For organisms like algae and other protists, certain bacteria, and plants, photosynthesis is a critical process. Why is the process of photosynthesis essential for organisms like these to perform?
All animals depend on plants for survival as they are the only producer that provides others feeds on the trophic level or food chain, without photosynthesis plants would not be able to produce food which is at the detriment of animals
Sexual reproduction happens when there is the involvement of two parents to give rise to the offsprings.
For the production of offsprings, each of the parents produces a haploid gamete and it is by the fusion of these two haploid gametes that a diploid organism is produced.
In the given situation, there are 19 chromosomes present in the haploid gametes this means that a diploid individual will have 2X19 = 38 chromosomes.
Now the underground stem cells are not gametes but somatic cells and the somatic cells are diploid and hence, they will have 38 chromosomes.
