Question

In a turgid cell, value of which of the following is zero?

• A. suction pressure $(SP)$
• B. wall pressure $(WP)$
• C. turgor pressure $(TP)$
• D. osmotic pressure $(OP)$

Answer 1

Answer: (A)

suction pressure $(SP)$

Answer 2

In a turgid cell, turgor pressure $(TP)$ is equal to $WP$ (wall pressure) so suction pressure or $DPD$ becomes zero i.e., no more water can come inside. It can be shown by the following equation $DPD (SP) - TP - WP$ $\because TP - WP$ (in turgid cells) $\therefore DPD$ or $SP - 0$
