Tutor description

(Toothman)A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell (in that its electrical characteristics-- e.g. current, voltage, or resistance-- vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source.

It is a form of photoelectric cell (in that its electrical characteristics-- e.g. current, voltage, or resistance-- vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source.Plant cells are eukaryotic cells that differ in several key respects from the cells of other eukaryotic organisms. Plant cells differ from animal cells in lacking:centriolesintermediate filamentsand having:plastidsa cell walllarge vacuolesChloroplasts are the most familiar plastids. They are usually disk-shaped and about 5-8 m in diameter and 2-4 m thick. A typical plant cell has 20-40 of them. Chloroplasts are green because they contain chlorophylls the pigments that harvest the light used in photosynthesis. Chloroplasts are probably the descendants of cyanobacteria tha
