plasma or cell membrance   size:"Membranes are typically 7.5–10 nm in thickness with two regular layers of lipid. Description :  The plasma membrane is a fluid mosaic. ... Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell  Function :

The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

where:cell membranes are found between the cell wall and cytoplasm, the gel-like fluid within a cell. Plant cell membranes serve two major functions. First, along with the cell wall, the membrane helps provide structure.

cell wall size The gram positive cell wall is usually between 20 and 80 nm thick while the gram negative cell wall is usually between 5 and 10 nm thick. The cell wall forms a boundary around the cell, to support and protect the cell.   structure A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. ... In bacteria, the cell wall is composed of peptidoglycan.  function  

The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell   where A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.

nucleous  size  The nucleus is the largest organelle in animal cells. In mammalian cells, the average diameter of the nucleus is approximately 6 micrometres (µm), which occupies about 10% of the total cell volume.

description The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.   function it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).  where is located in the central region of the cell. In a plant cell, the nucleus is located more on the periphery due to the large water-filled vacuole in the center of the cell.

i'm sorry i couldnt finish this is alot i see why you aked us to help you
