what is the color of cytoplasm and the nucleus?

Cells are colorless until they are stained. They color that they appear is then based on what type of stain was used. Hope that helps.

eukaryotic cell\n\n        a. Bounded by a nuclear membrane having pores connecting it with the endoplasmic reticulum (see Fig. 1 and Fig. 2).\n        b. Contains one or more paired, linear chromosomes (def) composed of deoxyribonucleic acid (DNA) associated with histone proteins (def)).\n        c. Nucleolus (def) present.\n        d. Nuclear body is called a nucleus (def).\n\n          o Electron micrograph of a nucleus courtesy of Dennis Kunkel's Microscopy\n\n    prokaryotic cell \n\n        a. Not bounded by a nuclear membrane (see Fig. 3).\n        b. Usually contains one circular chromosome (def) composed of deoxyribonucleic acid (DNA) associated with histone-like proteins.\n        c. No nucleolus.\n        d. Nuclear body is called a nucleoid (def).

dunnerzplant pretty much has it right.  To give a more basic explanation, the retina has an array of "rods and cones" laid out like pixels on a tv screen, and they are all connected to the visual cortex that has a similar array of perceptive neurons that can piece all fo the signals together as a picture.\n\nDifferent cells in the retina have different chemicals that are sensitive to different colors, or wavelengths of light.  When light of that color strike that cell, the chemical does a slight shape-shift that ignites a mechanism to change the cell's output of neuroreceptors, liek a switch.  Once the light disappears, the photochemical shifts back to its latent state, and the perception of that color also ceases.\n\nIt's pretty cool stuff, really.  Any good Molecular and Cellular Biology textbook will give a good description of how the whole thing works.  I think even a basic college Biology text will give a rudimentary treatment of the subject.

if ur talking about cells... i think it is organelles...not sure

Elodea leaves are composed of CELLS......that is where the nucleus would be!

Most cells are opaque, or colorless.  If you want a good view, you must color it.

cell wall yes.  chloroplasts no.  cytoplasm in both   i am positive.

The name "white cells" derives the from the fact that after centrifugation of a blood sample, the white cells are found in the Buffy coat, a small fraction between the hematocrit and the blood plasma, which is white in color (or sometimes green, if there are large amounts of neutrophils in the sample, which are high in green myeloperoxidase).\n\nAny of various blood cells that have a nucleus and cytoplasm, separate into a thin white layer when whole blood is centrifuged, and help protect the body from infection and disease. White blood cells include neutrophils, eosinophils, basophils, lymphocytes, and monocytes. Also called leukocyte, white cell, white corpuscle.

A Eukaryote cell is a cell with a nucleus.  A prokaryotic cell is a cell without a nucleus.  Eukaryotic Cells usually refer to the complex cells of multicellular organisms such as animals plants and fungi, whereas many simpler unicellular organisms are made up of the simpler prokaryotic cells.  \n\nA nucleus is the command center of the cell and stores genetic information.  In eukaryotic cells the genetic information is stored in the cytoplasm, or gooey substance that makes up the inside of the cell.

Green \n\nor maybe blue

Mature human RBC have no nucleus.\n\nMuscle cells have several, as a result of cells fusing together.

Egg white are analogous.  It is a mechanical fluid protecting the yolk/cell nucleus.  \n\nIn the cell, the cytoplasm is a sort of warehouse where in-bound nutrients and out-bound wastes are processed and positioned for transit.  \n\nCytoplasm is sort of a bank of protective and equalizing fluids, a kind of checking account, taking deposits from the outside of food and fluids and spending them on the directions of the DNA/RNA and various cell organelles as they call for them.

Look down there..\nThe *.pdf is most detailed and informative.\n\nI am stunned at the total lack of sense displayed by some of these answers! Blood is red! Oxygen poor blood is more 'purpley' in colour but not blue. NONE OF THE BLOOD CIRCULATING INSIDE YOUR BODY IS BLUE!!!

It depends on the what type of cell the nucleus is located in.

Gray matter refers to the portion of the brain that contains a high proportion of neuronal cell bodies, and is thus darker (because of a higher concentration of mitochondria and cellular nuclei), while white matter has a high proportion of axons and dendrites covered with myelin, and is lighter because of the high fat content.  In a living brain, though, gray matter is darkish pink, and white matter is light pink.  It only turns gray and white after being fixed, as in formaldehyde.
