BOT 1010L Lecture Notes - Lecture 13: Fruit Anatomy, Meristem, Monocotyledon
Document Summary
3 layers: exocarp (outer layer), mesh carp and endocarp). Woody plants has lateral meristem causing plant to frown in thickness and strength. This secondary growth is characteristic of woody trees, shrubs, and vines. Herbaceous plants lack secondary growth and tend to die back in the winter. Deciduous plants lose their leaves or needles in winter. The plants lose and replace some leaves or needles every year. Monocots (monocotyledons) leaves are narrow and parallel veined, flower parts are in threes, stems have vascular bundles scattered throughout, there is generally no secondary (woody) growth, one leaf emerges from seed. Dicots (dicotyledon) leaves are wide and net veined, flower parts are not usually in multiples of three, vascular bundles in the stem are arranged in a ring, there may be secondary growth, two leaves emerge from seed. In the first year they produce leaves, roots, and compact stems. Flowers are produced and seeds developed in the second year.
