What does the term "dicotyledon" signify about a tree?

It sprouts only one seed leaf
It has three seed leaves
It produces flowers in clusters
It has two seed leaves at germination

The correct answer is: It has two seed leaves at germination

A tree being dicotyledonous means that it has two seed leaves when it first germinates. This is significant because it is a defining characteristic of dicot trees, which make up a large portion of the world's trees. Option A is incorrect because monocot trees, which also make up a significant portion of trees, only sprout one seed leaf. Option B is incorrect because most trees actually only have two seed leaves, not three. Option C is incorrect because flower production is not related to the number of seed leaves a tree has.
