Q1:Why is reproduction essential for organisms?
Reproduction is a fundamental feature of all living organisms. It is a biological process through which living organisms produce offspring’s similar to them. Reproduction ensures the continuance of various species on the Earth. In the absence of reproduction...
1. Reproduction in Organisms
Biology in essence is the story of life on earth. While individual organisms die without fail, species continue to live through millions of years unless threatened by natural or anthropogenic extinction. Reproduction becomes a vital process without...
Green algae have many similarities to land plants. It has many variety body types and the multicellular forms do not have cells separated into tissues, which is what divides green algae from land plants. Green algae are a very diverse group of freshwater algae. Many green algae form long filaments. The...
*1.0 What *are *Fung*i? Fungi contain lack of chlorophyll, never from tissues and all parts of the body consist entirely of a system of tubular cells called mycelium. The vegetative part may not be colnspicusous because it grows under the soil surface or inside a host. The fruiting body is the conspicuous...

Conjugation | A process in which there is a transfer of genetic materials between two cells |

Introduction to Cellular Reproduction
This guide is designed to provide you with an overview of the important processes involved in the reproduction of cells. Cellular reproduction is a process by which cells duplicate their contents and then divide to yield two cells with similar...
The Key Roles of Cell Division
1. Explain how cell division functions in reproduction, growth, and repair.
Reproduction – enables sexually reproducing organisms to develop from a single cell
Repair – allows for replacing of cells that die from normal wear and...
in which parthenogenesis reproduction in vertebrates is beneficial
Sexualreproduction is regarded as the most beneficial way to produce a lasting lineage that can adapt to changing environments and evolve to greater complexity. However, some species use asexualreproduction to sustain their population...

PART 1 : Asexual vs. SexualReproduction [ 4 marks ]
- Discuss the differencesbetween, and the advantages and disadvantages of sexual and asexualreproduction :
SEXUALREPRODUCTIONSexualReproduction is the formation of a new organism from two parents...
A) regeneration. B) sexualreproduction. C) spontaneous generation. D) asexualreproduction. 2) Which of the following statements regarding sexual and asexualreproduction is true? A) Only offspring from asexualreproduction inherit traits from two parents. B) Sexualreproduction is more likely to increase...

Chapter 13: Meiosis and Sexual Life Cycles
1) What is a genome?
A) the complete complement of an organism's genes
B) a specific sequence of polypeptides within each cell
C) a specialized polymer of four different kinds of monomers
D) a specific...
II. Mitosis and Meiosis are both correctly described as nuclear division; they are never correctly called cell division, or any kind of reproduction. It is possible (and often quite normal) for nuclei to divide when cells don't. And organisms reproduce; nuclei and cells divide.
Main article: Evolution of sexualreproduction
It is considered that sexualreproduction in eukaryotes first appeared about a billion years ago and evolved within ancestral single-celled eukaryotes. The reason for the initial evolution of sex, and the reason(s) it has survived to the present, are...
Organisms of many species are specialized into male and female varieties, each known as a sex. Sexualreproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent. Gametes can be identical in form...
