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...

How Diatoms Build Their Beautiful Shells

Sugars move up and down the plant in the phloem. The phloem uses active transport to transport the food nutrients like glucose and amino acids around the plant. Glucose is made in the leaves by photosynthesis. Glucose is converted into...

It’s fun to watch organisms eat in the microcosmos. There’s a whole range of methods to enjoy. And at the core of all this is a simple, universal need: energy, stored chemically as adenosine triphosphate—or ATP—that’s made from the...
