Cellular organelles with membranes are -

  1. endoplasmic reticulum, ribosomes and nuclei
  2. lysosomes, Golgi apparatus and mitochondria
  3. nuclei, ribosomes and mitochondria
  4. chromosomes, ribosomes and endoplasmic reticulum

Answer

(2) lysosomes, Golgi apparatus and mitochondria

Solution

Ribosomes are non-membranous granular structures, and chromosomes are not membrane-bound organelles.

⇒ Every option containing ribosomes or chromosomes is excluded.

∵ Lysosomes (single membrane), Golgi apparatus (single membrane) and mitochondria (double membrane) are all membrane-bound.

Answer: (2)
