Answer: (A) Only differentiation is a process that results from stem cell division.
Explanation:
Cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Differentiation occurs many times during the development of a multicellular organism. The organism changes from a single zygote to a complex system of tissues and cell types.
A because Only plant cells have chloroplasts
Answer:
Chloroplast and mitochondria
Explanation:
Chloroplasts are organelles present only in plant cells and algae in regions that become illuminated. They are green in color due to the presence of chlorophyll and are responsible for photosynthesis. Chloroplasts produce ATP in the presence of sunlight and therefore the heaviest fractions should contain these organelles.
Mitochondria are cellular organelles related to the process of cellular respiration. They are often referred to as “powerhouses” of cells because, through the cellular respiration process, a large amount of ATP is generated. Mitochondria do not need light to produce ATP, so it is likely that these organelles are present in the lightest fractions.
