Unlocking the Wonders of Seed Bearing Plants: A Comprehensive Guide

Seed bearing plants, also known as spermatophytes, are an integral part of our planet's biodiversity and human civilization. These incredible organisms have revolutionized the way we sustain ourselves, adorn our surroundings, and explore the world of botany. In this comprehensive guide, we delve into the fascinating world of seed bearing plants, offering you valuable insights to enhance your understanding and appreciation.

Anatomy of Seed Bearing Plants

Seed bearing plants are characterized by their ability to produce seeds, which contain the embryo of a new plant. They possess a complex vascular system that transports water and nutrients throughout their structures. These plants typically have true roots, stems, and leaves.

Structure	Description
Seed	Contains the embryo, food supply, and protective coat
Embryo	The young plant within the seed
Cotyledons	The first leaves of the seedling
Radicle	The embryonic root
Plumule	The embryonic shoot

Types of Seed Bearing Plants

Seed bearing plants are divided into two main groups:

Group	Description
Gymnosperms	Seeds are not enclosed in an ovary
Angiosperms	Seeds are enclosed in an ovary
