Answer 1

The trees can grow as high as 25m and the seeds weigh around 20 kg each. The fruit of this palm is even referred to as double coconut or sea coconut. The fruit itself is 40 to 50 cm long and can even contain 2-3 seeds at once. The largest and heaviest seed is found in a type of palm tree that is native to Seychelles.

Complete answer:
The largest and heaviest seed is that of Lodoicea. Lodoicea maldivica is a type of palm tree that is native to Seychelles. Even though it grows slowly, it can reach up to 25m in height. This tree produces seeds that can weigh up to 20 kg and are almost 40 cm in diameter. This makes them the largest and heaviest seeds in the world. The seeds take seven years to mature completely.

The seed in its immature form contains a translucent jelly-like substance that is eaten as a dessert. It was believed that the seeds were dispersed by water, however, since they are so dense, it was concluded that they fall off and germinate under the tree itself. That is why this species of palm is endemic to certain areas.

Hence, the correct answer is option (A).

Note: Lodoicea maldivica has various uses, such as:
The endosperm of the fruits can be consumed. The terminal bud is considered to be a vegetable and is even preserved in vinegar. The endocarps of the fruits are repurposed in the form of plates, bowls, and other vessels. Since the leaves are quite wide and fanny, they have various uses. They can be used to make baskets, hats, and even thatching material.
