what do simple cuboidal cells do?
816419
Most of the time, simple cuboidal epithelium is what makes up glands or secretory tissues like what you would find in your tear ducts or sebacious glands (sweat glands).  They are also found surrounding female ovaries and the thyroid gland, not to mention the very important components of the kidneys (nephrons).

squamous cells: function primarily in alveolar gas exchange and fluid balance. \ncuboidal cells: responsible for pulmonary surfactant secretion and metabolism.

"Many nerve cells are of the basic type illustrated above. Some kind of stimulus triggers an electric discharge of the cell which is analogous to the discharge of a capacitor. This produces an electrical pulse on the order of 50-70 millivolts called an action potential. The electrical impulse propagates down the fiber-like extension of the nerve cell (the axon). The speed of transmission depends upon the size of the fiber, but is on the order of tens of meters per second - not the speed of light transmission that occurs with electrical signals on wires. Once the signal reaches the axon terminal bundle, it may be transmitted to a neighboring nerve cell with the action of a chemical neurotransmitter.

A thin flat cell will diffuse faster than a cube shaped cell.\n\nIt all depends on it's surface area to volume ratio. The higher the ratio is, the higher the rate of diffusion.

from original cell 2 from those (daughter cells)  they each split again which results in 4 cells...hope this helps...the question is hard to understand

Yep.  Just make sure you use the correct primitive cell (not necessarily unit...) and it'll behave.

there are 3 basic kinds-epithelial cell shapes and they all vary in their dimensions. Which one are you needing?  Also cell size varies somewhat depending on the organism you find the epithelium in, whether it be one species or several species.\n\nsquamous?\ncuboidal?\ncolumnar?\n\ncolumnar are biggest, squamous are thinnest. Cuboidal are probably the smallest on the average.

1."If the cell is disturbed, one can observe the discharge of the outer coating of trichocysts. These spine-like structures, analogous to nematocysts (the stinging cells of jellyfish), can fire out from the cell in a fraction of a second at the slightest physical or chemical stimulus. Discharged trichocysts may remain attached at their base; until they detach, the cell resembles a disheveled porcupine. The exact function of trichocysts is not known but it is thought they may be used for capturing prey"\n\n1."Upon mechanical or chemical stimulation, these trichocysts can be discharged (as shown on the model) to produce long, sticky protein threads that remain attached to the organism.  It is believed that these structures can be used for defense."\n\n\n2."The paramecium moves by swimming. For the paramecium to move forward the cilia beat on an angle, backward. This means that the paramecium moves by spiralling through the water on an invisible axis. For the paramecium to move backward, the cilia simply beat forward on an angle. If the paramecium should run into a solid object the cilia change direction and beat forward, causing the paramecium to go backward. The paramecium turns slightly and goes forward again. If it runs into the solid object again it will repeat this process until it can get past the object. "

It's not to do so much with the useful function; rather how the symetry arises. Each organisn arises from a single cell. The clump of cells becomes a ball, that then flatens out and develops a neural tube (becoming the spine and brain complex). From that, everything fans out. as the neural tube forms by a symetrical folding, so all things from it are symetrical as a mirror image forms or each part.

Cuboid is a 3D rectangle\n\nExamples in home are:\nComputer midi towers\nwardrobes\nNew fashion coffee tables\nMicrowaves\nOven\nFridge\netc..\n\nAnything that is a cube is also a cuboid as a cube is a special cuboid where all the sides are equal

The cells are usually designed for its purpose for the body. For example, your red blood cells doesn't have several key organelles that other cells have (sorry I forgot the organelles) because they have a short life span. Throughout biology, there is a recurring theme that the form of an organism usually fits its function. That’s why the cell's shape usually fits its function. Also, natural selection favors those with superior qualities.

a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice. The spacing between unit cells in various directions is called its lattice parameters. The symmetry properties of the crystal are embodied in its space group. A crystal's structure and symmetry play a role in determining many of its properties, such as cleavage, electronic band structure, and optical properties.\n\n\nThe crystal structure of a material is often discussed in terms of its unit cell. The unit cell is a spatial arrangement of atoms which is tiled in three-dimensional space to describe the crystal. The unit cell is given by its lattice parameters, the length of the cell edges and the angles between them, while the positions of the atoms inside the unit cell are described by the set of atomic positions (xi,yi,zi) measured from a lattice point.\n\nFor each crystal structure there is a conventional unit cell, which is the smallest unit that has the full symmetry of the crystal (see below). However, the conventional unit cell is not always the smallest possible choice. A primitive unit cell of a particular crystal structure is the smallest possible unit cell one can construct such that, when tiled, it completely fills space. This primitive unit cell does not, however, display all the symmetries inherent in the crystal. A Wigner-Seitz cell is a particular kind of primitive cell which has the same symmetry as the lattice.\n\n\nfor further clarifications go to the site listed

False, its the other way round.\nSingle celled orgarnisms have only one cell. this cell has different components that help it become multi-funtional. this means that its single cell are not specialised. for example. an Amoeaba which is a single celled organism has a nuclei which it uses for its metabolic processes, its mitochondria for energy, its cell wall for movement. so this one cell of an amoeba can perform different functions.\n\nmulti cellular ogarnisms have different cells that have been specialised for different purposes. e.g respiratory cells are for metabolic processes, growth cells are for growth, digestive cells are for digestion. \n\nthe digestive cells in a multicellular organisn come together to form digestive tissues. the digestive tissues will come together to form a digestive organ, different digestive organs will form the digestive system. different systems form the body.\n\nthanks. chaoo

Unfortunately there isnt any average cell-as said before, there is variation from minutes, in the case of some immune and germ cells, to never in the case of most neurons.  But, to give you a way to answer your homework, you can say a hypothetical cell takes 24 hours to divide-there are quite a few cell types that take about this long, so you would be safe choosing this time.

To make it easier to understand, if you had a gigantic cell that was shaped like a perfect cube one inch on a side, if it grew to two inches on a side the surface area would increase from six square inches to sixteen square inches. The volume would increase from one cubic inch to eight cubic inches.
