Ch 9 Seed Plants. Pp. 274-300. Notes 9-1. All seed plants share 2 characteristics. They have vascular tissue and use seeds to reproduce. They all have body plans that include leaves, stems, and roots. Water, food, and nutrients are transported throughout the plant’s vascular tissue.By emmly
Kingdom Plantae. General Characteristics:. Eukaryotes Multicellular; organized into tissues, organs and systems Cell walls present (cellulose) Autotrophs ; contain chloroplasts Reproduce sexually. General Characteristics. What Plants need: Sunlight to carry out photosynthesisBy rupert
Vascular Plants with Seeds. These plants do not require water for sexual reproduction. They reproduce by seeds rather than spores. Seeds are multicellular and contain a young plant called an embryo. Characteristics of Seed Plants.By isha

第 9 章 裸子植物 (Gymnosperm). 种子植物的主要特征 1. 产生种子，胚由种皮包被得到保护 2. 形成花粉管，受精作用离开水 3. 有明显的世代交替， 孢子体高度发达， 配子体进一步退化， 配子体寄生在孢子体上。. 分类 裸子植物门：胚珠落露，不形成果实 有颈卵器，无精子器 被子植物门：胚珠由心皮包被，形成果实
O vule eggs (n) will form inside the female gametophyte within the megaspore (n) formed by the megasporocyte (2n). Plant group: Gymnosperm Phylum Coniferophyta , Structure: pine ovulate cone.
