Gymnosperms, therefore, as exemplified by pine trees, are heterosporous. A major distinction we can make between seed plants (gymnosperms and angiosperms) and the non-seed plants (mosses and ferns) is that seed plants are heterosporous and non-seed plants are homosporous.

Angiosperms vs. Gymnosperms. Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones.

Angiosperms are unique plants because they produce protected seeds. This alternation of generations in flowering plants, such as oak trees and wildflowers, means that there are multicellular stages that are haploid and diploid.

All land plants share the following characteristics: alternation of generations, with the haploid plant called a gametophyte, and the diploid plant called a sporophyte; protection of the embryo, formation of haploid spores in a sporangium, formation of gametes in a gametangium, and an apical meristem.

Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.

Some common characteristics that all plants share are they all have multicellular cells. All plants have a cuticle to protect the plant. Every plant has a root system that gets water and nutrients out of the soil and it also anchors the plant into the ground.

Like angiosperms, gymnosperms also have vessels and companion cells. The vascular system is common for the both of them, consisting of conjoint and vascular bundles (open and collateral). The ovules of both angiosperms and gymnosperms develop into seeds. Their mode of seed germination is epigeal, hypogeal, or both.

Gnetophyta's unique fertilization feature is that a tube grows from the eggs to unite with the pollen tubes in order for fertilization to take place between the gametophytes. ... This is the only type of gymnosperm that undergoes double fertilization, however no endosperm forms and the 2nd egg fertilized disintegrates.
