexual reproduction.
• Most of the unicellular organisms reproduce asexually. Thus, interbreeding is not possible.
• Since they have a single cell, they reproduce through processes like binary fission like in bacteria and amoeba or budding like in yeast.
• It is through a single parent that the daughter cells are produced.
• Examples of unicellular organisms include: protozoa, algae, fungi, bacteria, etc.
