Resumen

Los fósiles recién descubiertos del Cretácico Temprano revelan cúpulas recurrentes comparables al segundo integumento de los óvulos de las angiospermas. Este hallazgo ofrece información sobre el origen de las angiospermas (plantas con flores) y la evolución del carpelo.

Área de la Ciencia:

La paleobotánica
Biología evolutiva
Genética del desarrollo

Sus antecedentes:

El único segundo integumento de los óvulos de angiospermas los distingue de otras plantas de semilla.
Comparar esta estructura con las plantas de semilla extintas es clave para comprender los orígenes de las angiospermas.
Las interpretaciones anteriores estaban limitadas por la evidencia fósil insuficiente.

The Angiosperm Life Cycle

The Angiosperm Life Cycle

Plants have a life cycle split between two multicellular stages: a haploid stage—with cells containing one set of chromosomes—and a diploid stage—with cells containing two sets of chromosomes. The haploid stage is the gamete-producing gametophyte, and the diploid stage is the spore-producing sporophyte.

Introduction to Seed Plants

Introduction to Seed Plants

Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms.

Seed Structure and Early Development of the Sporophyte

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.
