The plasma membrane<\/p>\n\n\n\n
E.
The cell wall<\/p>\n\n\n\n
The Correct answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is E. The cell wall<\/strong>.<\/p>\n\n\n\n In plant cells, the cell wall plays a critical role in maintaining structural integrity, especially when the cells are exposed to hypotonic solutions. A hypotonic solution has a lower solute concentration compared to the inside of the plant cell. This difference in solute concentration causes water to move into the cell by osmosis. As water enters the plant cell, the internal pressure, known as turgor pressure, increases. This pressure is essential for maintaining the cell’s shape and firmness.<\/p>\n\n\n\n However, without a cell wall, the excess water would cause the plant cell to swell excessively and potentially burst due to the pressure exerted by the incoming water. The plant cell wall, composed mainly of cellulose, provides a rigid barrier that withstands this internal pressure. It is not only structurally supportive but also protective, allowing the cell to retain its shape and prevent lysis (bursting).<\/p>\n\n\n\n The cell wall acts like a safety valve. When the pressure inside the cell rises, the cell wall expands slightly but prevents the cell from bursting. This rigidity is particularly advantageous for plants, as it allows them to maintain turgor pressure, which is crucial for their growth, nutrient transport, and overall health. Additionally, turgor pressure supports the plant’s upright position, enabling it to capture sunlight effectively for photosynthesis.<\/p>\n\n\n\n In summary, while other structures within the plant cell, such as the plasma membrane and organelles like chloroplasts, contribute to cellular function, it is the cell wall that is primarily responsible for preventing the cell from bursting in hypotonic environments. This characteristic is essential for plants, allowing them to thrive in various water conditions without compromising their structural integrity.<\/p>\n","protected":false},"excerpt":{"rendered":" What prevents a plant cell from bursting in a hypotonic solution?
