Meiosis & Sexual Reproduction
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.

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

Human Life Cycle Mitosis & Meiosis
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.

What's the Difference between Mitosis & Meiosis
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 Book review- Botany for Gardeners
From the time we are toddlers, we absorb and bury snatches of info about the lives of plants. Over time our brains lose track of the some of the nitches where that info is stored. Often information from two different sources is conflicting. Very often the knowledge is spotty, and is not organized well for good understanding. However with a book like Brian Capon's <i>Botany for Gardeners</i> we can gain a complete and accurate picture of the world of plant science and gain the power to move our gardening to another level. Written for the layman, an excellent volume for both the beginner and the passionate enthusiast, this book is a very readable text that will enhance your appreciation of your gardening experience.
