what is?smallest structure in a cell?

the problem to this question is that who will decide the limit of structures, look..!  if you\ntalk about chromosomes then chromatids are also structures similaly genes and then DNA &\nthen centromere & then histone protein........\nat last this discussions come to end at an atom\nbut i still say electrons and protons .........\nso it is difficult :\nanyway i think that ribosomes may be considred as smalles functional alive \norgenelli of the cell

* Anaphase is the shortest phase of mitosis.\n    * The chromatids twins are all pulled apart at the centromere by the spindle fibers, separating as free chromosomes. Each newly separated chromosomes quickly moves to the spindle pole that its microtubule is joined.\n    * The poles of the cell get moved apart. Sister chromatds are pulled to opposite poles by shortening the microtubules joined to them.

The answer to your question is (C). \n\nEvery living organism is made up of one or more cells, all cells arise from preexisting cells, the smallest living organisms are single cells, and cells are the functional units of multicellular organisms.\n\n"Virus - a non cellular parasitic particle that consists of a protein coat surrounding a strand of genetic material; multiplies only within a cell of a living organism (the host)."

Around the cell. It's what holds all the squishy bits in (cytoplasm etc.)

The most obvious (or unobvious) is the centriole found in some nuclei.\n\nMany cells also have ribosomes and vesicles which might be hard to see except under the highest powers.\n\nThe Golgi are also exceedingly small and difficult to see.

Yes.  The term'subcellular" would just mean it is comprised of peices smaller than a cell.\n\nThe term 'components' is simply a word for parts used for assembly.  \n\nMost of these parts are an integral part of the cell, meaning if you get rid of them you lose the cell.

The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life." Some organisms, such as bacteria, are unicellular, consisting of a single cell. Other organisms, such as humans, are multicellular, (humans have an estimated 100 trillion or 1014 cells; a typical cell size is 10 µm, a typical cell mass 1 nanogram).\n\nThe cell theory, first developed in 1839 by Schleiden and Schwann, states that all organisms are composed of one or more cells; all cells come from preexisting cells; all vital functions of an organism occur within cells, and cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.\n\nThe word cell comes from the Latin cella, a small room. The name was chosen by Robert Hooke when he compared the cork cells he saw to the small rooms monks lived in.\n\nAll cells, whether prokaryotic or eukaryotic, have a membrane, which envelopes the cell, separates its interior from its environment, regulates what moves in and out, and maintains the electric potential of the cell. Inside the membrane, a salty cytoplasm takes up most of the cell volume. All cells possess DNA, the hereditary material of genes, and RNA, containing the information necessary to build various proteins such as enzymes, the cell's primary machinery. There are also other kinds of biomolecules in cells.

well i know that a human red blood cell is 10 µm (10 - 30 µm), I'm not sure what a virus is but i think it is significantly smaller.

So lets learn cell structure. We are made of cells. Cells form tissues and tissues form organs and organs form systems and systems make the organism so we are made from cells (Microbes.). Or if you want to be very specific and start from everything before atoms then We are made up of Gluon cells inside atoms.The structure of a cell is a cytoplasm or liquid bag in the center. Cell tissue inside most of it and and a nucleus inside the cytoplasm. I hope sincerely that this answers your question.

Square, with its cell wall?\n\nIt's been a while since undergrad basic biology:-)

An amoeba is the smallest animal in the world. It is a single cell organism. This means it has ONLY one cell in its whole body and insides.

No. \nFirst of all, the endoplasmic reticulum is contained by the cells( except neuronal ones). It's job inside the cell is in the protein metabolic reactions.\nThe microsom is a genetica structure, much smaller than any other components of the cell. It helps transporting genetical information from the reticulum to other structures with the help of genes.

The first and most important thing is for the surface area to volume ratio. The smaller the ratio, the more efficient the cell.\n\nAlso, cells are building blocks of something bigger. If we had huge cells, imagine how big we'd have to be in order to hold trillions of them. ;)\n\nThat's about it in the nutshell.

all cells are composed of atoms in the nucleous.  All cells have a cell wall/cell membrane, cytoplasm/protoplasm.\ngolgi bodies\n\n\nYou can't have a cell without these things

An animal cell is a form of eukaryotic cell which make up many tissues in animals. The animal cell is distinct from other eukaryotes, most notably plant cells, as they lack cell walls and chloroplasts, and they have smaller vacuoles. Due to the lack of a rigid cell wall, animal cells appear to be circular (though are often deformed by surrounding cells) under microscopes - in three dimensions the cells are normally spherical.

The cell is still made up of many atoms, thats the only irrefutable link there. And the atom is not the elementary essential of matter, if by elementary essential you are referring to the smallest constituent of a matter. Atom is made of of sub-particles: protons, electrons, neutrons, quarks... And these are further made up of smaller sub-particles (our knowledge are always limited). Proton and nuetron have masses and volumes. Doesnt that mean they are matter too?
