Why the cell have the circle of our  life; The origin of cells has to do with the origin of life,
Without cell cycles, there would be no life on earth. Cell cycles, which typically form two "daughter" cells out of a parent...
What is the function of cell wall?The cell wall is the structural part of the cell that is unique to plants. It is the structure that is present immediately adjacent to the cell membrane.In plants, the cell wall is made up mostly of cellulose, determines tissue texture, and often is crucial to cell function.The function of a cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. They are usually found in bacteria, plants, algae and fungi amongst other organisms. more info here
Why the DNA produce RNA?The process of making an RNA strand from a DNA copy is called transcription.
Information from the DNA has to be transmitted to the cytoplasm from the nucleus.The DNA is too large to move through the nuclear membrane, it must make a replication of itself.
A difference between RNA and DNA is that RNA uses Uracil instead of Thymine.

Why the RNA produce protiens?
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other ... RNA (tRNA) assembles the protein, ...
The rna leaves the nuclear membrane towards the cytoplasm. It is in the cytoplasm where the rns gets binded to a ribosome for the synthesis of proteins. The ribosome and rna bind and bring in tRNA proteins that hold the building blocks for the construction of a brand new protein which will be synthesized according to the data provided on the RNA itself. Ultimately the goal of the RNA is to be used for protein synthesis. There are 3 ribosomal regions that hold the incoming tRNA while the ribosome reads the RNA. The first brings in the tRNA. The second region transfers the peptide piece tRNA is carrying to another tRNA that is linking the peptide together. The last slot releases tRNA proteins that have given up their peptide piece that they had with them when going into the ribosome itself.

Why the cell wall is non living?The cell wall is a tough, flexible but sometimes fairly rigid layer that surrounds some types of cells. ... It is the non- living component of cell..
The cell wall acts to protect the cell mechanically
A cell wall supports membrane , gives it a shape and protects it but, ... Why is the cell wall non living? Because it has no bioligical function,The first seen cell was non-living. It was founded by Robert Hooke in 1665 in a piece of cork.

Why the pores of cell wall called plasmodesmata?
plasmodesmata's examples
Fine strands of cytoplasm, called plasmodesmata, extend through pores in the cell wall connecting the cytoplasm of each cell with that of its Plasmodesmata provide an easy route for the movement of ions, small molecules like sugars and amino acids, and even macromolecules like RNA and. — “Junctions Between Cells”,
All this strongly suggests that plasmodesmata are contractile "organelles" that fluctuate between these three structural states and that actomyosin- and centrin-based forces are in a position to participate in the gating of plasmodesmata via calcium-sensitive pathways. — “Sink Plasmodesmata as Gateways for Phloem Unloading. Myosin”,
Plasmodesmata are "cytoplasmic bridges" through the cell wall connecting the cytoplasm of adjacent plant cells. The cell membrane lines the pores and therefore does not separate the adjacent cells. What do you think is the function of plasmodesmata, and why are they necessary?. — “Plasmodesmata”,

Why the Cytoplasm is the semi viscous and semi transparent substance between pasma membrane and nucleis envelope?
The term cytoplasm can be used to describe the matrix of a cell found between its plasma membrane and the nucleus. It encloses various cell organelles and inclusions.

The cytoplasm is a semi viscous jelly-like substance. It consists of an aqueous, almost transparent structureless ground substance called hyaloplasm or cytosol. Nearly 90% of cytosol is water. It also contains the various biomolecules, both micromolecules and macromolecules. All those substances occur in the cytoplasm in a state of solution.

It is called the cytoplasm. It is a jelly-like material that is eighty percent water and usually clear in color. It is more like a viscous (thick) gel than a watery substance, but it liquefies when shaken or stirred. Cytoplasm, which can also be referred to as cytosol, means cell substance. This name is very fitting because cytoplasm is the substance of life that serves as a molecular soup in which all of the cell's organelles are suspended and held together by a fatty membrane. The cytoplasm is found inside the cell membrane, surrounding the nuclear envelope and the cytoplasmic organelles.

The cytoplasm, as seen through an electron microscope, appears as a three-dimensional lattice of thin protein-rich strands. These lattices are known as microtrabecular lattice (MTL) and serves to interconnect and support the other "solid" structures in the cytoplasm. In other words, the cytoplasm is like a fence that is made up of lattes that are connected together. This fence's main purpose is to hold together the organelles within the cytoplasm.

Cytoplasm is the home of the cytoskeleton, a network of cytoplasmic filaments that are responsible for the movement of the cell and give the cell its shape. The cytoplasm contains dissolved nutrients and helps dissolve waste products. The cytoplasm helps materials move around the cell by moving and churning through a process called cytoplasmic streaming. The nucleus often flows with the cytoplasm changing the shape as it moves. The cytoplasm contains many salts and is an excellent conductor of electricity, which therefore creates a medium for the vesicles, or mechanics of the cell. The function of the cytoplasm and the organelles which sit in it, are critical the cell's survival.

What is plasma membrane?The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside
All living cells have a plasma membrane that encloses their contents.
Answer:The plasma membrane, is the thin, outermost membrane that separates each cell from its outside environment. The membrane lets internal metabolic reactions proceed in controllable ways, but does not isolate the cell interior. Water and gases cross in and out freely, but the flow of other substances across the membrane is controlled. Membranous protective covering of the cell.

The plasma membrane is the membrane surrounding a cell that separates the cell from its external environment - responsible for barrier function; consists of a phospholipid bilayer (polar head group, nonpolar tails) and associated membrane lipids and proteins (integral-help transport hydrophilic molecules across bilayer, peripheral, and lipid-anchored proteins).

The plasma membrane (cell membrane) is made of two layers of phospholipids. The membrane has many proteins embedded in it.

The plasma membrane regulates what enters and leaves the cell. Many molecules cross the cell membrane by diffusion and osmosis.
