A Level Biology Practice Exam

What type of organisms fall under the category of eukaryotes?

1. Only single-celled organisms

2. Multicellular eukaryotic organisms and some prokaryotes

3. Multicellular eukaryotic organisms like animals, plants, fungi, and single-celled protoctista

4. Only animals and plants

The correct answer is: Multicellular eukaryotic organisms like animals, plants, fungi, and single-celled protoctista

Eukaryotes are characterized by having complex cells with a defined nucleus and membrane-bound organelles. In the context of this question, the correct answer encompasses a wide range of organisms that all fit into the eukaryotic category. This includes multicellular organisms such as animals and plants, which are well-known examples of eukaryotes. Additionally, it includes fungi, which have unique cellular structures and play important ecological roles. Single-celled eukaryotes like protoctista (also referred to as protists) are also included in this classification. These organisms can be quite diverse, ranging from amoebae to algae. Therefore, the answer accurately reflects the correct classification of various groups of living organisms that fall under the eukaryotic domain, highlighting the diversity and complexity of life forms that possess eukaryotic cells.
