We now have a plant that can obtain carbon, water, and nutrients. Before we can discuss growth, we need to understand the tissue types and their function. Vessel elements are most important in angiosperms 2.
Roots grow continuously at the tips.
Formed by the apical meristem and the cells right behind it. If they were in the zone of elongation they d be ripped off o They are produced and die off at about the same rate These cells are no longer increasing in size but are going through differentiation 3. In monocots, the primary root dies back quickly, and adventitious roots grow from the stem. These produce fibrous roots all similar in size. Primary growth in shoots As we just saw, roots are fairly simple structures which grow only at their tips.
