Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.
On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any
external injuries.
I hope that helped
Answer:
A) chromosomes is the correct answer.
Explanation:
Chromosomes are present in nuclei of animals and plants and they are composed of protein and DNA.
functions of chromosomes
- Chromosomes are required for the formation of daughter cells, replication and cell division process.
- Chromosomes carry the genetic material called DNA that provides genetic information to carry out the different cellular processes and functions.
I would say B because A doesn’t have a ring to it.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
Here is your Answer. But is there options?
