When a unit in a crystal lattice has lattice points only at its corners ,it is called a simple or primitive unit cell. There are seven types of primitive unit cells among crystal.They are
1. Cubic unit cell
2. Tetragonal unit cell
3. Orthorhombic unit cell
4. Monoclinic unit cell
5. Rhombohedral unit cell
6. Triclinic unit cell
7. Hexagonal unit cell
And, the smallest repeating unit in space lattice which when repeated over and over again produces the complete space lattice.This is called unit cell.
In easy form , The unit cell which do not contain any interior point are called primitive unit cell.
The Unite Cell is the smallest group of atom showing the characteristic lattice structure of a particular metal. It is the building blockof a single crystal.
A single crystal can have many unit cells.
That elements combine in certain properties because they are made of single cell atoms
of crystals.

Crystal Violet staining is a technique used in cell culture laboratories to determine concentration of cells in culture liquid. As against other means of cell staining and counting (e.g. Trypan blue) the entities counted using the Crystal Violet staining are the cell nuclei instead of whole cells. This technique has the advantage that also concentrations of aggregated cells can be determined accurately. Here comes the Citric acid in. Nuclei are situated within the cell. To extract the nuclei out of the cells Citric acid is used to make the cell burst so that the Crystal Violet can stain the nuleus and thus concentration of cells can be determined using a microscope and a counting chamber.
a single cell is more differentiated
No
The question answers itself. Single cell referencing is when you reference a single cell. Range referencing is when you reference a range of cells.
THE BODY HAS MANY CELLS WHICH MAY BE CALLED MULTICELLAR AND A SINGLE CELL IS KNOWN AS A UNICELLAR.
The human body and a cell both show similarities in terms of co-ordination. Both have a co-ordianting centre(Brain in human body and nucleus in cell). Both show division of labour(Different organ systems in human beings perform different functions while in cell different organelles perform different functions).
reproduction
paramecium cells can not survive on its own because it works as a group while on the other hand, the Elodea cells can live on their own because they are single cells.
three reasons why a root hair cell different is different from a leaf
It means what it says. A cell which appears a bit different from a typical cell with signs of degeneration
Thousands of different enzymes
VLSI (very large scale integration) technology places tens of thousands of transistors (and their interconnections) on a very pure single-crystal chip of silicon.A single solar cell is just ONE very largearea junction diode, operating in self produced reverse bias mode.A common kind of solar cell starts with the same very pure single-crystal silicon, but the later processes are different from VLSI manufacturing processes.Solar cells don't include any transistors,So you could say that single-crystal solar cell uses one small part of VLSI technology, plus a bunch of its own unique processes.Other kinds of solar cell use cast polycrystalline silicon or amorphous silicon or some other starting material.As of 2007, the highest-efficiency solar cells use 3-junction gallium arsenide instead of silicon.Their manufacturing processes are even less like VLSI manufacturing.
CTRL is just the common name of the Control key on your computer keyboard. There are normally two CTRL keys on your keyboard but they both do the same thing. You can press the CTRL in conjunction with other keys on the keyboard to perform common tasks more quickly. These are known as shortcut key combinations. You hold your finger on the CTRL key whilst you press some other key to perform one of the shortcut actions. Microsoft publishes a list of shortcuts for most of its software. Some of the most common ones are: Ctrl - C to copy Ctrl - S to save Ctrl - X to cut Ctrl - P to print Ctrl - V to paste Ctrl can also be used in Excel to select non-adjacent cells, and to do fills with incremental series.
