Plants use nitrogen for <u><em>making protein</em></u> since proteins are rich in it because of the amino group of the amino acids.
Answer:
d. Plant cells contain a large vacuole that occupies much of the volume of the cell.
Explanation:
The vacuole is a membrane-bound organelle which is often found in plant and fungi cells, as well as in certain bacteria, protists and animal cells. The vacuole is filled with water that forms a solution containing inorganic and organic compounds. The size of the vacuole may vary depending on the requirements of the specific cell type. In plant cells, vacuoles often occupy an important fraction of the overall cell volume and play key roles during growth and development, influencing diverse cellular functions ranging from photosynthesis to transpiration.
Homologous chromosomes are pair of chromosomes, one inherited from father and other inherited from mother, that contain the same genes (but might have different alleles of those genes). Those chromosomes pair up during meiosis (prophase I), where they exchange genetic material during the process of crossing-over. This is where genetic recombination occurs and as a result, daughter cell contains different combinations of maternally and paternally parts.
Chiasmata is a point where two non-sister chromatids belonging to homologous chromosomes touch.
