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.Know More
The type of onion cell in the plant is determined by the proteins the cell produces. As in most living things, the onion's DNA creates the blueprint for all the proteins the plant produces.
As a plant cell, the onion cell is different from the cell of an animal. For one thing, it has a cell wall that surrounds the cell membrane, which an animal cell lacks. At least some kinds of onion cells have chloroplasts, which is where photosynthesis takes place. Photosynthesis creates fuel for the plant.
An onion cell also has mitochondria, which are the power plants for the cell. Onion cells also have nuclei, which contains proteins, DNA and nucleoli. There are also Golgi bodies, which are flat bodies that prepare carbohydrates and proteins to be exported out of the cell. There are large, watery spaces called vacuoles and ribosomes. Ribosomes contain RNA, which copy the blueprints of proteins made by the DNA. Everything floats in a jelly-like substance called cytoplasm.Learn more about Cells
In a typical onion cell lab, students observe the structure of onion cells using a microscope. Students usually complete the lab using both low-power and high-power magnification.Full Answer >
The length of a typical onion epidermis cell is between 0.25 and 0.40 millimeters. These cells are in the top layer of tissue that covers an onion. Unlike most plant cells, onion epidermis cells have no chlorophyll.Full Answer >
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 >
The two main functions of a muscle cell are to produce movement through force and to maintain posture, according to Science360. They are frequently called muscle fibers because the length of a muscle cell is greater than the width.Full Answer >
