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 about Cells
The main function of the cell body of a neuron is to integrate synaptic information and transmit this information to other cells via the axon. The cell body also completes a variety of biochemical processes to keep the neuron functioning properly.Full Answer >
The main function of muscle cells is to produce contractions of the muscle. Impulses are sent through the nervous system along the muscle cells and cause the muscle to contract.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 >
A lysosome is an organelle in an animal cell that contains enzymes to break down outside materials that enter the cell, as well as obsolete cell material. The lysosome acts as the digestive system for the cell, consuming proteins, carbohydrates and lipids.Full Answer >
