Solution:

Mouse is an animal cell which is eukaryotic. Nucleolus, ribosomes and centrioles are non-membrane bound cell organelles. The entire endomembranous system (ER, Golgi body, lysosome, vacuole), peroxisomes, cilia, flagella have a single membrane surrounding them. Mitochondria and nucleus are surrounded by two membranes. Mesosomes are infoldings of plasma membrane found in prokaryotes.
