Join the Amoeba Sisters as they introduce angiosperms (flowering plants) before exploring flower parts, pollination, and double fertilization in angiosperms! This video also talks about the importance of pollinators.

Did you know that bananas are berries, but strawberries aren’t? A lot of thought goes into classifying fruits and vegetables, and it all has to do with anatomy.

Seasonal illnesses from infectious diseases aren’t a new concept, but a few decades ago public health experts began to notice the same behavior in some non-infectious diseases like breast cancer. These patterns have helped us learn a lot...

Join us as we explore flower parts, pollination, and double fertilization in angiosperms. We'll also talk about the importance of pollinators, like bees, and the role they play. 00:00 Intro 1:34 What are Angiosperms? 1:48 Fruit 2:29...

Hank lets us in on the meaning of life, at least from a biological perspective - it's reproduction, which answers the essential question of all organisms: how do I make more of myself? So, sex, how does it work?

Paul Andersen starts with a brief description of asexual and sexual reproduction. He explains how meiosis ensures variation in the next generation. He describes the important structures in the male and female reproductive system. He...

Infertility affects 1 in 8 couples worldwide. But in the last 40 years, more than 5 million babies have been born using in vitro fertilization (IVF). How does it work? Nassim Assefi and Brian A. Levine detail the science behind making a...

Forget lab rats — meet the Chinese or striped-back hamster, an unassuming little rodent whose role in research over the years has led to breakthroughs in genetics, pharmaceutics and more!

Hank gets into the dirty details about vascular plant reproduction: they use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot differently...

In this video, Jonathan from the Institute of Human Anatomy discusses 5 organs/structures that human beings can live without.

Learn about photosynthesis and the parts of a plant with fun animation for students of all ages, especially fourth graders. Learn how plants make their food using water, air, light, and nutrients. Covers chlorophyll and photosynthesis...

The video explains the female reproductive cycle, including changes in hormone levels and the process of ovulation. It also compares the hormone levels of men and women, highlighting the significant fluctuations women experience...

Several important plant activities including photosynthesis, reproduction, growth and germination are investigated in this series of videos. Students will learn how these processes are related to the structure of plants. Important...

In this De-Natured segment of Nature League, Brit breaks down a recent scientific journal article about the effects of childhood trauma on adult sperm cells of mice and men. Article citation: Dickson, D.A., Paulus, J.K., Mensah, V., Lem,...

In this Nature League Field Trip, Brit goes on a Montana safari at the National Bison Range and shares some local stories of how species have persisted over time via reproduction.

In this video, Justin and Jonathan from the Institute of Human Anatomy discuss the basics of embalming and dissecting, as well as introduce the viewer to each cadaver in the lab.

This engaging video program uses colorful animations and on-location footage to illustrate some of the amazing ways plants reproduce. The reproduction processes in bryophytes, ferns, gymnosperms, and angiosperms are highlighted....

This video explains what endometriosis is, its prevalence, and the theories behind its cause. It also discusses the different types and stages of endometriosis, as well as its impact on fertility and menstrual cramps.

This video explains the science behind period cramps by examining the female reproductive system. The uterus grows a thick inner lining called the endometrium every month in preparation for pregnancy, and if pregnancy doesn't occur, the...

This video discusses the process of ovulation in the female reproductive cycle, including the role of follicles and hormones such as follicle-stimulating hormone and luteinizing hormone. It also explores the function of estrogen in...
