A viroid is an infectious agent that consists of a small strand of RNA and that causes disease in plants.
A plant pathologist discovered an infectious RNA particle smaller than a virus that causes diseases in plants. He called it a viroid. Millions each year are lost by these viroids. These contain only RNA.
A prion is a small infectious particle that contains a misfolded protein. These contain no DNA or RNA. These cause Creutzfeldt-Jakob disease, Scrapie in sheep and Kuru. These are deadly and progressive nerve wasting diseases.A plant pathologist discovered an infectious RNA particle smaller than a virus that causes diseases in plants. He called it a viroid. Millions each year are lost by these viroids. These contain only RNA.These two are the smallest infectious particles. They are not called microorganisms because they are not alive any more than viruses are.
An infectious agent smaller than bacteria and capable of infesting almost all plants and animals is a?
Eukaryota.
NO,Protozoa does not cause diseases in plants.

it causes a number of diseases in animals and plants
Bhendi yellow vein mosaic is a disease that infects plants and causes yellow and green alternating patches on the leaves. Plants that have the disease need to be burned. The disease was first identified in 1924.
yes they can!

By breaking down the skin or surface area they live on. This causes damage that is the sign or symptom of the disease the fungi causes. Fungi are plants, they do this with their roots.

Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns (mottling and discoloration) on the leaves (hence the name). TMV was the first virus to be discovered. Although it was known from the late 19th century that an infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus. Please improve this answer if you know exactly how he discovered this virus.

National trust crossword, im stuck on this too :))) Think it might be smut
malaria is an infectious disease. It affects mainly mammals but can also infect birds, reptiles, and other species. It can even infect plants.
