Question

1. what is the purpose of bud scales? 2. describe the process by which stems grow in length. 3. why do not all buds grow? what determines which buds grow and which do not? 4. what are two branching patterns?

Explanation:

1. Bud scales protect buds from environmental stresses like cold and desiccation.
2. Stem growth in length occurs through cell - division and elongation in the apical meristem.
3. Bud growth is determined by factors such as hormonal balance and environmental cues; not all buds grow due to apical dominance or lack of resources.
4. Two branching patterns are monopodial (main stem continues to grow) and sympodial (new shoots take over when the main apex stops growing).

Answer:

1. Bud scales protect buds from damage by physical factors and desiccation.
2. Stems grow in length through cell division and elongation in the apical meristem.
3. Not all buds grow due to apical dominance, hormonal imbalances, and limited resources. Hormonal signals and environmental cues determine which buds grow.
4. Two branching patterns are monopodial and sympodial.
