hydroelectric power plant diagram. Water reservoir: In a reservoir the water collected from the catchment area during the rainy season is stored behind a dam. Catchment area gets its water from rains and streams. Continuous availability of water is a basic necessity for a hydroelectric power plant. The level of the water surface in the ...
In plant cells, the first part of mitosis is the same as in animal cells. (Interphase, Prophase, Metaphase, Anaphase, Telophase). Then, where an animal cell would go through cytokineses, a plant cell simply creates a new cell plate in the middle, creating two new cells. The cell plate later changes to a cell wall once the division is complete.
A typical plant cell is around 10 to 100 micrometers in diameter, while a bacterial cell is usually between 0.5 and 5 micrometers. Cell Wall: Both plant and bacterial cells have cell walls, but their chemical composition is different. Plant cell walls contain cellulose, while bacterial cell walls use peptidoglycan.

The release of Zn 2+ from the commercial lithopone pigment was fast and extensive under natural conditions, with 35.16% Zn released within 6-h solar exposure. …
Broadly, plants have two organ systems: A) the root system and B) the shoot system. A typical diagram of a plant body consists of three parts: 1) roots, 2) stems, and 3) leaves, each having specialized functions.Apart from these basic parts, a flowering plant also contains 4) flowers and 5) fruits.. The root system covers the underground parts of …
lithopone, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. Lithopone was developed in the 1870s as a substitute or supplement for lead carbonate (), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds.Lithopone is an insoluble mixture of barium …
