question 25 of 32
cell components with double membranes and dna
cell components with single membranes and no dna
cell component with no membrane
answer bank
mitochondria
chloroplast
endoplasmic reticulum
ribosome
nucleus
lysosome
vesicle

Explanation:

• Double membranes + DNA: Nucleus (stores genomic DNA), mitochondrion/chloroplast (have own circular DNA).
• Single membranes + no DNA: Endoplasmic reticulum (lipid synthesis), lysosome (digestion), vesicle (transport) lack DNA.
• No membrane: Ribosomes (protein synthesis) are made of RNA/protein, no membrane.

Answer:

Cell components with double membranes and DNA: nucleus, mitochondrion, chloroplast
Cell components with single membranes and no DNA: endoplasmic reticulum, lysosome, vesicle
Cell component with no membrane: ribosome
