Question

What is common to Bacteria, Mosses, and Fungus?

Answer 1

Bacteria:

1. They are unicellular, autotrophic, or heterotrophic.
2. They have a cell wall, that does not contain cellulose or chitin.
3. They have a cell membrane and cytoplasm which contain glycogen granules.
4. There is no nucleus, only DNA in the form of a single, coiled chromosome.
5. Examples: E.coli, Thiobacillus, etc.

Mosses:

1. The common bryophytes are mosses which are members of the phylum Bryophyta.
2. Mosses are very small green photosynthetic plants.
3. They grow usually in moist, shady habitats.
4. They have no true stems or leaves.
5. The main moss structure is the gametophyte, which consists of moss, stem, and leaves.
6. Examples: Funaria, Polytrichum, etc.

Fungus:

1. Cells are eukaryotic and these are heterotrophs.
2. All cells are composed of a cell wall containing chitin, not cellulose-like plants.
3. Except for yeasts, other all fungi are multicellular.
4. Fungus is made up of thin filaments called hyphae.
5. Examples: Yeasts, Rusts, etc.

Hence, the common factor between bacteria, mosses, and fungus is the presence of cell walls.
