Question

use the photosynthesis interactive to answer the question. suppose that you conduct an experiment to determine how photosynthetic output, measured in oxygen (o₂) production, changes as you alter photosynthesis, and generate the graph. identify which manipulations to photosynthesis generated the observed changes in o₂ production depicted in the graph. answer bank high o₂ high temperature green light high co₂

Explanation:

Step1: Understand photosynthesis factors

Photosynthesis is affected by light, temperature, and gas concentrations.

Step2: Analyze light - Green light

Plants reflect green light and absorb other colors more effectively for photosynthesis. Green light thus reduces photosynthetic output and oxygen production.

Step3: Analyze temperature - High temperature

High temperatures can denature enzymes involved in photosynthesis, reducing the rate of photosynthesis and oxygen production.

Step4: Analyze gas concentrations - High O₂

High O₂ can cause photorespiration in some plants, which reduces the efficiency of photosynthesis and oxygen production. High CO₂ generally increases photosynthetic output and oxygen production, but here we are looking for factors reducing it.

Answer:

high O₂, high temperature, green light
