Question

1. what is true about chloroplasts?

ribosomes attached to the outer membrane to aid in protein production
contain a green pigment that captures sunlight
found in plant and animal cells
perform photosynthesis; create glucose using sunlight

Explanation:

• Ribosomes on chloroplast outer membrane: Chloroplasts have their own ribosomes, but ribosomes attached to outer membrane for protein production is not a defining chloroplast trait (ER has ribosomes for that).
• Contain green pigment (chlorophyll) to capture sunlight: True, chlorophyll in chloroplasts absorbs sunlight for photosynthesis.
• Found in plant and animal cells: False, chloroplasts are in plant cells (and some protists), not animal cells.
• Perform photosynthesis (create glucose with sunlight): True, chloroplasts are the site of photosynthesis, converting light energy to glucose.

So the true statements are "contain a green pigment that captures sunlight" and "perform photosynthesis; create glucose using sunlight". (For the checkbox, mark these two.)

Answer:

• contain a green pigment that captures sunlight (checked)
• perform photosynthesis; create glucose using sunlight (checked)
