The shape of a cell dictates the function of that cell. This is more pertinent to animal cells that, unlike plant cells, do not have a rigid cell wall. A misshapen cell cannot properly perform its intended function.Know More
Cells are the essential building blocks of all living things. Neurons are a prime example of a cell with a specific shape that perform a single but vital function. They are long and thin with many branches. They have a very distinctive appearance with a long, trailing axon with branches at the end and a neuron surrounded by branching dendrites. Their function is to carry electrical signals to and from the body and the brain.
Size as well as shape plays a crucial role in cell function. A cell must be big enough to contain all the essentials, which include DNA strands, protein, and survival and reproductive structures. However, the cell must be small enough to have a large enough surface area in relation to volume to absorb enough nutrients to support its functions and to dispose of waste products. Larger cells have a larger surface area. However, large cells have less surface area in relation to volume than their smaller counterparts.Learn more in Cells
The function of a galvanic cell is to produce electricity through an oxidation-reduction reaction. Galvanic cells are used in batteries to convert chemical energy to electrical energy. Another name for a galvanic cell is a voltaic cell.Full Answer >
Pollen grains carry the sexual cells of plants from one flower to another. According to Pacific Union College, plants produce cells that give rise to pollen in each of four pollen sacs residing on each of the flower's anthers. Each pollen-producing cell divides, producing four discrete pollen grains. The sperm cells found in the pollen fertilize the ova found in female flowers, initiating development of the new plant.Full Answer >
According to the dictionary at Biology-Online.org, cellular irritability describes the ability of any cell to recognize and react to stimuli in its immediate surroundings. In a pathological sense, this recognition ability is under-regulated, which results in excessive amounts of the body's sensitivity to certain stimuli.Full Answer >
The function of an onion cell is to organize the biological processes of an onion. The onion, like other complex organisms, has different cells. There are cells that make up its leaves and flowers, cells that make up the onion bulb and cells that make up its roots.Full Answer >
