Question

1. under a microscope, the cells of mushroom plans, and animals all have visible nuclei. this makes them all...

a. autotrophs b. eukaryotes
b. heterotrophs
c. eukaryotic
d. prokaryotic

1. what trait do the mushroom and gecko share that the tree lacks?

Explanation:

For question 6: Organisms with a visible, membrane-bound nucleus are defined as eukaryotes. Mushrooms (fungi), plants, and animal cells all fit this definition. Autotrophs/producers make their own food (mushrooms and animals do not), heterotrophs/consumers obtain food from other sources (plants do not), and prokaryotes lack a membrane-bound nucleus.
For question 7: Mushrooms (fungi) and geckos (animals) cannot produce their own food, so they are heterotrophs that must consume or absorb nutrients from other organisms. Trees (plants) are autotrophs that make their own food via photosynthesis, so they lack this heterotrophic trait.

Answer:

1. c. Eukaryotic
2. They are heterotrophs (cannot produce their own food, must obtain nutrients from other organisms)
