Answer 1

1. The vascular bundles of dicots is organized in a ring. In monocots it is scattered. So check the vascular bundles.

2. Herbaceous stems contain chlorophyll that allows the plant to use them in addition to leaves for photosynthesis, more green pigment means more food for the plant.

Woody stems allow the plant to grow higher against gravity and not crack due to outside influences.

3. It provides a location on the plant where buds can form and grow into leaves.

4. Permits gas exchange. No, not all stems, only ones with bark.

5. It holds water, so probably water.

6. Lower part because the apical meristem is where it grows. So older things would appear to be at the lower area.

8. That is the place where ALL the plant growth occurs.

10. Because it needs to secrete.
