A.)Well–developed vascular system
Vascular plants help maintain the water cycle. The property of these plants
enables them to carry out this function is their well-developed vascular system.
These type of plants are more evolved and developed than nonvascular plants
because of its specialized characteristics like xylem, which is a tissue that
is responsible for its framework and not only that, it is also has a greater mechanism
for water transference. Another is phloem, which is responsible for food
conduction.
        
             
        
        
        
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.

Answer;
Kingdom, Division, Class, Order, Family, Genus and Species
Explanation; 
-The plant kingdom is divided into three divisions namely Bryophyta, Pteridophyta and Spermatphyta.
-Division Bryophyta includes mosses and liverworts. Division Pteridophyta includes the ferns and horsetails. They show a greater variety and a greater ability than bryophyte.
-Division Spermatophyta comprises all the seed bearing plants. They are familiar green plants which produce seeds through flowers or cones. The division spermatophyte consists of two main subdivisions: Gymnospermatophyta and Angiospermatophyta, which are the divided into classes and so forth,.
