Articles related to "Sexual Reproduction"

Some living things reproduce by cloning; producing offspring that are genetically identical to the parent. Organisms that procreate sexually create genetic novelty.

Meiosis, a type of cell division, results in production of gametes (eggs & sperm). Genetically unique sex cells combine at fertilization to form one-of-a-kind offspring.

Some animals have males and females, some are hermaphrodite, and some have no sex at all.

Seeds are basically embryos.

Mammals generally invest heavily in raising their offspring and this determines how they choose their mates and also how often they can breed.

Once female and male gametes (egg and pollen) have formed, pollination is the process that brings them together so fertilization may occur.

Genetically modified organisms (or GMOs) are organisms which have been modified using means other than sexual reproduction to introduce DNA from another species.

A definite asexual or sexual reproductive cycle is usually a prerequisite for the success of a species. Mycelia sterilia have found a way to do without either.

Fungi, mosses, lichens, and ferns are among the plants that produce spores rather than seeds as their vehicles of reproduction.

This article series provides information of how mitotic and meiotic cell division differ and how these processes are integral to the human life cycle.

While all flowering plants reproduce sexually, there are some species that are able to fall back on vegetative reproduction if needed.

Toxoplasma gondii affects many different species, but it's a cat parasite. Cats spread it while they are acutely ill.

Here are links to free worksheets that can help science educators assess students' understanding of cell division, DNA transcription and translation.

It all begins with the fusion of a haploid sperm cell provided by the father and the haploid ovum of the mother. Gametes unite when the nuclei of sperm and egg merge.

New study demonstrates that genes recognize other genes that have similar base pair sequences, a discovery that can help us understand DNA repair and genetic diversity.

The distinction between species of sexually reproducing organisms is quite clear, but how are the lines drawn for organisms, like bacteria, that reproduce as clones?

An exhibition of anatomical models and health-related items from the early 18th, 19th and 20th Centuries reveals Victorian attitudes to health, disease, death and morals.

Spores of a moss can endure years of draught, travel hundreds of kilometers and wait silently for the day they germinate and create a new generation of their species.

Fungi have a complex life cycle, and mushrooms are no exception. Mushroom reproduction includes both sexual and asexual reproductive stages.

The Laboratory Stick Insect has unusual reproductive behaviour.

For most people, yeasts, molds, and mushrooms are the most well-known members of the fungal kingdom.

Genetics is concerned with how traits are passed on through generations. This information, genetic material, is stored inside cells, working units that make up organisms.

Children are often fascinated by the world around them and the many inventions and objects they see everyday. Encourage their curiosity with this selection of books.

When is DNA considered a chromosome? What is a sister chromatid and how does it differ from a chromosome? The article unravels some of the lingo of DNA.

Germ Theory is the concept that microorganisms can cause disease, and this theory is the foundation of modern medicine. Here is a summary of some key discoveries.

DNA paternity testing makes it possible to, with a very high degree of certainty, determine the identity of a child's biological father. Here's how.

Genetics can be explained in simple language, and can also be demonstrated through fun activities such as comparing inherited traits or extracting DNA in the kitchen.

There are only two basic types of cells, primitive prokaryotes and the more complex eukaryotes. Here are the main features that distinguish these cell types.

Many permanently diachronic fish are commonly known to the saltwater hobbyist, but the angelfish from the genus Genicanthus may be the most desirable of all.

As the sole members of the subkingdom Parazoa, sponges represent the lowest level of organized animal life.

Mitosis is how the cells of our body make more cells for growth, development and repair. Meiosis is how our body makes sex cells, or gametes (eggs or sperm).

A discussion of the basic characteristics of corals-Taxonomy, Anatomy, Ecology, Food and Feeding, Life Cycle, and Associated Fauna and Flora.

Reading about parasites can be confusing because of all the specialized words that scientists use. This brief parasitology glossary can help.

The assertion that life can instantaneously arise from nonliving matter is called spontaneous generation. Here are the critical experiments that busted the myth.

In North America nearly all gymnosperms display an evergreen tree body form and produce seeds within hard comes.

In order for organisms to grow, develop and maintain life, cells must divide. Cellular division involves the basic stages of interphase, nuclear division and cytokinesis.
