Detailed Solution

Angiosperms are flowering plants with distinct features. The tallest angiosperm is the Eucalyptus (Eucalyptus regnans).

About Eucalyptus – The Tallest Angiosperm

Eucalyptus is not only the tallest angiosperm but also among the tallest trees in the world.
These trees are fast growers, reaching heights of 30 to 180 feet or more, depending on the variety.
While eucalyptus oil and extracts are used in small amounts in food and medicine, excessive consumption can be toxic.
Symptoms of eucalyptus poisoning may include: stomach pain, dizziness, muscle weakness, constricted pupils, difficulty breathing, and burning sensations.

Salient Features of Angiosperms

The embryo sac (ovule) remains enclosed within the ovary.
Flowers, not cones, are produced.
Double fertilization occurs, resulting in a triploid endosperm.
Fertilization does not require water.
Angiosperms are divided into monocotyledons and dicotyledons, based on the number of cotyledons in the seed.
The endosperm provides nutrients to the embryo.
They exhibit seed, flower, and fruit formation.
