Photosynthesis：練習問題

Marine producers like red algae inhabit deeper waters. Which accessory pigments allow them to absorb the blue-green light that penetrates most deeply into the ocean?

Why do many marine producers, such as red algae, possess accessory pigments like phycobilins in addition to chlorophyll a?

An action spectrum for a green macroalga shows two distinct peaks. Which of the following best describes the relationship between an absorption spectrum and an action spectrum?

Which of the following colors of light is absorbed most rapidly by the upper layers of the ocean water, making it unavailable for producers at greater depths?

A researcher investigates the rate of photosynthesis in a marine plant. If the temperature is increased from \(15^{\circ}\text{C}\) to \(45^{\circ}\text{C}\) while keeping light and carbon dioxide levels constant, the rate of photosynthesis eventually decreases sharply. What is the most likely explanation for this decrease?

State the balanced chemical equation for the process of photosynthesis, using MathJax to represent the molecular formulas.

Explain the importance of accessory pigments, such as xanthophylls and phycobilins, for marine producers living in deeper ocean waters where light penetration is limited.

State the relationship between the wavelength of light and its penetration depth in the marine environment and identify which color of light is absorbed first in the upper layers of the ocean.
