1. a cellular structure found in plant but not animal cells is the:

Explanation:

1. The cis - face of the Golgi complex receives vesicles from the endoplasmic reticulum (ER).
2. The Golgi complex is responsible for sorting, processing, and packaging molecules.
3. The Golgi complex plays a vital role in packaging materials for secretion.
4. The structures indicated in the figure are likely cristae, which are folds in the inner - mitochondrial membrane.
5. Cristae are the site of ATP production through the conversion of food molecules in cellular respiration.
