Which of the following do not play a role in intra cellular movement?
Correct answer: C. Inter mediate filaments and micro tubules
- A. Microfilament and inter mediate filaments
- B. Microfilaments and microtubules
- C. Inter mediate filaments and micro tubules
- D. Only microfilaments
Explanation
The functional roles for microfilaments involve cell membrane motility, endo- and exocytosis, secretion and vesicle transfer so option A,B,D are incorrect leaving with C being the correct option as microtubules and intermediate filaments, form the cell cytoskeleton

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
