Dive into essential concepts in biology such as the characteristics that differentiate eukaryotes from archaea and bacteria, the kingdoms within the domain Eukarya, and adaptations that allowed plants and animals to thrive in different environments. Learn about major adaptations, body plans, and the significance of bilateral symmetry in the animal kingdom.

What is a major characteristic that makes eukaryotes different from archaea and bacteria ? A. Eukaryotes cells have cell walls. B. Eukayotes cells do not have cell walls. C. Eukayotes cells have a nucleus and organelles. D. Eukaryotes cells do not have a nucleus or organelles.
What are the characteristics of plants that separate them from protists and fungi? A. Plants have cells with cell walls B. Plants are multicellular eukaryotes C. Plants use photosynthesis to make energy D. All of these are characteristics of plants
What was NOT a major adaptation that allowed plants to live on dry land? A. Seeds B. Bilateral symmetry C. Vascular system D. None of these are adaptations to living on land.
What are the three animal body plans we see today? A. Animals, plants, fungi B. Amorphous, vertebrates, mammals C. Unvascularized, vascularized, closed circulatory system D. Amorphous, radial symmetry, bilateral symmetry
Why is bilateral symmetry an important adaptation in animals? A. Because it is helpful in finding food and avoiding predators. B. Because it led to the development of tissues. C. Because animals could not be predators until they became bilaterally symmetric. D. All of the above.
How do fungi decompose other organisms? A. They secrete digestive enzymes to break down organic matter and then absorb it through hyphae. B. They find dead organisms and then grow their roots inside to break the tissues into smaller pieces.
What role do fungi play in an ecosystem? A. Fungi break organic material into smaller particles which releases trapped nutrients. Fungi form symbiotic relationships with trees which helps the trees absorb water and nutrients. Fungi live in and on animals and can cause health problems. D. All of the above. B. C.
What do fungi and arthropods have in common? A. They both have exoskeletons B. They are both bilaterally symmetric C. They both have structures made of chitin D. They both form spreading masses called mycelium
Why are protists difficult to classify A. Because they are constantly changing their characteristics Because they are very small and difficult to see well enough to classify Because they do not have any traits in common with one another D. Because they share some but not all features with plants, animals, and fungi B. C.
What do protists have in common? A. They are usually found in wet habitats because they are susceptible to drying out B. They are all unicellular C. They all photosynthesize D. They all cause disease
