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. meiosis mitosis • meiosis sexual reproduction • types of cell division • sex cells sperm egg • gametes fertilization
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. cell division • mitosis • meiosis • asexual reproduction • sexual reproduction
Mitosis & Meiosis Comparison This article series provides information of how mitotic and meiotic cell division differ and how these processes are integral to the human life cycle. mitosis meiosis comparison • compare mitosis meiosis • meiosis mitosis difference • human life cycle • somatic cell division
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. human life cycle • mitosis meiosis • mitotic meiotic cellular division • sexual reproduction • fusion of gametes
Cystic Fibrosis Explains how one acquires Cystic Fibrosis as well as characteristics of the disease. It also explains that the disease is not contagious and is inherited genetically. cysticfibrosis • meiosis • haploidnumber • chromosomes • phenotype
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). mitosis meiosis • cell division • mitotic meiotic • sex cells gametes • zygote fertilized egg
Ploidy: Diplod and Haploid Humans are diploid organisms with two sets of homologous chromosomes, but we also contain haploid sex cells with one set and half the number. ploidy • haploid • diploid • 2n • chromosome number

Cytoskeletal Intermediate Filaments The tough fibers that span cells and hold the nucleus together are intermediate in diameter between thin actin microfilaments and thick microtubules of the cytoskeleton. intermediate filament • cytoskeleton • keratin • hair and nails • tensile strength
The Life Cycle of a Moss 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. life cycle • moss • spore • reproduction • sex
Understanding the season of abundance June is an intense period in the cycle of life and death. Over-production can puzzle and even appall us, but plays an essential role in the strength of our environment. guelph • environment • warbler • canada geese • canada goose
What Is a Genetic DNA Mutation? A mutation is a rare change in a gene's DNA sequence that can result in a defective cellular protein. This article covers the basics of genetic mutation. what is a genetic mutation • what is a gene mutation • what is dna mutation • genome mutation • mutated gene

Chromosomes & Sister Chromatids 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. sister chromatids • cell nuclear division mitosis • duplicated homologous chromosomes • eukaryotic cell cycle • parent daughter cell
The Process of Pollination in Flowering Plants Once female and male gametes (egg and pollen) have formed, pollination is the process that brings them together so fertilization may occur. pollination in flowering plants • pollination in angiosperms • sexual reproduction in flowering plants • sexual reproduction in angiosperms • pollen formation

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. botany • botany for gardeners • plant science • plant anatomy • photosynthesis |
