Question:

Spongy tissue is generally situated towards which side in dorsiventral leaf?

Options:

1. Abaxial
2. Adaxial
3. Upper
4. Ventral

Solution:

Spongy tissue is a type of parenchyma tissue in the leaf that is involved in gas exchange and is located towards the abaxial (lower) side of a dorsiventral leaf. Dorsiventral leaves, also known as bifacial leaves, have distinct upper (adaxial) and lower (abaxial) surfaces with different anatomical features. The spongy tissue is located in the lower part of the leaf, towards the abaxial surface, and is characterized by loosely arranged parenchyma cells with abundant air spaces, allowing for efficient gas exchange between the leaf and the external environment. Option 1, which mentions abaxial, is the correct answer. Options 2, 3, and 4 are not correct as they do not accurately describe the position of spongy tissue in a dorsiventral leaf.
