Plant Cell and Solar Cell: Similarities and Differences
Photosynthesis is that process by which plants harness the solar energy for producing food. These cells help the plants to trap energy from the daylight. This trapped light is converted into other constituents that are then used by the plant to manufacture food. The additional components such as oxygen are released to the atmosphere. After these processes, the light energy is converted to chemical energy. The modern science has been able to develop technologies containing semiconductors that have solar cells. The solar energy is trapped and is converted to electricity by these solar cells (Haile & O'Connell, 2005).
The semiconductors and photosynthesis have some similarities and dissimilarities. As far as the similarities are concerned, their aim is to harness the solar energy. While plants use photosynthesis to lock in energy from the sun for manufacturing food, semiconductors trap solar energy to convert it into electricity (Durham, 2012). It means that the solar cells either...
Plant Cell and describes the structure & function of each part Parts of a Plant Cell: Cell Wall' Protoplast': is bounded by a Cell Membrane and contains Cytoplasm, which consists of: Vacuoles Organelles (consists of Plastids, Mitochondria, Ribosomes, Golgi Apparatus & Endoplasmic Reticulum) Nucleus Structure and Functions of Each Part Cell Wall: The Cell Wall is composed mainly of Cellulose whose molecules are joined together in fibrils as layers and contains openings to make it permeable. Most
The RHDl gene product appears to be necessary for proper initiation of root hairs, whereas the RHDS, RHD3, and RHD4 gene products are required for normal hair elongation. These results demonstrate that root hair development in Arabidopsis is amenable to genetic dissection and should prove to be a useful model system to study the molecular mechanisms governing cell differentiation in plants.(Schiefelbein & Somerville, 1990, p.235) The genetic analysis of root
Meiosis, Transpiration, Monocots, Dicots, Plant Cell, Angiosperms, Fungi, Algae The Events of Meiosis and the Importance of Prophase 1 Generally, meiosis has two divisions of events. Each constitutes 4 phases of same names but of different division number. They are prophase, metaphase, anaphase, and telophase. From Meiosis of Access Excellence, the events in meiosis can be summarized as the following. Prophase 1 - chromosomes duplicate into a pair of chromatid. Later, exchanging of
Enzymes 1. How does temperature affect enzyme function? Every enzyme demonstrates maximum activity at a particular temperature known as its optimum temperature. Generally, all enzymes are inactivated at temperatures below 10°C and get denatured (lose its three-dimensional protein nature) above its optimum temperature (Seager & Slabaugh 2010). Experiments conclude that enzyme activity increases by almost ten percent coupled to each degree rise in temperature until it reaches its optimum state and declines beyond
Cells are known as the basic units of life. One thing that plant cells and solar cells have in common is that they are very important to humans and living things on earth. One main difference between plant cells and solar cells is how each harnesses solar energy. Plants harness solar energy to use photosynthesis. Solar cells harness solar energy to convert it to electricity. One of the main duties of
cells require a layer to separate the inside of the cell from the outside world. Cells have a semi-permiable membrane which controls what can and cannot enter the cell. In animal cells, as well as some others, this membrane is all that separates the cell from its surroundings. Plant cells, and many single-celled organisms such as bacteria have a rigid cell wall beyond the membrane that provides structure. (Buck)
