网页2014年12月5日 · For example, Rauh's model describes trees with a monopodial trunk, whorled orthotropic branches that are identical to the trunk and lateral flowering (in angiosperms).
12.2: Secondary Growth - Biology LibreTexts
网页2023年7月14日 · One way to determine whether you are looking at an angiosperm or gymnosperm cross section is to look for the presence of large, open cells in the xylem (vessel elements). Gymnosperms (excepting the gnetophytes) only have tracheids, whereas angiosperms have both tracheids and vessel elements.

网页2022年7月31日 · True woody tissue is rarely found in monocots. In palm trees, vascular and parenchyma tissues produced by the primary and secondary thickening meristems form the trunk. The pollen from the first angiosperms was monosulcate, containing a single furrow or pore through the outer layer. This feature is still seen in the modern monocots.
