This balance can be upset when the cell wall is damaged, causing the highly pressured vacuole to rupture and release its contents, which can lead to cell death. While the mechanisms that ensure ...

and the lytic vacuoles of acidic pH, which are equivalent in function to lysosomes in mammalian cells (Figure 1). A special feature of guard cells is that they can increase or decrease their ...

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 ...

As a grad student in cell biology, Shaeri Mukherjee was always on the lookout for new ways to fiddle with cells’ internal structures. It was the early 2000s, and Mukherjee was working in Dennis ...

Cells are made up of different parts. Vacuole Contains a liquid called cell sap, which keeps the cell firm Plant cells only Cell wall Made of a tough substance called cellulose, which supports and ...

Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Plants feel firm because of their cellular walls.
