Khan Academy: Biology: Mitosis, Meiosis and Sexual Reproduction

Biology learners highlight the features of asexual and sexual reproduction in this life cycle worksheet. They take an in-depth look at the role of chromosomes in meiosis and the overall process of reproduction. 

Young biologists define reproduction vocabulary terms, answer critical-thinking questions, label a diagram of the human life cycle, and complete a chart comparing mitosis to meiosis. This is a well-balanced worksheet. Even though it...

Why do some organisms reproduce sexually, others reproduce asexually, and some both? Biology scholars examine the pros and cons of sexual and asexual reproduction through a short, informative video. The resource offers great examples of...

Gain an understanding of mitosis, meiosis and sexual reproduction. Vocabulary introduced gametes, zygotes, and haploid / diploid numbers.

Learn the basics of acids, bases, proton concentration, the pH scale, and buffers in this article.

This video will explore the pH scale. See some examples of how to calculate the pH of water, orange juice, and bleach. [11:37]

Learn about binary fission, budding, mitosis, fragmentation, parthenogenesis and sexual reproduction. [8:42]

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,...

An explanation of the biological classification of organisms. [12:41]

An explanation of the function of APC and MHC class II cells. [11:33]
