Question

multiple choice question
identify the organelle labeled a.
o nucleus
o lysosome
o rough er
o golgi complex
o mitochondrion

Explanation:

To identify the organelle labeled 'A', we analyze the structure: the organelle has a series of flattened, membranous sacs (cisternae) and is involved in processing and packaging proteins, which matches the Golgi complex. The nucleus is a large, round structure with chromatin, lysosomes are small vesicles, rough ER has ribosomes on its surface, and mitochondria have a double - membrane with cristae. So the organelle labeled 'A' is the Golgi complex.

Answer:

D. Golgi complex
