why more stomata appears in dicot than monocot ?
Monocot and dicot plants are two different types of flowering plants. Monocots have one cotyledon (seed leaf) while dicots have two. Other differences include the arrangement of vascular tissue, root system, and flower structure.
Stomatal density refers to the number of stomata (pores) present on the surface of plant leaves. Stomata are responsible for gas exchange, allowing plants to take in carbon dioxide and release oxygen.
Generally, monocots have a higher stomatal density compared to dicots. This is because monocot leaves are typically longer and have a higher surface area, requiring more stomata for gas exchange.
Stomatal density plays an important role in regulating the exchange of gases, such as carbon dioxide and oxygen, in plants. It also helps plants to control water loss through transpiration.
Stomatal density can be influenced by various factors, including environmental conditions (such as light, temperature, and humidity), genetics, and plant age. It can also be altered by certain plant hormones and growth regulators.
