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 ...

One of the most fundamental differences between animal and plant cells is the cell wall—a rigid structure surrounding the plant cells. The cell wall provides strength and structural support, but it ...

Plant stem cells, as in animals, are maintained in specialized microenvironments, which are known as stem cell niches, where local signals from organizer cells act to prevent stem cell differentiation ...
