HORTICULTURE

Detailed explanation-1: -Lower surfaces are not directly exposed to sun. This tends to reduce excessive water loss. It is a beneficial adaptation to check water loss in plants. Thus, the underside of leaves have more stomata.

Detailed explanation-2: -Stomata are more numerous on the lower side of the leaf to prevent transpiration. Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

Detailed explanation-3: -In most cases, the lower epidermis contains more stomata than the upper epidermis because the bottom of the leaf is cooler and less prone to water loss.

Detailed explanation-4: -The more number of stomata present at the lower surface of the dicot leaves than the upper surface of the leaves to prevent excess water loss.

Detailed explanation-5: -Hypostomatous leaves are those that have stomata solely on the lower side. Dicot leaves are able to preserve water thanks to their stomatal configuration. More stomata are present on the surfaces of plants, which thrive in conditions of increased light, decreased atmospheric carbon dioxide concentrations, and moisture.
