In plant cells, which organelle primarily stores water and other dissolved substances (cell sap) to help maintain turgor pressure and support cell structure?
A
Mitochondrion
B
Central vacuole
C
Chloroplast
D
Golgi apparatus
Verified step by step guidance1
Identify the organelles listed in the problem and recall their primary functions in plant cells.
Understand that the mitochondrion is mainly responsible for energy production through cellular respiration, not storage of water or cell sap.
Recall that chloroplasts are involved in photosynthesis, converting light energy into chemical energy, and do not primarily store water or dissolved substances.
Recognize that the Golgi apparatus functions in modifying, sorting, and packaging proteins and lipids, rather than storing water or maintaining turgor pressure.
Conclude that the central vacuole is the organelle that stores water and dissolved substances (cell sap), which helps maintain turgor pressure and supports the cell structure in plant cells.
