A sac bounded by a single membrane is called a lysosome. This organelle is present only in animal cells and contributes in intracellular digestion.
Vacuoles
No, bacteria do not have membrane-enclosed organelles like eukaryotic cells do. Instead, the internal components of bacteria are not separated by membranes but may be organized by intracellular structures such as ribosomes, nucleoid regions, and plasmids.
Ribosome is a cell organelle not bounded by membrane. It is responsible for protein synthesis in the cell.
A vesicle forms as a small sac from the cell's membrane.
No, peroxisomes do not have a double membrane. They are single-membraned organelles that contain enzymes involved in various metabolic reactions, such as detoxification of harmful substances and fatty acid metabolism.
No, it is not a vacuole membrane. A vacuole is a membrane bound sac with a single membrane called the tonoplast. The solution with in the vacuole is called cell sap which is a combination of organic and inorganic materials. I hope this helps, Dr. Hsiftl
Yes, prokaryotes are organisms that lack a cell nucleus and other membrane-bound organelles, whereas eukaryotes have a true nucleus and membrane-bound organelles. Prokaryotes are usually single-celled organisms like bacteria, while eukaryotes can be single-celled (like some protists) or multicellular (like plants, animals, and fungi).
A dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material
Ribosomes and Centrioles
Bacteria are prokaryotic, microscopic organisms whose single cells have neither a membrane-bounded nucleus nor other membrane-bounded organelles like mitochondria and chloroplasts. The can be rod shaped (bacilli), spheres (cocci), or spiral shaped (spirochetes).
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
The membrane that forms a sac around an animal embryo is called the amniotic sac. The embryonic sac is a bag of fluid inside of a woman's womb where the unborn baby develops and grows.
