Answer
This statement is incorrect. Specialised cells that secrete proteins, such as plasma cells, do not have a rigid cell wall, as rigid cell walls are characteristic of plant cells and certain prokaryotes.

Answer
This is an incorrect statement. While autophagic cells may have lysosomes, secretory cells generally do not contain numerous lysosomes as their main function revolves around synthesizing and secreting proteins.
Step 3
contain functional chloroplasts.

Answer
This statement is incorrect. Chloroplasts are found in plant cells and are responsible for photosynthesis; therefore, protein-secreting cells typically do not contain chloroplasts.
Step 4
have an extensive Golgi apparatus.

Answer
This statement is correct. Secretory cells have an extensive Golgi apparatus, which is crucial for the modification, sorting, and packaging of proteins for secretion.
