Chlorophyll

A)an infectious disease carried by mosquitoes, harmful to humans
B)the green chemical that allows plants to create their own food
C)simple organisms like mushrooms and molds
D)single-celled organisms such as some forms of algae
E)a one-celled algae that has a stiff cell wall

B)the green chemical that allows plants to create their own food

Plants that receive their food from hosts are called _____.

invitees
parasites
guests
hostess'
donors

parasites

The correct answer is B) the green chemical that allows plants to create their own food.

To arrive at this answer, you can follow these steps:

1. Understand the question: The question is asking about chlorophyll, so we need to find the option that best describes chlorophyll.
2. Eliminate irrelevant options: Options A, C, and D mention infectious diseases, simple organisms, and single-celled organisms, respectively, which are not directly related to chlorophyll. So we can eliminate these options.
3. Evaluate the remaining options: Option E mentions a one-celled algae with a stiff cell wall, but this doesn't capture the full essence of chlorophyll. Chlorophyll is a pigment found in plants and other photosynthetic organisms, not just in a specific type of algae. Therefore, option E can also be eliminated.
4. Choose the correct answer: Among the remaining options, B) the green chemical that allows plants to create their own food, best describes chlorophyll. Chlorophyll is responsible for capturing sunlight during photosynthesis, enabling plants to convert carbon dioxide and water into glucose and oxygen.

So, the correct answer is B) the green chemical that allows plants to create their own food.
