- a) How does the tissue organization in eudicots relate to secondary growth in stems? What is the role of the vascular cambium in secondary growth of eudicot stems?
- b) How does secondary growth in eudicot stems contribute to supporting the bodies of woody plants?
Homework Answers
a. After the cell elongation in apical meristem, primary growth of stem takes place. It happens in all seed plants. In conifers and dicots, secondary growth happens in meristems called the vascular cambium and cork cambium produces vascular tissues and expands the thickness of stems or girth of stem after some time.
Vascular cambium produces secondary xylem and phloem that thickens the stem and cork cambium forms the hard outer covering as a part if secondary growth.
In woody plants, cork cambium becomes the outermost lateral meristem.

In plants, germ cells are derived from tissues late in plant growth. How does this fact relate to inheritance patterns observed in plants versus animals? a. This explains the presence of Barr bodies found in the cells of animals but not in plants. b. This explains why some genes in both the egg and sperm of animals contain special methylation patterns, whereas in plants all gametes have the same methylation patterning. c. This explains why epigenetic modifications are heritable in...

At first, use the microscope's 10x objective, then switch to the 43x objective. With the 10x objective in place, note the variation in size and orientation of the veins (vascular bundles), which contain the two vascular (conducting) tissues, xylem and phloem. The centrally located largest vein is the midvein. The midvein and...
