1. What is apical growth ?
Apical growth is is a special meristematic tissue at the tips of the shoots and roots, and often of the leaves of vascular plants. It is responsible for the increase of in height of plants known as primary growth and some are located at vascular cambium.
2. What is the function of the vascular bundles in stem ?
Vascular bundles arranged itself to form a ring like structure within the schlerenchyma or strengthening cells called budle sheath. Vascular bundles divided into three parts namely; xylem, phloem, and vascular cambium.
3. What are the differences in the internal structure of Monocot and Dicot Stem?
4. why do most monocots have narrow stems ?
5. How would you explain the increase of diameter but not in height of trees that have been prune (the tips of their branches are cut)?
6. What is the significance o modified stems , such as rhizomes and corns, in relation to the survival of a plants ?
The internal structure of the Monocot and Dicot has only slight difference. For instance,the arrangement of vascular tissue of Monocot stems appears as a cental ring of alternating group of large xylem and small phloem. While Dicot stem it appears to be x-shaped in arrangement in the center,consist a thicked walled xylem and thin walled phloem.
This is due to the arrangement of their tissue. For instance, the arrangement of the xylem and phloem are in circular motion.
Plants produce modified stems so they can survive a cold or dry period which normally in a period of inactive growth and when the cold and dry period is over, the plants begin a new growth from underground stem.
If the tips of the branches/shoots that have been cut, usually happened is the increase of their diameter. This is due to that apical meristem is cut away so therefore there will be slowing in the increase of height and faster growth in the girth/ diameter.
