Answer:a. mitosis
Explanation: mitosis is a type of cell division found in somatic cells.
The daughter cells contains the same number of chromosomes as the parent cell.
Mitosis involves four stages namely;prophase, metaphase, anaphase,telophase.
There is also an interphase,of normal functioning of the cells.
Mitosis is important in asexual reproduction , regeneration and replacement of lost cells.
It also causes growth in organisms.
Unlike meiosis , crossing over does not occur in mitosis thus there is no variation in daughter cells
Answer:
The correct answer will be option-B.
Explanation:
Photosystem of a plant is complex pigment-protein molecules which absorbs the light energy required for the formation of a glucose molecule.
Two types of Photosystem are present in the plants which are: P₆₈₀ and P₇₀₀. The 680 and 700 denote the wavelength of the light energy absorbed by the pigment of the chloroplast. The electrons get excited only at their absorbing wavelength.
Thus, Option-B is the correct answer.
