Question

Why is phloem parenchyma absent in most monocots, and do they have alternative structures for storing food material?

a. Monocots lack storage structures for food material.
b. Monocots possess alternative structures for storing food material.
c. Phloem parenchyma is unnecessary in monocots for food storage.
d. The absence of phloem parenchyma does not impact food storage in monocots.

Answer 1

Phloem parenchyma is absent in most monocots, and they have alternative structures for storing food material.

Step-by-step explanation:

In most monocots, phloem parenchyma is absent. Monocots have alternative structures for storing food material. The food reserves in monocots are stored in the endosperm, which is a tissue present in the seed. This endosperm contains the stored carbohydrates, proteins, and lipids, which are degraded by enzymes secreted by the aleurone layer. The absorbed products are then transported to the developing embryo through the scutellum, which acts as an absorptive organ.
