Meristematic tissue cells do not contain large vacuoles because they remain actively involved in continuous cell division. These cells require dense cytoplasm and sufficient space for rapid metabolic activities. Vacuoles mainly store materials and occupy large space, which could slow cell division.Read more
Meristematic tissue cells do not contain large vacuoles because they remain actively involved in continuous cell division. These cells require dense cytoplasm and sufficient space for rapid metabolic activities. Vacuoles mainly store materials and occupy large space, which could slow cell division. Therefore, absence of vacuoles helps meristematic cells divide quickly and efficiently for plant growth and development.

When soaked mung bean seeds are placed in a concentrated solution, water moves out of the cells due to osmosis. The surrounding solution has higher solute concentration, causing water loss from seeds. This leads to shrinking of cells and reduction in size. The seeds become flaccid and lose their swoRead more
