Cell wall: strong; supporting layer around the cell membrane in plant cells
In a deep wound, there might be a few layers of tissue that need to be rebuilt because they were lost. In this rebuilding process this pebbly texture can be seen and it indicates that granulation is taking place (that's the process). Granulation is when small blood vessels and capillaries start to develop vertically to the outside part of the wound, being supported by connective tissue, and surrounded by cells of many other types for different purposes, such as immunitary functions or specialised tissue functions. This tissue growing is characteristic of healing and it presents this granulated/pebbly texture to it.
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp
