The process of photosynthesis requires water, carbon dioxide, sunlight and chlorophyll. The only cells that are capable of photosynthesis are the ones that contain chloroplast.
Plastids are cell organelles that are double membrane and generally found in plants and algae.
There are three types of plastids, namely
The cell that have chloroplast can perform photosynthesis, because it is the chlorophyll that enables this process by absorbing sunlight.
Thus, the only cells that are capable of photosynthesis are the ones that contain chloroplast.

Explanation:
Genetic drift is a phenomenon which changes the allele frequency of a population due to a natural catastrophic which is random. The phenomenon occurs in the small population and chances of change in the allele frequency are very less in the large-sized population.
The size of the population is affected by the mating also and the monogamous species have more genetic diversity compared to the polygamous species but the polygamous mate to maximize the chances of breeding. These lead to the change in the genetic drift and both the polygamous and monogamous species will be affected by the drift process.

Answer:
Biodervasity.
Explanation:
The term refers to the variety of life on earth.It demonstrates the extent of variation at different levels of species,genetic and ecosystem in a community of organisms.
It not equal in its distribution on earth;but rather varies with the type of ecosystem available and the distribution of biotic and abiotic factors in the ecosystem. For example;
It is highest in the Tropics,due to the species richness and diversity of the region. However, it varies in other ecosystem based on species diversity peculiar to parts of the region .e.g it is highest in the marine ecosystem along the coast of abundant temperature for primary producers.

Answer:
same DNA bases and HGT
Explanation:
Even though we are different species, so much as different kingdoms, the DNA is always going to be the molecule that contains our genetic information and constitute our genes. This molecule is made up by the same structure: a sugar, a phosphate and a base like adenine, guanine, cytosine, thymine. Regardless if its a human, bacteria, fungi or a plant cell we all share this in common.
It is well known that we acquire our whole set of genes from our ancestors but some studies have shown that we also acquire genes from other organisms and its called horizontal gene transfer (HGT). HGT involves the movement of genetic material between different species. Since we've been sharing the world with a lot of prokaryotic organisms we might have experienced the HGT at some point of the evolution, and since our genetic material is made up of the same molecules, we can have the same subsets of genes working in both organisms.
Answer:
The subset of genes shared by humans and prokaryotes originates from a common ancestor and has been retained over billions of years of evolution.

This is was the right answer on my teachers test.
