FAQs on Anatomy of Dicot Leaf Video Lecture - Biology for ACT
| 1. What is the anatomy of a dicot leaf? |  |
Ans. The anatomy of a dicot leaf consists of several layers. The uppermost layer is the cuticle, which is a waxy coating that helps prevent water loss. Below the cuticle is the upper epidermis, which contains stomata for gas exchange. The mesophyll layer is sandwiched between the upper and lower epidermis and is made up of the palisade mesophyll and spongy mesophyll. The palisade mesophyll contains chloroplasts for photosynthesis, while the spongy mesophyll allows for gas exchange. The lower epidermis also contains stomata, and the leaf is supported by vascular bundles.
| 2. What is the role of stomata in a dicot leaf? | |
Ans. Stomata are small openings found on the surface of a dicot leaf. Their main role is to regulate gas exchange, allowing for the uptake of carbon dioxide for photosynthesis and the release of oxygen. Stomata also play a crucial role in controlling water loss through transpiration. They can open and close to regulate the amount of water vapor that escapes from the leaf. This helps maintain the plant's water balance and prevents excessive water loss in dry conditions.
| 3. What is the function of the mesophyll layer in a dicot leaf? | |
Ans. The mesophyll layer in a dicot leaf is responsible for photosynthesis. It is composed of two types of cells: the palisade mesophyll and the spongy mesophyll. The palisade mesophyll cells are located near the upper epidermis and contain a high concentration of chloroplasts. These chloroplasts capture sunlight and carry out photosynthesis, converting carbon dioxide and water into glucose and oxygen. The spongy mesophyll, located below the palisade layer, allows for gas exchange and the movement of nutrients throughout the leaf.
| 4. What is the cuticle and why is it important in a dicot leaf? | |
Ans. The cuticle is a waxy layer that covers the upper epidermis of a dicot leaf. It serves as a protective barrier, preventing excessive water loss from the leaf's surface. The cuticle helps to reduce evaporation by providing a waterproof coating that limits the diffusion of water vapor. This adaptation is especially important in dry environments or during periods of drought, as it helps the plant conserve water and maintain proper hydration. Additionally, the cuticle can also protect the leaf from harmful pathogens and UV radiation.
| 5. How do vascular bundles support a dicot leaf? | |
Ans. Vascular bundles in a dicot leaf provide support by transporting water, nutrients, and sugars throughout the leaf. They are composed of xylem and phloem tissues. Xylem tissue transports water and minerals from the roots to the leaf, while phloem tissue transports sugars produced during photosynthesis from the leaf to other parts of the plant for energy storage or growth. The vascular bundles form a network of interconnected vessels, providing structural support to the leaf and ensuring the efficient distribution of essential substances.
