Which of the following is correct? (a) Cells of all living organisms have a nucleus. (b) Both animal and plant cells have a well defined cell wall. (c) In prokaryotes, there are no membrane bound organelles. (d) Cells are formed de novo from abiotic

Solution:The correct statement is option c

Prokaryotes are organisms that lack membrane bound organelles.Presence of membrane bound organelles is a feature of eukaryotes.Eukaryotes contain cell organelles like mitochondria,endoplasmic reticulum,Golgi bodies,chloroplasts,nucleus etc.

Ribosomes are non membrane bound organelles found in both prokaryotes and eukaryotes.

Functions of cell organelles

• Nucleus-Act as a control centre to regulate cellular activities of cell

• Endoplasmic reticulum-Transport of materials

• Mitochondria-Aerobic respiration

• Chloroplast-Trapping of light energy to carry out photosynthesis

• Ribosomes-Synthesis of proteins

• Golgi bodies-Packing of materials
