Question

How are diseases caused in plants

Answer 1

$\huge\mathfrak\red{Answer:-}$

Disease caused in plants by Pathogens.

Explanation:-

plant diseases are caused by living (biotic) agents, or pathogens. These pathogens can be spread from an infected plant or plant debris to a healthy plant. Microorganisms that cause plant diseases include nematodes, fungi, bacteria, and mycoplasmas. We also classify viruses and viroids as biotic agents because they must have living cells for reproduction and are composed of nucleic acid and protein. Some higher plants that produce seeds are parasitic on other plants and are considered to be pathogens.
