Question

1. Stomata open due to​

Answer 1

Answer:

Stomata are open during the day because this is when photosynthesis typically occurs. Opening and closing of stomata occur due to turgor changes in guard cells. When guard cells are turgid, stomatal pores is open … Stomata take in C02 required for the photosynthetic activity during the day.

ExplanationStomata are composed of two guard cells. These cells have walls that are thicker on the inner side than on the outer side. This unequal thickening of the paired guard cells causes the stomata to open when they take up water and close when they lose water.

Answer 2

Stomata open and close due to turgor pressure of guard cells. When turgid, they swell and bend outward. As a result, the stomatal aperature opens. When they are flaccid, the tension from the wall is released and the stomatal aperture closes.
