What part of a plant cell captures light energy?Multiple choice question.water moleculescellulose in the cell wallATP synthasepigment molecules

Break Down the Problem

1. Identify the choices provided in the question.
2. Determine which component of a plant cell is primarily responsible for capturing light energy.

Relevant Concepts

1. Plant cells contain chloroplasts, which house pigment molecules like chlorophyll that are essential for photosynthesis.
2. Other options such as ATP synthase and cellulose do not play a direct role in capturing light energy.

Analysis and Detail

• Water Molecules: These are involved in the photosynthesis process but do not capture light energy themselves.
• Cellulose in the Cell Wall: This provides structural support and does not capture light energy.
• ATP Synthase: This enzyme helps in the production of ATP but is not involved in the initial capturing of light energy.
• Pigment Molecules: Chlorophyll is the key pigment molecule located in chloroplasts that absorbs light energy, particularly in the blue and red wavelengths.

Verify and Summarize

The correct answer is the option that directly relates to the capture of light energy in plant cells. After analyzing all choices:

Final Answer

Pigment molecules are responsible for capturing light energy in a plant cell.
