□ plasma membrane
□ genetic material
□ cytoplasm

3 multiple answer 2 points
name 2 structures only eukaryotic cells have. (refer to figure 3.1)
□ organelles
□ nucleus

Explanation:

1. For question 1, the three core tenets of Cell Theory are the standard established principles of cell biology.
2. For question 2, these three structures are universal to all cells, as they are essential for basic cellular function regardless of cell type.
3. For question 3, eukaryotic cells have membrane-bound organelles and a nucleus, which prokaryotic cells lack (prokaryotes have non-membrane-bound structures and their genetic material is not enclosed in a nucleus).
