What is an Isobilateral leaf?
What is an Isobilateral leaf?
In the case of isobilateral leaf, the mesophyll tissue in the leaves is not differentiated. It is made up of either only spongy or palisade parenchyma cells. These type of leaves are similar in appearance on both the sides and hence, are called as isobilateral type of leaves.
Which is normally found in Isobilateral leaf?
Solution : In isobilateral leaf palisade is present on both sides of the leaf and inbetween them spongy perenchyma is present. Example Nerium.
Is Isobilateral leaf a monocot leaf?
– Bulliform cells are present. Examples of the Isobilateral leaf are- monocots such as maize, lilies, irises, amaryllises etc. Note: Isobilateral leaves orient themselves as parallel to the main axis as well as parallel to the direction of sunlight.
Why is the monocot leaf is Isobilateral?
Monocot leaves are called isobilateral leaves since both the sides of monocot leaves are more or less similar.
What is the difference between Isobilateral and dorsiventral leaf?

| Dorsiventral Leaf | Isobilateral Leaf |
|---|---|
| The number of stomata is more on the abaxial epidermis than the adaxial epidermis. | Almost equal number of stomata is present on the abaxial and adaxial surfaces. |
What do Isobilateral leaves lack?
It shows the following characteristic differences. In an isobilateral leaf, the stomata are present on both the surfaces of the epidermis; and the mesophyll is not differentiated into palisade and spongy parenchyma (Figure).
What is the difference between Isobilateral leaf and dorsiventral leaf?
Which of the following is incorrect about Isobilateral leaf?
Leaf, in which both surfaces are similar in appearance are called isobilateral leaves. These are found in monocotyledons. It is due to the presence of spongy parenchyma. So, the correct option is ‘Similarly two green surfaces’.
Which is not Isobilateral leaf?
Rice, wheat and, sugarcane all are monocots. So, they have an isobilateral leaf. Mango being a dicot has a dorsiventral leaf.
Which of the following is not an Isobilateral leaf?
What is Dorsoventral leaf?
A dorsiventral (Lat. dorsum, “the back”, venter, “the belly”) organ is one that has two surfaces differing from each other in appearance and structure, as an ordinary leaf. This term has also been used as a synonym for dorsoventral organs, those that extend from a dorsal to a ventral surface.
Do Isobilateral leaves have cuticle?
The Cuticle is present on the outer wall stomata are present on both upper and lower epidermis. Mesophyll: it’s the bottom tissue that’s present between both epidermal layers. These cells contain chloroplasts. The Mesophyll isn’t differentiated into palisade and spongy parenchyma.
What are the features of dorsiventral leaf?
In dorsiventral leaf, it is differentiated into pallisade parenchyma and spongy parenchyma. Palisade parenchyma lies towards the upper epidermis and consists of one, two or three layers of elongated cells, densely packed with profuse intercellular spaces and chloroplasts.
Which of the following characteristics are related to Isobilateral leaf?
| Dorsiventral Leaf | Isobilateral Leaf |
|---|---|
| Vascular bundles are large and vary in size as per the size of veins. | Vascular bundles are similar in size, only the bundles near the mid vein are large. |
| Bulliform cells are absent. | Bulliform cells are present. |
Which of the following characters are related to Isobilateral leaf?
| Question | Which of the following characters is/are related to isobilateral leaf? ( a ) Stomata are present on both surfaces. ( b ) Mesophyll is differentiated into palisade and spongy parenchyma. ( c ) Sub-stomatal cavity is present below the stoma of the abaxial epidermis. |

How is dorsiventral leaf different from an Isobilateral leaf?
What is the difference between dorsiventral leaf and Isobilateral leaf?
What is bifacial leaf?
A dicotyledonous leaf is also called dorsiventral or bifacial leaf. For example, mango leaves, banyan leaves and oleander leaves. These leaves are hypostomatic (stomata mostly on the lower epidermis). Mesophyll tissues present in these leaves are differentiated into palisade and spongy.
Which of the following is incorrect about Isobilateral?
What is Unifacial leaf?
Unifacial leaf is a leaf that develops from one side of the leaf primordium only and in consequence has only an encircling adaxial or abaxial epidermis (may be secondarily flattened and appear dorsiventral).
What is an isobilateral leaf?
Isobilateral: Isobilateral leaves are found in monocotyledonous plants. Such leaves generally remain vertical. These are called the isobilateral leaves as both surfaces (upper and lower) are equally green and similar to one another.
What is the internal structure of leaf?
A leaf is a flattened appendage on the stem which is born in the node. The internal structure of the leaf tells us about the arrangement of the different cells or tissues. Typically the internal structure of leaves comprises the upper epidermis and lower epidermis encompassing the mesophyll cell.
What is the structure of dorsiventral leaf?
A typical dorsiventral leaf e.g., mango, in transverse section, shows the following structures: It is formed of a single layer of cells, which are closely fitted and have outer thick walls. The outer wall is usually cutinized.
What determines the size of the vascular bundles in dicotyledonous leaves?
The dicotyledonous leaves possess reticulate venation in which the veins form a network. The veins vary in thickness in the reticulate venation. Vein size determines the size of the vascular bundles. Hence, vascular bundles are larger in the thicker veins and smaller in the thinner veins.
