Use the evidence in the text to select the photosynthetic organism.
Red sea urchins are marine animals covered with hard spines. The urchins' cells take in minerals from the water and use these minerals to form the spines. Thistles are a type of flowering plant covered in prickly spines. Thistle plant cells contain chloroplasts, and their flowers contain a nectar that attracts birds and butterflies.
Organisms that carry out photosynthesis are called photosynthetic organisms. During photosynthesis, these organisms use light energy, carbon dioxide, and water to produce sugars and oxygen.
Photosynthetic organisms also often have the following characteristics:
They are producers, which are organisms that make their own food inside their cells. Because producers make their own food, they typically do not eat other organisms.
Their cells contain chloroplasts, which are cell structures where photosynthesis occurs.
Their chloroplasts often contain a green substance called chlorophyll. Chlorophyll captures light energy from the Sun to power photosynthesis.
They use the sugars they produce during photosynthesis as food. This food provides energy that helps the organisms live, grow, and reproduce.
This organism is photosynthetic:
The text tells you that thistle plant cells contain chloroplasts. This is evidence that the thistle is a photosynthetic organism.
This organism is not photosynthetic:
The text does not provide evidence that the red sea urchin is photosynthetic.
