Question

question 16 (1 point)
photosynthesis takes place mostly in
photoautotrophs
the leaf.
the chloroplast.
mesophyll.
all of these.
question 17 (1 point)
longer wavelength photons have
larger amounts of energy.
a standard amount of energy.
almost no energy.
smaller amounts of energy.
a distinct amount of energy.

Explanation:

• For Question 16: Photoautotrophs are organisms that perform photosynthesis. Leaves are the main organs where photosynthesis occurs. Chloroplasts are the organelles within plant cells where the process takes place. Mesophyll cells in the leaf contain many chloroplasts and are the main sites of photosynthesis. So all are correct.
• For Question 17: The energy of a photon is inversely - related to its wavelength according to the formula $E = \frac{hc}{\lambda}$, where $E$ is energy, $h$ is Planck's constant, $c$ is the speed of light, and $\lambda$ is the wavelength. So longer - wavelength photons have smaller amounts of energy.

Answer:

Question 16: E. All of these
Question 17: D. smaller amounts of energy
