ASEXUAL REPRODUCTION Asexual reproduction is a mode of reproduction by which offspring arise from a single parent‚ and inherit the genes of that parent only; it is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. The offspring will be exact genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea

HUMAN REPRODUCTION PROCESS SEXUAL INTERCOURSE During this process‚ the erect penis of the male is inserted into the female’s vagina‚ and then either partner initiates rhythmic pelvic thrusts until the male ejaculates semen‚ which contains sperm‚ into the vaginal canal. PREGNANCY This is the time that fetus develops‚ dividing via mitosis inside the female. BIRTH which begins with the fetus being pushed out of the birthing canal. The newborn‚ which is called an Infant should typically begin respiration on

Q1. Why is reproduction necessary in living organisms? If organisms don’t reproduce‚ then after their death‚ there would be no organisms left of their species. Thus their species would perish. Q2. Differentiate between Sexual and Asexual reproduction. |Sexual Reproduction |Asexual reproduction | |1. It is characterized by the fusion of two cells (Gametes) usually coming from

Reproduction in humans Reproduction Reproduction is a characteristic of all living organisms. It is the process that makes more of the same kind of organism. Reproduction is essential in all species to ensure that the species does not extinct. There are two types of reproduction‚ Asexual and sexual reproduction. Asexual Reproduction: Asexual means not sexual. This means that this kind of reproduction does not involve sex. Asexual reproduction is the production of genetically identical offspring from

Plants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have abtained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato‚ farmers will pick the potatoes and cut

Using a microscope and slideshow and based on readings in the lab the following are answers to questions asked in the experiment. Based on the data gathered from observation differences in normal cells and cancerous ones have revealed themselves. Most

Definitions In relation to the topic‚ MacLeod explains social reproduction as the theory that “explains how societal institutions perpetuate or reproduce the social relationships and attitudes needed to sustain the existing relations of production in a capitalist society.” (MacLeod 9) In this definition‚ the societal institutions are places like‚ government offices‚ and schools. These institutions according to him help continue to maintain the status quo by preserving the existing barriers between

Reproduction/Supplies/Entertainment/Labor In the ant colony reproduction occurs at an incredibly fast rate. The life of an ant starts with an egg. If the egg is fertilized‚ the ant will be female‚ if not‚ it will be male. When an egg is fertilized it has four stages it has to go through and develop by complete metamorphosis. From and egg‚ ants enter the larval stage which is particularly helpless‚ because it lacks legs entirely and it can’t care for itself. Food is given to the larvae by

Vegetative reproduction (vegetative propagation‚ vegetative multiplication‚ vegetative cloning) is a form of asexual reproduction in plants. It is a process by which new individuals arise without production of seeds or spores. It can occur naturally or be induced by horticulturists. Although most plants normally reproduce sexually‚ many have the ability for vegetative propagation‚ or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic
