Answer: Hypothalamus
The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.
Explanation:
Since the hypothalamus controls the secretion of hormones from the pituitary gland, and the pituitary gland, also known as master gland, controls the activities of all other glands like the following:
- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics
- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.
Thus, hypothalamus plays important role in puberty
Answer:
The thylakoid membrane is responsible for separation of different regions of the mitochondrion and the chloroplast.
This membrane is responsible for the major difference between chloroplasts and mitochondria in terms of their structure and function.
The membrane is very important in chloroplasts and it fills the role of the inner mitochondrial membrane in electron transport and the chemiosmotic generation of ATP.
Kingdom plantae is the only kingdom that contains all of those characteristics
