A General Outlook on Meiosis and Mitosis Processes

Compare and contrast mitosis and meiosis. Think phases, starting and ending products, chromosome numbers, the purpose of each, and the cell types that complete each type of division. Be sure to do a DIRECT compare and contrast, and write in paragraph form - Mitosis involves one cellular division resulting in identical daughter cells while meiosis involves two cellular divisions resulting in different daughter cells. Meiosis produces four haploid cells while mitosis produces two diploid cells- this ensures genetic diversity by sexual reproduction in meiosis and cellular reproduction and production of general growth products in mitosis. The chromosome number also ...

Q1. Explain the regulation of the cell cycle

Every cell is regulated by particular checkpoints to ensure that the daughter cells are exact duplications. This is to help guarantee that cell mutations are not passed on to the next generation of cells. In eukaryotic cells, there are three main checkpoints. These are points at which cell replication can be halted until certain conditions are met (Boundless, 2016). The first checkpoint is near the end of the G1 phase. It is here that DNA gets evaluated and checked for damage. If damage has occurred, it either gets corrected or gets prevented from moving on to the next phase ( ...

Abstract

This examination paper acknowledges the spectacular diversity of reproductive adaptations for survival of various categories of land plants. It describes a typical life cycle of a land plant that reproduces via spores. It also identifies the different parts of Plant organs and their functions such as cell organelles, parts of a land plant, and epidermal cells. A microscope is an important tool for examination of biological specimens, including cell’s internal structures called organelle and is important in magnifying the focused area. Plants are classified into four main groups, namely, ferns, mosses, flowering and confers. This paper finds that ...

Chapter 9

Question 1

Binary mission in prokaryotes Mitosis and Meiosis in eukaryotes Question 2 The development of embryos as well as the growth and development of bodies. Important in asexual reproduction. Question 3 The term cell cycle refers to an ordered set of events leading to cell growth and division into two daughter cells.

Question 4

Interphase is a phase of the cell cycle characterized by the absence of cell division. During this phase, the cell obtain nutrients, the organelles duplicates, protein synthesis takes place, and cells duplicate its genetic material (its chromatids). The genetic material is located in the nuclei of ...
