The objective of this case study is to train and test a Convolutional Neural Network to detect soil types from images. Deep Learning (DL) is a subset of Machine Learning that uses Neural Network inspired architecture to make...

Paul Andersen explains the current classification system that we use in Biology. He starts with a brief history of taxonomy. He explains how the goal of classification is to reflect evolutionary relationships. He then explains how...

This video explores bacteria, detailing their characteristics, classification, and history. It explains how bacteria, as prokaryotes, are present in diverse environments, from extreme heat to extreme cold. The video also discusses...

This video describes the different species of sorghum and highlights its characteristics, such as its deep and wide-spreading roots, long and solid stem, and compact panicle containing kernels of various colors. It explains the...

The video is an educational session for biology students on the various plant tissues and their types, with a focus on meristematic tissue and its role in plant growth. The presenter also shares an interesting fact about the fastest...

We've already learned a little bit about plant hormones, but let's dig a little deeper so that we can really examine the different ways that plants can respond to stimuli. These are called tropisms, and they can be positive or negative,...

This week Reactions dug our hands into some earthworm science. Some pretty useful chemistry comes out of these little critters in the form of compost. If you’re enjoying some tasty food today that has at least one ingredient that was...

We've gone over the various tiers of structure of a plant, from cells, to tissues, to organs and organ systems. Now it's time to better understand how plants grow. How to plants know when to grow? How do they know which direction to...

We've learned about the types of plant cells, and the types of plant tissues, so the next step up on the hierarchy of organization is organs and organ systems. Plants have these too! The stem, the leaves, the roots, these are all...
