Intercellular transportation would not have occurred if there were no plasmodesmata.
Explanation:
Plasmodesmata are intercellular pores connecting adjacent plant cells allowing membrane and cytoplasmic continuity and are essential routes for intercellular trafficking, communication and signaling in plant development and defense
If we want to isolate a species or identify it, we should grow it in a plate with the appropriate media. In this way, it will be much easier to separate a single cell and analyze it by its morphology or study the colony growth.
Stab tubes can be used when we want to study, for example, how a bacteria might grow under low-oxygen conditions. Cells might be inoculated in a liquid media or semi-solid media. We might analyze their growth in the deeper parts of the tubes, where oxygen is very low.
Grow bacterias cultures in agar plates will also allow us to separate the species of interest form other species present in the culture. We might also compare and study differences between species growth.
When growing bacterias on growth plates, they do not last long, as they have more chances of dehydrating. Instead, if we want the culture to survive for a longer-term, we should use stab tubes.
Stab tubes are better to study the motility of different species, which might help us to identify certain bacterias of interest.
Though some cells are bigger than others, they do not scale with size. For example if you look at skin cells on a dog they would be similar in size to a skin cell from a human. When an animal or species is bigger it is usually just made from more cells.
