The cells of plants and animals are similar, except for a few different structures. which structures are only found in plant cells?
endoplasmic reticulum
ribosomes
chloroplasts
lysosomes
peroxisomes
vesicles
large central vacuole
golgi complex
cytoskeleton
mitochondria
cell wall

Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.

Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.

Cell walls also maintain structure and rigidity.

Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
