Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders ...

A look at the cells of different organisms and a comparison of the structures found in plant and animal cells. All animal cells are surrounded by a membrane which contains the cytoplasm. Nearly ...

Epithelial tissues are layers of tightly connected cells and make up the basic structure of many organs. To create functional organs, tissues change their shape in three dimensions.

Animal and plant cells have different energy-producing structures inside them. For animals, that’s mitochondria , which convert chemical energy from food into a form that our cells can use.

It was previously thought that combining chloroplasts (chlorophyll containing structures in the cells of plants and algae) with animal cells was not possible, ...

In the past, combing chloroplasts—structures common in the cells of plants and algae that produce energy from sunlight—with ...

A first-of-its-kind achievement has implanted photosynthesizing cells in animal cells to make “planimals.” This feat could be the first step in crafting lab-grown meat, material for skin ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...
