Question

how is a bacterial cell different from onion peel cell? how do substance like carbon dioxide and water move in and out of the cell?​

Answer 1

Answer:

i) Bacterial cell is prokaryote and onion cell is eukaryote

Bacteria lack membrane bound cell organelles but onion peel has all membrane bound cell organelles.

Bacterial genetic material is free flowing and onion peel has its genetic material inside a membrane bound nucleus.

ii) The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. When the concentration of CO2 and water is higher in external environment than that inside the cell, CO2 and water moves inside the cell

IF THE SAME PROCESS TAKES PLACE IN LIVING ORGANISIMS IT IS CALLED AS OSMOSIS
