概括
这项研究表明,果果,而不是卵泡,很可能是ANA等级的芽植物和所有开花植物的祖先水果类型. 这表明果在血管精子历史的早期发展.
科学领域:
- 植物学 植物学
- 进化生物学 进化生物学
- 古植物学是古植物学.
背景情况:
- 亚纳等级的生苗表现出多样化的形态,但共享推断的plesiomorphic特征,如apocarpous gynoecia和特定的游戏细胞结构.
- 奥斯特罗贝莱亚尔斯的肉类学仍未得到充分的研究,因此需要对血管苗类的祖先果实和种子类型进行研究.
研究的目的:
- 为了描述ANA等级的种类的肉类学特征,专注于奥斯特罗巴伊莱雅斯.
- 通过分析水果结构来研究血管苗的祖先水果和种类.
主要方法:
- 光显微镜被用来研究骨和种子外的解剖学.
- 使用WinClada软件进行了字符优化.
主要成果:
- 奥斯特罗贝莱亚,特里梅尼亚,卡德苏拉和斯基桑德拉的果实被确定为斯基桑德拉类型的apocarpous果.
- 推断的情景表明,阿波卡尔普斯果是血管精子的多形果类型,表明早期果的进化.
- Plesiomorphic 种子类型要么缺乏一个 sclerenchymatous 层,要么是 exotestal.
结论:
- 作为ANA等级的种群和整体的血管精子的可能的形特征,建议使用apocarpous果,而不是毛囊.
- 这一发现支持果的早期进化起源在苗中.

The Angiosperm Life Cycle
65.3K
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.

Fruit Development, Structure, and Function
22.3K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

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
28.3K
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.
