Compare plant and bacterial cells. what is common and what are the differences in their structure? what is the role of spores in the life of bacteria? why without the activity of bacteria life on Earth would be impossible?

1) Both plant and bacterial cells have a cell wall. In the first case, it is formed by cellulose, in the second, by murein. In a bacterial cell, there is no real nucleus and only one circular chromosome, and there are no membrane organelles (for example, mitochondria). In a plant cell, these elements are present, and the chromosomes are linear, there are several of them. Bacteria can also have plastids that carry a small circular DNA.

2) Spores are formed under unfavorable conditions. They have a thick wall that protects bacteria from environmental conditions, and in this form, the cell can remain viable for a long time, while being dehydrated.

3) Bacteria are both reducers and producers. They decompose organic matter and return substances into circulation, and can also transform them into a form accessible to other organisms. Also, thanks to the activity of bacteria, many minerals are formed, for example, oil.
