Question

1. not all parts of the organisms that carry out photosynthesis are capable of performing photosynthesis, much like not all parts of the human body are capable of digesting food that ability is only possible by some parts of the body. identify the area of a producer that can perform photosynthesis and why.

roots; theyre under ground
braches; theyre closer to the sun than the trunk
trunk; theyre protected by layers of bark
leaves; they contain the light - absorbing pigments

Explanation:

To determine the correct answer, we analyze each option:

• Roots: Roots are underground and lack light - absorbing pigments needed for photosynthesis, so they can't perform photosynthesis.
• Branches: While branches may be closer to the sun, the key factor for photosynthesis is the presence of light - absorbing pigments (like chlorophyll), not just proximity to the sun. Also, the option's reasoning is not the core reason for photosynthesis ability.
• Trunk: The trunk is protected by bark and generally does not have the necessary light - absorbing pigments in sufficient quantity (or at all in most cases) to perform photosynthesis.
• Leaves: Leaves contain chlorophyll (light - absorbing pigments) which is essential for capturing light energy, and they have a large surface area exposed to light, along with other structures (like stomata for gas exchange) that are necessary for photosynthesis. So leaves are the part of the producer (plant) that can perform photosynthesis because they contain light - absorbing pigments.

Answer:

D. leaves; they contain the light - absorbing pigments
