Answer:
E) spores
Explanation:
The plant kingdom is divided into the five phyla which can be distinguished on the basis of the defining features shown by the plants.
In the given question, the features like the cell walls made of cellulose, chlorophylls a and b and the dominant sporophyte show that the plant belongs to a higher group. The plants in which the sporophyte is dominant are known may belong to the pteridophyte, angiosperms or angiosperms.
The spores are produced by these sporophytic structures of higher plants that do not form in the large size gametophyte but reduced gametophyte or microscopic gametophyte, therefore, is least useful to the classification.
Thus, E) spores is the correct answer.
D. Somatic Cell.

Purple loosestrife has the ability to severely decrease biodiversity wherever it grows due to its ability to displace many native plants. This not only affects the native plants themselves, but also any animal species which feed, nest, or take cover in wetland plants; the purple loosestrife forms such dense thickets that it is impossible for these animals to enter or use them. These animals are also displaced, then, by the loosestrife. Many of these animals, mostly birds, are highly valued aesthetically, and their disappearance is noticed by humans. On the other hand, though, humans also tend to find the loosestrife aesthetically pleasing; it was introduced as a decorative plant. Still, the damaging effect that the loosestrife has on ecosystem biodiversity is visible, and thus the plant offends any human values of conservation for the sake of conservation, a dominant cultural paradigm, and so the loosestrife is considered detrimental.
Average kinetic energy is directly proportional to temperature, so when kinetic energy decreases so does temperature and when kinetic energy increases so does temperature.
1. it is universal.
2.it also helps in recognisation of any new organism discovered.
3.the scientific name are usually descriptive and also indicate some important characters of the organism.
