Textbook Question
Chapter 28, Problem 5TYU

Students have asked these similar questions
Plasmogamy is the fusion of(a) two haploid cells including their nuclei.(b) two haploid cells without nuclear fusion.(c) sperm and egg.(d) sperm and two polar nuclei.
Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.
The process by which haploid cells are produced from diploid cells is called
A( sexual reproduction.
B) meiosis
C) gameoto reduction
D) mitosis
Why must the life cycle of sexually reproducing species alternate between haploid
and diploid stages?
A) Mitosis must occur at some point in the life cycle to prevent a doubling of
chromosomes in each generation.
B) Meiosis must occur at some point in the life cycle to prevent a doubling of
chromosomes in each generation.
C) Mitosis must occur at some point in the life cycle to prevent a reduction of
chromosomes in each generation.
D) Meiosis must occur at some point in the life cycle to prevent a reduction of
chromosomes in each generation.
