The correct answer is C) a one-celled algae that has a stiff cell wall.
To arrive at the correct answer, first, we need to understand what a diatom is. A diatom is a type of single-celled organism that belongs to a group called algae. These algae are characterized by their unique feature of having a stiff and protective outer covering, known as a cell wall. It is this characteristic that distinguishes diatoms from other types of algae.
To find the answer to this multiple-choice question, let's consider the options:
A) The green chemical that allows plants to create their own food: This option refers to chlorophyll, which is responsible for the green color in plants. However, while diatoms use chlorophyll for photosynthesis just like plants do, this option does not accurately describe a diatom.
B) Simple organisms like mushrooms and molds: This option refers to fungi, which are not related to diatoms. Fungi have a different cellular structure and do not possess the unique characteristics of diatoms.
C) A one-celled algae that has a stiff cell wall: This option accurately describes diatoms. They are one-celled organisms, classified as algae, and have a stiff cell wall that provides structure and protection.
D) An infectious disease carried by mosquitoes, harmful to humans: This option describes a type of disease, commonly known as malaria, which is caused by a parasite transmitted through mosquito bites. It is unrelated to diatoms.
E) Single-celled organisms such as some forms of algae: While this option mentions single-celled organisms like algae, it does not specify the characteristic feature of a stiff cell wall. Therefore, it does not accurately describe diatoms.
By considering the options and understanding the description and characteristics of diatoms, we can confidently conclude that the correct answer is C) a one-celled algae that has a stiff cell wall.
