what would a nucleus of a cell compare to that we deal with each day?
140275
The nucleus of the cell is essentially the control centre. It recieves requests on what materials are needed and it sends out  instructions authorising those materials to be manufactured or acquired.\n\nIn that sense the nucleus is probably most similar to City Hall. It doesn't produce anyhting much besides paperwork, but that paperwork is needed to corordinate everyone else in the city and authorise them to produce real things.

Yeah, It is called oxidation. The cells die and the nuclei become dark, because of the toxic levels in oxygen. Funny how it keeps us alive.

Plant and animal cells are alike in that they both have cell(plasma) membranes, nuclei, and vacuoles. Plant cells are different in that they also contain chloroplasts and cell walls. The vacuoles in plant cells tend to be bigger than in animal cells.

nucleus - \nOne or more per cell \nSpherical shape \nDenser than surrounding cytoplasm\n\nmembrane - \n\nNUCLEAR membrane - Surrounds nucleus\n- Composed of two layers\n- Numerous openings for nuclear traffic\n\nPlasma membrane\n\n- Outer membrane of cell that controls cellular traffic\n- Contains proteins (left, gray) that span through the membrane and allow passage of materials\n- Proteins are surrounded by a phospholipid bi-layer.\n\ncell wall - \n- Most commonly found in plant cells\n- Controls turgity\n\nvacuole - \n\n- Membrane-bound sacs for storage, digestion, and waste removal\n- Contains water solution\n- Contractile vacuoles for water removal (in unicellular organisms)\n\ncytoplasm - \nCollective term for cytosol and organelles contained within \nColloidal suspension \nCytosol mainly composed of water with free-floating molecules \nViscosity constantly changes\n\n\n\n\nEDIT:  Nucleus' job is to be the control center of the cell and also to store the DNA info.

i'd say thats the cytoplasm of the cell

Nucleus contains the genetic material and is where mRNA is produces for later production of protein, which occurs at the rough endoplasmic reticulum.  THe mitochondria carries out respiration, while the chloroplast does the same using light. There are a number of others, of course, but that'll get you started.

Cell membranes and cytoplasm are structures of all cells--both prokaryotic and eukaryotic.  Prokaryotic cells do not have any of the membrane-bound organelles, such as a nucleus, Golgi body, endoplasmic reticulum, etc.

can they? dosent the nucleus control the cells functions? im so confused...

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.

Here's what they have in common:\n1. Cell membrane is present.\n2. Vacuoles are present.\n3. Both are living cells.\n4. Mitochondria is present.\n5. Both are eukaryotic cells. \n6. Nucleus, nuclear membrane and chromatin fibers are present.\n7. Both can reproduce through mitosis. (Advanced animal cells reproduce through meiosis)\n\nPS : Don't take note of those who talk of the absence of mitochondria in plants. It's present. Only chloroplast is absent in animal cell.

animal cells are smaller and more numrous

In animals and plants, cells are the smallest units that can be considered alive. Your body, like all human bodies, is a collection of many many cells. Nearly all cells have the same basic parts - a nucleus, which has DNA, and a cell membrane, which acts as sort of a skin for the cell, keeping insides in, and outsides out. \n\nCells are arranged together to form tissues, which in turn arrange together to form organs, which fit together to form systems (like the digestive system), which in turn all keep you as one functioning living being!\n\nMost cells in a large organism like plants and animals have specialized purposes as well - some are nerve cells, transmitting signals to and from the brain to the rest of the body, some are in your blood, carrying oxygen to the rest of the body, some form your skin, keeping you from getting infected from outside. \n\nCells have their own lifespans, and can reproduce and die.\nSometimes, a mutation happens in cells, and they don't follow their genetic instructions and might grow and reproduce abnormally -- this is what cancer is.

the list of activities is endless:\n\nDNA replication, mitosis, protein synthesis, lipid synthesis, protein and lipid metabolism, oxidative phosphorylation, cholesterol synthesis, and on and on and on the list goes . . . . of course it all depends on the type of cell.

A Bacterium.\n\nCells that lack a membrane-bound nucleus are called prokaryotes (from the Greek meaning before nuclei). These cells have few internal structures that are distinguishable under a microscope. Cells in the monera kingdom such as bacteria and cyanobacteria (also known as blue-green algae) are prokaryotes.
