What is cellular reproduction?

Answer 1

Cellular respiration, also known as 'oxidative metabolism', is one of the key ways a cell gains useful energy. It is the set of the metabolic reactions and processes that take place in organisms' cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.

Answer 2

There are five steps in the reproduction of a cell. These steps/phases are; interphase, prophase, metaphase, anphase, and telophase. The cell spends most of its time during the interphase, the period between mitoses, which is when a complete set of chromosomes (rod-shaped bodies of genes of DNA), is distributed to each end of the parent cell. During the interphase the cell actively makes new materials and grows. Before mitosis actually begins, the chromosomes are duplicated. During prophase, the first stage of mitosis, the chromatin coils tightly, forming structures that are visible as dark, X-shaped bodies under the light microscope. These are the chromosomes. At this time each chromosome is doubled. During prophase, the nuclear membrane dissolves. Two pairs of organelles, the cntrioles, function during mistosis. Each pair of centrioles migrates toward and opposite end of the cell. Tiny threads of protein called microtubules in the cytoplasm form a spindle-shaped structure that extends throughout the cell. During metaphase, the second phase of mitosis, threads of the spindle attach to the chromosomes. The chromosomes are then positioned along the equator of the cell. Each chromosome is now completely coiled so it appears quite thick. During anaphase, the doubled chromosomes separate and start to move away from one another. The protein threads of the spindle begin to pull one set of chromosome to one end of the spindle and the other set to the opposite end. With the arrival of a complete set of chromosomes at each end of the cell, telophase begins. Telophase is when the cell idvides, forming two cells. The cell begins to constrict around its center and continues to constrict until it has completely divided to form two cells. Each new cell now enters the interphase. That is how cells reproduce.
