Membrane bound organelles are NOT present in:
Neither eukaryotic nor prokaryotic cells
Only eukaryotic cells
Both eukaryotic and prokaryotic cells
Only prokaryotic cells
Only prokaryotic cells
Membrane-bound organelles (such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, etc.) are characteristic of eukaryotic cells. Prokaryotic cells lack a true nucleus and all membrane-bound organelles.
Membrane-bound organelles (such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, etc.) are characteristic of eukaryotic cells. Prokaryotic cells lack a true nucleus and all membrane-bound organelles.
A prokaryotic cell is like a studio apartment where everything (sleeping, cooking, working) happens in a single open room. A eukaryotic cell is like a large multi-room house with dedicated rooms (kitchen, bedroom, bathroom) enclosed by walls and doors (membranes) for specific functions.
PRO = NO (Prokaryotes No membrane-bound organelles); EU = DO (Eukaryotes Do have membrane-bound organelles).
In prokaryotic cells (bacteria and archaea), all cellular processes take place in the cytoplasm because they lack internal membranes that compartmentalize the cell. In contrast, eukaryotic cells (plants, animals, fungi, and protists) rely on membrane-bound compartments to isolate metabolic reactions, maintain different pH levels, and optimize cellular efficiency.
Prokaryotic cells lack true membrane-bound organelles and a true membrane-bound nucleus.
Ribosomes are present in both prokaryotic and eukaryotic cells, but they are non-membrane-bound (70S in prokaryotes, 80S in eukaryotes).
Eukaryotic cells feature complex compartmentalization with organelles like mitochondria, chloroplasts, endoplasmic reticulum, and Golgi bodies.
