Pathway For Sperm and Egg Cells to Fertilization
In this video, we will examine the precise site of fertilization and then follow the physical path of the secondary oocyte (egg) and sperm cell (spermatozoa) to fertilization.

The Life Cycle of Fern Plants
This clip demonstrates, step by step, the process of reproduction in ferns.

Hormones and Sexual Behavior
We've already learned about hormones in the context of the endocrine system, but now let's get a closer look at how these influence the development of sexual characteristics as well as sexual behavior. How and when does this happen? How...

What is Zygotic Cleavage?
In this video, we explore how the zygote undergoes a variation of mitosis called cleavage.

Stages of Animal Development: Cleavage, Gastrulation, Organogenesis
Before diving into animal diversity, we need a bit more information about animal development, as it will help us understand what we're looking at later. We know that animals reproduce sexually, so a sperm fertilizes an egg to yield a...

Fertilisation and Implantation
It explains the process of fertilisation and describes how the zygote gets implanted in the uterus after fertilisation.

Coupling of Folliculogenesis & Oogenesis
In this video, we see how various stages of oogenesis correlate side-by-side with folliculogenesis.

Angiosperms: Flowering Plants
We just learned about gymnosperms, and the incredible evolutionary advantages they had over their ancestors. But the next leap forward for plants was even more impressive. Angiosperms are flowering plants, so any plant with flowers or...

Sexual Reproduction in Animals
It explains the sequence of events taking place during sexual reproduction in animals. i.e. Gametogenesis; fertilisation and embryonic development.

The Introduction to the Alternation of Generations
Plant Reproduction Set: 8. This clip explains how plants exist in two alternating forms: diploid sporophyte generation and a haploid gametophyte generation.

Introduction to Spiralia and Lophotrochozoa
It's time to start digging into Nephrozoa, which is going to take a really, really, really long time to cover. The first major clade within that we will tackle is Spiralia. This includes well-known phyla like Mollusca and Annelida, but...

Alteration of Chromosome Number and Structure
We've already learned about certain kinds of modification to the genome, namely in the way of mutations that can occur to specific base pairs, or frameshift mutations when base pairs are deleted or inserted. But there can also be...

An Introduction to Embryonic and Fetal Development
Developmental Set: 1. This clip introduces the early stages of embryonic development and the process of cellular differentiation that gives rise to organ systems during fetal development.

The Human Reproductive System
Throughout this series, we've learned all about the various systems of the human body. But how do humans make more humans? As a child might ask, where do babies come from? Suppress the immature giggles if you can, human reproduction is...

The Stages of Human Development: From Fertilization to Birth
This video provides a concise overview of human embryonic development, starting from fertilization and the formation of a zygote, to the development of germ layers, major body systems, and finally the birth process. It emphasizes the...

Understanding the Male Reproductive System
The video explains the differences between the male and female reproductive systems and focuses on the production of sperm in males. It describes the process of sperm production in detail, including the role of testosterone, the anatomy...

Sexual Reproduction in Flowering Plants: Fertilization, Seed and Fruit Development
Plant Reproduction Set: 2. This clip explains the process of double fertilization in flowering plants and looks at seed and fruit development.

Reproductive System
Begin looking at reproduction by contrasting sexual reproduction with asexual reproduction. Sexual reproduction gives us genetic variation as meiosis creates brand new chromosomes through cross over. Male and female anatomy is covered,...
