How many cell layers make up the onion tissue?
There is only a single layer of cells in onion tissue. However, sometimes the tissue can fold over itself and appear to have two layers.
How many cell layers make up the onion cell?
The main part of an onion, the thick layers, can have many layers of cells stacked on top of each other. Between the layers, there is a thin skin (onion skin) which is a single layer of cells. The single layer makes it easy to for a student to study the cell structure under a microscope.
What are two layers of phospholipid?
The two layers of phospholipids that make up the cell membrane are the hydrophilic head facing outward towards the aqueous environment, and the hydrophobic tail facing inward towards the interior of the membrane. This bilayer structure provides a barrier that controls the movement of substances in and out of the cell.
What is the cell membrane what does it do for the cell and what is it made of?
The cell membrane acts as the walls, floor and ceiling or covering that surrounds the cell and determines what is "inside" the cell and what is "outside". It is made of a lipid bilayer (two layers) of lipoproteins (fats+proteins). These are very fluid and to make it steadier cholesterol molecules are imbedded in it. There are also proteins in the membrane that acts as doors or windows. They allow some things in and out.
What is the key structural element of a cell membrane?
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.

What does an onion cell look like after adding a salt solution NaCl?
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
The cell membrane and the nuclear membrane are made of?
the cell membrane, also known as the plasm membrane, forms a boundary between a cell and the enviroment and is made of a double layer of phospholipids. A phospholipid is made of a charged phosphate group, a glycerol, and two fatty acid chains.
What is the shape and color of the onion cell?
When observing an onion cell under the microscope, it appear to be long an oval in shape. Staining the cell will make the chromosomes attain a deep purple color.
Layers that make up the cell membrane?
The cell membrane is composed of a phospholipid bilayer, which consists of two layers of phospholipid molecules oriented with their hydrophilic heads facing outward and their hydrophobic tails facing inward. Embedded within this bilayer are proteins that perform various functions such as transport, signaling, and structural support. Additionally, cholesterol molecules are interspersed within the phospholipid bilayer to help maintain its fluidity and stability.
