Unicellular organisms contain only one cell. Within a single cell, you can't have levels of organization like tissues, organs, and organ systems.
An organ is one structure that performs a specific function(ex. stomach) and an organ system is a group of organs(ex. digestive system)
No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .
The way it goes is this: one type of cell makes tissues, many tissues make an organ. Many organs make an organ system and many organ systems make an organism.
The fungi is related to the mushroom.
Yes, the nervous system is considered one of the organ systems in animals.
There is only one function that both organ and plant systems have. The one thing organ systems and plant have in common is tissues.
One of the unicellular organisms is bacteria.
