What makes avocado seeds so much bigger than other seeds?

Answer 1

Different plants have developed different strategies for reproduction. One strategy involves seed dispersion. Plants can't move so their seeds have to travel on their own. Some are very small or have wings or fluff and so can travel on the wind. Others are encased in tasty fruits and are eaten by animals and spread around in the droppings. Avocados appear to be in this category. I have heard that the fruit of the avocado has a taste and smell that is attractive to jungle predators such as jaguars. The seed is tough to resist digestion. Its smoothness lets it pass through the animal's gut even though it is large. Most seeds have a food supply for the sprouting plant (rather like the yoke of and egg.) The avocado seed has very large food supply. This may give the new plant an advantage getting started in the often poor tropical soils. Note that people often sprout these seeds by suspending them in a glass of water rather than in a pot of fertile soil.

Answer 2

Are they bigger than coconuts? No. OK where does an Avocado naturally grow and why does it need so much more food to survive at the start. If it is a place that forces them to get hieght before they can produce for themselves you might have an answer there.

Answer 3

Mechanism of dispersal--they were actually eaten by very large herbivorous and now extinct mammals. Then they passed through the digestive tract of these large mammals and were deposited.
Unfortunately, with the extinction of their primary dispersers, we may see eventual extinction of the avocado.
