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
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
Cell Metabolism Define metabolism, anabolism, and catabolism in full details The cell is a complex organisms in which many chemical reaction take place so as to maintain normal cellular function. Cell metabolism can be defined as the process through which cells manufacture ATP which provides energy to the cells. Cells have evolved to form highly efficient metabolic mechanisms which differ depending on the cell. Aerobic respiration is responsible for cellular energy needs
Cell Junctions - Tight Junctions and Adherens Junctions There are a number of specialized junctional complexes in epithelial cells, formed by molecules that are different from CAMs and SAMs. These comprise of tight junctions, gap junctions, adherens junctions, and desmosomes; gap junctions can in addition form stuck between cell aggregates in condensing mesenchyme. All of these are well-formed and sometimes elaborate supramolecular structures carrying out various functions, ranging from electrical and
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
