Plant Groups



Plants: Presence of two main groups

Introduction

Although they all belong to the Plantae Kingdom, plants can be divided into groups and subgroups according to certain (specific) characteristics that differentiate each other. According to the visibility of the gamete producing structures, the plants can be divided into: cryptogams and phanerogams.

Cryptogama Plants

The name originates from the Greek, and crypto means hidden and gamae corresponds to gamete.

The main characteristic of these plants is the fact that they have little visible gamete production system.

Examples: ferns, fences, liverworts and mosses.

Cryptogram subgroups:

- Bryophytes: vegetables that do not have specialized vessels for conducting sap. They are small size plants.

- Pteridophytes: vegetables that have vessels for sap transport. They are large size plants. They are also called vascular plants.

Phanerogamous Plants

The name also has Greek origin, being that fanero means visible and gamae corresponds, as we saw earlier, to gametes.

Phanerogamous plants have their gamete-producing systems clearly visible. They are also known as spermatophytes because they produce seeds.

Examples: pines, crests, rose bushes, hoses, orange, lemon, apple and coconut.

Phanerogamous subgroups:

- Gymnosperms: are the vegetables that do not produce fruits, although they have seeds.

- Angiosperms: The seeds of these plants are allocated inside fruits. These fruits originate from the ovary development of the flowers.
