Note about the question:
Probably there are options for this question, but I failed in finding them. However, in the explanation box I will explain the reason for the lack of white flowers in the F1.
Answer:
The purple phenotype is dominant over the white phenotype. The allele that expresses the purple color is dominant and, in a heterozygous state, hides the expression of the recessive allele that expresses the white color. Principle of dominance.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
Answer:
The concentration gradient is the driving force.
Explanation:
Passive transport of substance occurs when they are moved from the region of their higher concentration to that of their lower concentration. The concentration gradient is the difference in the concentration of substances between two regions or across the membrane. The concentration gradient of substances drives their passive movement. The passive movement of substances does not use metabolic energy. Simple diffusion and facilitated diffusion are two examples of this transport.
Answer: organic compound

Sugars pass from cell to cell in the leaf starting in the symplast of the mesophyll; they move through the symplast or apoplast of other cells and finally pass into the symplast of the sieve tube element
In symplastic pathway the sugar will move through the cytoplasm of the cell and pass on to the other cell through the plasmodesmata.
In apoplastic pathway the sugar will move through the cell wall and intercellular spaces and does not cross the cell membrane.
When the sugar are synthesized by the leaves first it will move through the symplast of the mesophyll cells. Then sugar will be travelling either through symplastic or apoplastic pathway in other cells and pass through the sieve tube elements in symplastic pathway
