Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities. In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.

Why don't cyanobacteria and bacteria reproduce by mitosis? Because:

AVprozaik [17]

Answer:

They do not contain chromosomes. (Ans.C).

Explanation:

Cyanobacteria also known as blue-green algae, they are heterogeneous group of photosynthetic prokaryotic organisms. Like prokaryotes such as bacteria, cyanobacteria lack endoplasmic reticulum, mitochondria, membrane bound nucleus, and Golgi apparatus. Bacteria are simpler than other organisms, and single celled microbes.

Both bacteria and cyanobacteria reproduce through the asexual method either by binary fission in unicellular, multiple fission in colonial form or by spore formation, and fragmentation in filamentous species.
