Question

coral have a symbiotic relationship with *
diatoms
detritus
angiosperms
symbiodinium

chlorophyll b is used for _.
capturing light
creating atp
duplicating dna
gathering water

Explanation:

• Coral and Symbiodinium: Corals have a mutualistic (symbiotic) relationship with Symbiodinium (zooxanthellae). The algae live within coral tissues. They perform photosynthesis, providing the coral with organic products like glucose, glycerol, and amino acids. In return, the coral provides the algae with a protected environment and nutrients (such as carbon dioxide for photosynthesis).
• Diatoms: Diatoms are a type of algae, but they do not form the specific symbiotic relationship with corals that Symbiodinium does.
• Detritus: Detritus is dead organic material. It is not an organism that forms a symbiotic relationship with corals.
• Angiosperms: Angiosperms are flowering plants. They are not involved in a symbiotic relationship with corals.
• Chlorophyll B and Light - Capturing: Chlorophyll B is an accessory pigment in photosynthetic organisms (like plants and algae). Its role is to capture light (specifically light in the range of wavelengths that it can absorb, which is different from chlorophyll A). It then passes the energy from the captured light to chlorophyll A (the reaction - center pigment) for the light - dependent reactions of photosynthesis.
• ATP Creation: ATP (adenosine triphosphate) is created during processes like cellular respiration (in mitochondria) and the light - dependent reactions of photosynthesis. Chlorophyll B is not directly involved in ATP creation; its role is in light - capture.
• DNA Duplication: DNA duplication is part of the cell - cycle (e.g., in mitosis or meiosis). Chlorophyll B has no role in DNA duplication.
• Water Gathering: Structures like roots in plants are involved in gathering water. Chlorophyll B is a pigment and not involved in water - gathering.

Answer:

• For "Coral have a symbiotic relationship with": Symbiodinium
• For "Chlorophyll B is used for": Capturing Light
