Question

what is dosoventral and isobilateral leaf ?

Answer 1

DORSRIVENTAL LEAVES

leaf type, found mainly in DICOTYLEDONS, with a structure that changes from dorsal (upper) surface to ventral (lower) surface. The major areas are: an upper EPIDERMIS with no stomata; a palisade MESOPHYLL layer below which is spongy mesophyll with large intercellular spaces; a lower epidermis with irregularly spaced STOMATA. Such leaves are generally held horizontally.

Isobilateral (monocotyledonous) leaf

Isobilateral leaves orient themselves parallel to the main axis and parallel to the direction of sunlight. Most monocots possess parallel-veined isobilateral leaves, including grasses and grasslike plants, lilies, irises, amaryllises etc.
