Building Blocks of Life EssayPart 1 Mitosis and Meiosis Short-Answer Response employment Ch. 5 of BioInquiry and the Comparing Mitosis and Meiosis video as resources for Part 1 of this assignment. Write 75- to 100-word answers to the following questions.Why are the process of mitosis and meiosis both big to a living universe?Both mitosis and meiosis processes are extremely important because they are the air division of chromosomes and without this division reproduction would not occur. Cell division plays an important role in the life cycle of a cell allowing the cell to grow, develop and then reproduce. If these processes did not occur then the cells would eventually exit out and without the ability to be replaced by new cells then the host would die as well.When would an organism need to undergo the process of mitosis? Meiosis?An organism would need to undergo the process of mitosis in order to repair damaged cells or to start a new cell life cycle finished cellular divi sion. All cells need to be replaced on the regular basic within a living organism the cells divide and create new cells. An organism would need to undergo the process of meiosis when it needs to produce cells that are designated for sexual reproduction, such as egg or sperm cells within humannessWhat would happen if meiosis did not occur?If meiosis did not occur then haploid cells would not be made resulting in the cell being unable to reproduce. Meiosis I reduces the number of chromosomes by half so that when fertilization occurs the number ofchromosomes would be reestablished. During meiosis II the daughter cell is a unique variation of its parent cell while still only having one pair of chromosomes.Part 2 Photosynthesis and Cellular Respiration Matrix nail the matrix.
