Which of the following statements is correct regarding hypothalamic control of pituitary function?

The hypothalamus regulates the function of the anterior pituitary by means of the hormones it secretes into the portal vessels of the hypothalamo- hypophyseal system. Blood flows from the hypothalamus to the anterior pituitary gland. The quantities of hormones secreted are very small and cannot be detected in the general circulation.

The correct Option is "All the hypothalamic hormones are synthesized and secreted by neurons"

What happen to the chloroplast pigment when they absorb light?

Light reaction begins with the PS-II. In photosystem-II the reaction centre chlorophyll-a absorb 680 nm. wavelength of red light causing electrons to become excited and jump into orbit further from the nucleus. These electrons are picked up by an electron acceptor, which passes them to an electron system consisting of cytochromes
