the anatomy of isobilateral and dorsiventral leaf is similar in many ways. however,it shows the following characteristic differences:
1. In monocot leaf the stomata are present on both the surfaces of epidermis
2. Mesophyll is not differentiated into palisade and spongy chlorenchyma
3. In upper epidermis of monocot leaf bulliform cells occur at regular interval which
helps in reducing the rate of transpiration
4. the vascular bundle of dicot leaf is covered with parenchymatous bundle sheath
and vascular bundle of monocot leaf are surrounded by sclerenchymatous and parenchymatous sheath.
A dicot leaf is usually dorsiventral having palisade on the upper side and spongy parenchyma on the lower side. Thus it has both dorsal and ventral sides.
Cassia leaf belongs to dicot family Caesalpiniaceae. It has reticulate venation and dorsiventral symmetry.
Nerium leaf is dicot. Dicot leaves have reticulate venation and dorsiventral symmetry.
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
Yes, there are stoma present. Rhoeo leaves have dorsiventral symetry. The dorsal side being pink in color have more stomata and ventral side facing sun is green with less stomata per unit area.
because lower epidermis is not covered with dust which falls from above.
Gourd belongs to family Cucurbitaceae. Hence it has dorsiventral leaf with reticulate venation.
The rigid side of the leaf is upper side facing the sunlight. In a dorsiventral leaf this side supports the palisade tissue.
Cassia leaf belongs to dicot family Caesalpiniaceae. It has reticulate venation and dorsiventral symmetry.
Nerium leaf is dicot. Dicot leaves have reticulate venation and dorsiventral symmetry.
Because monocot leaf does not have dorsiventral symmetry. It has mesophyll in the middle and epidermis on both sides inturrupted with stomata. since it is identical on both sides, it is called isobilateral.
Dicot leaf is also called dorsiventral leaf as it has both dorsal and ventral side with identifiable features. The protective layer is named as Epidermis and there is both upper and lower epidermis. In dorsiventral leafs the lower epidermis which is also called abaxial side will have more number of stomata compared to the adaxial side or upper epidermis. The gap between the two epidermis is termed as mesophyll and in dicot leaf we can see a differentiated mesophyll region. The region is differentiated into palisade and spongy tissue. The region just below upper epidermis have elongated parenchyma cells with chlorophyll filled in and they are called Palisade tissues. This is the main reason behind dark green colour at upper side of a dicot leaf.
The upper surface of a hibiscus leaf generally has fewer stomata than the lower surface. The lower surface tends to have a higher density of stomata to facilitate efficient gas exchange through transpiration. The specific number of stomata can vary depending on the age and health of the leaf, as well as environmental conditions.
A typical dorsiventral leaf has a petiole, leaf blade, mid rib and large number of veins. The leaf blade can be differentiated into palisade and spongy parenchyma. Both these tissues are surrounded by an epidermis which is interspersed by stomatal pores. The mid rib and its associated veins are provided with vascular bundles.
The layer of a leaf where most food-making occurs is the palisade mesophyll. This layer contains chloroplasts that are responsible for photosynthesis, converting sunlight into energy for the plant. The palisade mesophyll is located just beneath the upper epidermis of the leaf.
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
Yes, there are stoma present. Rhoeo leaves have dorsiventral symetry. The dorsal side being pink in color have more stomata and ventral side facing sun is green with less stomata per unit area.
The upper epidermis is responsible for preventing water loss by evaporation. It does this by having a waxy cuticle on the top of the leaf. The lower epidermis has stomata, which allow gases to enter and leave the leaf as a result of photosynthesis and respiration.
