There are many different types of cells in animals. Each type is specialised ... They therefore support the plant. Dissolved sugars and amino acids can be transported both up and down the stem.

Experiments with mutant plants and selective cell killing have shown that plant stem cells are maintained by signals from other, adjacent, cells. This feature is shared with animal stem cells and ...

The way we study plant cells is expanding—literally—thanks to new research from Kevin Cox, an assistant professor of biology ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...
