4.Name the two organelles in a plant cell that contain their own genetic material and ribosomes.
5.Why are lysosomes also known as"scavengers of the cells"?

Answer:
Bacterial cells are primitive cells hence, called as prokaryotic cells. They do not possess membrane bound organelles as mitochondria, lysosomes, etc. They also do not have well-defined membrane bound nucleus.
Onion peel cell is an eukaryotic cell with well-defined membrane bound nucleus, membrane bound organelles as mitochondria, vacuole, etc.
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.
Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm.
Both, mitochondria and plastid possess their own genetic material and ribosomes. The mitochondrial DNA and plastid DNA possess genes, which produce the proteins necessary for the functioning of mitochondria and plastids respectively.
Lysosomes are single membrane bound cellular organelles. They possess many hydrolytic enzymes that destroy any foreign material inside the cell such as bacteria. ... As lysosomes remove unnecessary particles and organelles from cell hence they are called as scavengers of the cells.
Answer:
bacterial cell is a cell of bacteria however you know that bacteria is a microorganism that are of two types good and bad and overall it is different from onion peel cell because it is cell of vegetable
