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 ...

Plant cells without walls, known as protoplasts, are very fragile, and it has been difficult to keep them alive under a ...

Mitochondria close mitochondriaTiny parts of cells floating in the cytoplasm where energy is released from glucose. The glucose comes from food. This is how you make a model plant cell.

The cells that make up the walls of the finest of all lymphatic vessels have a lobate, oak leaf-like shape that makes them particularly resilient to changes in fluid volume. A similar cell shape also ...

Plant hormones, also known as phytohormones, are chemicals that regulate plant cell processes. They are signal molecules produced within the plant functioning in extremely low concentrations.
