1. The question asks which structure is not part of the endomembrane system. The endomembrane system includes the endoplasmic reticulum, Golgi apparatus, and plasma membrane. Chloroplasts are not part of this system; they are involved in photosynthesis in plant cells. Therefore, the correct answer is a. Chloroplast.2. The question asks which structure is common to both plant and animal cells. Chloroplasts are specific to plant cells for photosynthesis, the wall made of cellulose is also specific to plant cells, and the central vacuole is generally larger in plant cells and serves different functions. Mitochondria, however, are present in both plant and animal cells and are responsible for cellular respiration. Therefore, the correct answer is d. Mitochondrion.3. The question asks which structure-function pair is mismatched. The nucleolus is actually involved in the production of ribosomes, not the storage of hereditary material. That function is served by the nucleus. Lysosomes are involved in intracellular digestion, ribosomes in protein synthesis, and the Golgi apparatus in protein processing and secretion. Therefore, the mismatched pair is a. Nucleolus; storage of hereditary material.4. The question is incomplete, but it seems to be asking where cyanide will be found if it binds to a molecule involved in a certain process. Cyanide inhibits cellular respiration by binding to a molecule in the electron transport chain, which occurs in the mitochondria. Therefore, the correct answer, based on the information given, is a. Mitochondria.
