Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.

Explanation:
Mineral growth occurs due to the accumulation of food substances in the cells which in turn increases the volume of the protoplasm in the cells. This increase in the volume of cells results in growth.
It made me feel sad but also happy that they didn’t chose
Chloroplast are an organelle in the plant cell that converts sunlight into energy and uses it for the growth of it.
It stores extra water for later use.
Hope it helps!!!
