Cells are like living bricks. They come in all different shapes and sizes, and they have different functions. But when cells work together, they can form tissues.

Living things have many requirements. One of the most important of these is that they must obtain food. They get this food from the environment. The ultimate source of food energy is the sun. The sun produces light, and this light is used by plants in a process called photosynthesis. Photosynthesis converts some of the […]
Living things interact with their environments in order to thrive and live. Some of the things they interact with are biotic, while some are abiotic. Biotic and abiotic are just big science words that mean living and non-living. Biotic factors are living organisms that affect an ecosystem. They can be plants, animals, or other organisms. […]

Cells are the basic unit of all living things, from single cells that compose the simplest organisms to trillions of cells in the human body’s intricate structures. Every living entity on Earth is composed of cells. We call this the cell theory. According to the cell theory, cells are the fundamental building blocks of living […]
It is often stated that dogs are man’s best friend. Why do you think this is the case? Why do two species which are so different from one another, get along so well. The answer lies in something called artificial selection. What is artificial selection? Artificial selection, or selective breeding as it is often called, […]
Living things are divided into six kingdoms of life based on how they are alike and how they are different. The largest of these kingdoms is the animal kingdom. Animals come in many different shapes and sizes. Some have exoskeletons, while others have no skeletons at all, and still others have highly evolved internal skeletons. […]
Pandas are large animals with famously black-and-white fur. Such vivid coloring in the wild might seem like an invitation for predators such as leopards, or tigers to see and attack them. Surprisingly, researchers have found that the coloration which does not seem to be very effective at camouflaging them still offers them protection. “In its […]
