Answer:
It is usually of uniform thickness. (Ans. E)
Explanation:
In the plant cell wall primary cell wall is existing between the mid lamella and the secondary cell wall. The structure of the primary cell wall is thin, and flexible in nature and they are made up of pectin, hemicellulose, cellulose.
The primary cell wall is the part of the cell wall that has the capability to enlarges the layers by the mechanism known as an acid growth mechanism, with the help of this mechanism plant cells grow via plant cell wall enlargement at a poor pH level.
Answer:
The correct answer is - scanning electron microscope.
Explanation:
SEM or a scanning electron microscope is that produces an image by an electron beam over the sample surface to scan. The electrons of the beam interact with the sample producing various signals that allow providing information about the composition and topography of the individual sample. The magnification of the SEM is in between 20X to 30000X
Thus, the correct answer is - scanning electron microscope.
The genotype would be Round Yellow.
