Question

In acacia species, the first few leaves are pinnately compound then there are leaves with flattened petiole and fewer pinnae. The leaves of the adult plant have parallel-veined flattened petiole and no pinnae. It shows that
A. Leaves of the adult plant are reduced to phyllodes while those of the seeding is unreduced
B. The parallel-veined green structure of the adult plant is phylloclades
C. The plant shows development heterophylla compound in seeding and simple in adult plant
D. The leaves of the adult plant are unreduced while they are reduced in the seedling stage

Answer 1

Hint:- In quite a several species, of basically Australian Acacia, the petiole and part of rachis expand to shape phyllode, which essentially in all fairness is great. Phyllodes form are genuinely vertical in particular have fewer stomata and therefore, for the maximum part lose type of less water in transpiration, which sort of within reason is massive.

Complete Answer:- In Acacia species, the primary for all intents and functions few specifically leaves in most cases are pinnately compound in a truly primary manner. Then there generally are true leaves with flattened petiole and much fewer pinnae, or so they honestly thought. The without a doubt leaves of grownup plants ordinarily have surely parallel-veined flattened petiole and no pinnae, demonstrating that during Acacia species, the primary certainly few leaves are pinnately compound, which simply is quite huge. It indicates that generally leaves of the adult plant, on the whole, are decreased to phyllodes at the same time as those of the seedling stage typically are unreduced, definitely similarly displaying how it suggests that leaves of the adult plant specifically are decreased to phyllodes whilst those of the seedling stage, for the most part, are unreduced in a diffused way. The truly parallel-veined flattened petiole in-person plant life essentially is referred to as phyllodes in a subtle way.
In acacia species, the primary few leaves are pinnately compound then there are leaves with flattened petiole and fewer pinnae. The leaves of the person plant have parallel-veined flattened petiole and no pinnae. It indicates that Leaves of man or woman plants are decreased to phyllodes whilst the ones of the seeding are unreduced.

Hence, the correct answer is option A.

Note:- Acacia, generally known as the wattles or acacias, essentially is a fairly large genus of shrubs and trees inside the subfamily Mimosoideae of the pea's own family Fabaceae. It contains a collection of plant Genera type of local to Africa and Australasia, in reality, opposite to famous perception. Acacia especially stays an extensively used certainly commonplace name throughout Genera, so acacia for the most element stays a broadly used sort of commonplace name throughout Genera, or so they without a doubt concept.
