Vascular plants are the ones that posses vascular tissue, sporophyte, and true roots, leaves, and stems.
Explanation:
The vascular plants are land plants. They form a very large group in the plant family, varying in size, shape, color etc. All of the plants in this group share some characteristics that define them as vascular plants, such as having true vascular tissue, sporophyte, and having true roots, leaves, and stems.
Another characteristic of the vascular plants is that they have lignified tissue which have the purpose of distributing the minerals and water throughout all of the plant. Plants that fall into this group are the flowering plants, conifers, ferns, clubmosses, and horsetails, and they are spread out on almost all of the plant when plant life is possible.

Answer:
Option E, Both increased acidity of deep waters and changes in the growth of bottom-dwelling organisms with calcium-carbonate shells
Explanation:
When high concentration of CO2 is pumped into the ocean at its greater depths, CO2 is absorbed extensively by the ocean which changes the pH of ocean water and makes it more acidic. The high acidity of ocean water is due to the release of free hydrogen ions. Excess of hydrogen ions make the carbonate ions less abundant due to which the organism that make carbonate shell will suffer as they may not get sufficient carbonate ions to calcify their outer coverings.
Hence, option E is correct
