why does coconut fruit have thick fibrous coat
Answers
Explanation:
Coconut is a simple fleshy fruit of which pericarp is differentiated into three layers as epicarp, mesocarp and endocarp.
Hydrochory requires seed or fruits to develop floating devices in the form of fibrous coats and waterproof coats.
Coconut epicarp is thick and waterproof.
Both fibrous mesocarp and stony endocarp of coconut renders the coconut to float in water. Such fibrous fruits can float for long distances. Therefore, coconut is dispersed by hydrochory.
Therefore, the correct answer is option D.
Answer:
An untouched coconut has three layers. The outermost layer, which is typically smooth with a greenish color, is called the exocarp. The next layer is the fibrous husk, or mesocarp, which ultimately surrounds the hard woody layer called the endocarp. The endocarp surrounds the seed.In coconut brown covering (thin layer) adherent to the kernel around the endosperm is seed coat. A seed coat protects the internal parts of the seed from fungi, bacteria and insects and prevents water loss. The seed coat must split open before a new plant may emerge.
