• B. proteins which control growth
• C. essential nutrients supplied from soil
• D. nucleus and certain minerals in the cytoplasm of plant cells

Answer 1

The correct option is A

genes which control enzyme activity for hormone production

Cellular DNA is the information source for making proteins in the cell. A section of DNA that provides information for one protein is called the gene for that protein. Plant height and its growth is regulated by hormones. Hormone production is in turn controlled by genes which control enzyme activity for hormone production .
