Activation energy is required to start a chemical reaction. Activation energy is the energy needed to allow the reactant to react. Activation energy is measured in Joules (J).
Alyssa's additional observation would be cell Y having a larger vacuole than cell X. The third option is the correct one.
<h3>Plant cell vs animal cell</h3>
From the observations, both cells are eukaryotic. This is because:
- cell X has lysosomes which are only found in eukaryotic cells
- cell Y has a nucleus which also peculiar to eukaryotic cells only
Lysosome houses digestive enzymes and is found mostly in animal cells. Only a few plant cells have lysosomes.
Thus, the lack of a lysosome means that cell Y is a plant cell while the presence means that cell X is an animal cell.
Generally, plant cells have larger vacuoles than animal cells.
