Mitochondria and chloroplasts are considered semi-autonomous organelles, as they resemble bacteria. They have DNA, RNA and ribosomes, and are capable of synthesizing proteins. They reproduce by binary division. Each organelle has several copies of circular DNA, but its genetic information is not enough to classify the organelle's proteins. For this reason, mitochondria and chloroplasts are divided by two genetic systems, that of the organelle and that of the cell nucleus.
Explanation:
Endosymbiotic theory suggests that mitochondria and chloroplasts evolved when bacteria were phagocyted by an ancestral eukaryotic cell. Acquiring mitochondria is a very important stage for eukaryotes, because thanks to them the ability to aerobic respiration was achieved. On the other hand, chloroplasts arose when some eukaryotes phagocytized photosynthetic bacteria and the symbiotic relationship between them was established.

Sex linked traits can only be held on the X chromosomes, so males only need one while females need two. Since the daughter has it, it must mean the mother is a carrier and has one normal X chromosome and another with the recessive trait (c).
A rose plant gathers energy from the sun. It uses the sunlight in order to carry out photosynthesis. Plants need the sun's light to create their own energy.
