It is a selectively permeable membrane that allows certain substances in and out, but keeps harmful substances from entering the cell. It could be compared to the security guard at the door of an airport that makes sure that nobody dangerous gets in or out.
What else can I help you with?
What cell organelle is responsible for manufacturing of membranes and products?
Endoplasmic Reticulum
Are aquaporins transport proteins responsible for facilitating the movement of water across cell membranes?
Yes, aquaporins are transport proteins that facilitate the movement of water across cell membranes.
What cell organelles lack membranes as part of their structure?
Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
Do ribosomes have cell membranes?
No, ribosomes do not have cell membranes. Ribosomes are organelles responsible for protein synthesis in cells and are made up of ribosomal RNA and proteins. They are typically found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
Do cell membranes make nutrients for cells?
Cell membranes do not make nutrients for cells. They are primarily responsible for controlling the entry and exit of substances into and out of the cell, as well as maintaining the cell's internal environment. Nutrients are typically obtained from the external environment through processes such as diffusion or active transport.
What is an endoplasmic reticulum that has ribosomes?
Actually this is a cell organelle which is an intricate system of tubular membranes in the cytoplasm of a cell. It is responsible for the synthesis and transport of materials to and from cells.
Do cheetahs have cell walls or membranes?
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
Jesse was looking at a cell through a microscope and saw mitochondria and cell membranes what could Jesse say about the cell?
Jesse could say that the cell is likely a eukaryotic cell, as mitochondria are organelles found in eukaryotic cells. The presence of cell membranes suggests that the cell is a structural unit of a living organism, responsible for maintaining its integrity.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
Does calcium depolarize or hyperpolarize cell membranes?
Calcium depolarizes cell membranes.
Do plants have cell membrane?
Plants have cell membranes just inside their cell walls. The cell membranes control what passes into and out of the cell.
