A sperm cell's structure is very specialized. Its flagellum is used for locomotive function, to rapidly swim directly through the egg cell. While the cytoplasm, it contains organelles, such as the Mitochondria, wherein respiration occurs, to release the energy needed for the sperm's journey towards the egg cell. Sperm cells, contain special enzymes known as acrosomes, this special enzymes allows the sperm to break through the cell membrane of the egg.

Explanation:
Answer:
A considerable increase in phytoplankton populations in winter, and a greater increase in spring due to increase in light intensity.
Explanation:
Nitrogen and phosphorus are important nutrients required by phytoplankton populations. The growth of phytoplankton populations is dependent on the level of the availability of Nitrogen and Phosphorus in the presence of sunlight.
A rise in the aquatic coastal levels of nitrogen and phosphorus would result in a great increase in phytoplankton populations in spring, as stimulated by nutrient enrichment coupled with the availability of sunlight during spring. Phytoplankton populations would increase also in winter but not as high when compared to the rise in population in spring
