1. STEMS  TYPES OF STEMS 1-Herbaceous- Annual plants -Vivacious plant 2-Ligneous-Trees –Shrubs - Bushes 3-Under ground-Rhizomes –Tubers- Bulbs 4-Succulent stem

2. They do not have developed ligneous stiffened structures they are generally frail Herbaceous Ligneous They have developed rigid stiffened structures.

3. Plants with ligneous stems,with a superior height of five meters. Trees Shrubs Are those plants with ligneous stems,from one to five tall.in this case,branching begins at soil level

4. Bushes Ligneous plant shorter than one meter tall. Succulent stem They become very fat because of water accumulation.

5. plant with a year lifetime.weeds generally belong to this group. Annual plants Vivacious plant Plant with aerial stems lasting a single season,but keeping underground structures form which new stems spring again next season.
