Question

Base your answers to parts a and b on the diagram below and on your knowledge of biology. Part A: explain why process 2 is important to sexual production. Part B: identify processes 1 and 3. State one difference between the cells produced by process 1 and the cells produced by Process 3.

Answer 1

1. Please find the explanation to Part A below

2. Process 1 is meiosis while process 3 is cell division

3. Cells produced in process 1 are haploid while cells produced in process 3 are diploid

Step-by-step explanation:

PART A:

The process 2 described in the attached image is called FERTILIZATION. It is the process whereby male gamete (sperm) unites with the female gamete (egg) to yield a ZYGOTE. This process of fertilization is important to sexual reproduction because it is the way the diploid state of an organism is restored after haploid gametes must have been formed via meiosis. In other words, haploid (n) sperm and egg unites during fertilization to yield a DIPLOID ZYGOTE (2n).

PART B:

- Process 1 in this attached image depicts MEIOSIS, which is the process whereby haploid daughter cells (gametes) are formed from the division of a diploid cell. Meiosis reduces the chromosome number of a cell by half.

- Process 3 is CELL DIVISION. The zygote formed from fertilization (process 2) undergoes series of cell division to produce the EMBRYO.

PART C:

The cells produced in process 1 (meiosis) are HAPLOID i.e. contains one set of chromosomes while the cells produced in process 3 (cell division) are DIPLOID i.e. contains two set of chromosomes
