An alias type based on a SQL Server system data type. Alias data types are created with the CREATE TYPE statement before they can be used in a table definition. The NULL or NOT NULL assignment for an alias data type can be overridden during the CREATE TABLE statement.
The measure of photochemical efficiency is made by meauring the amount of oxygen produced by leaves following exposure to various wavelengths. It is evident from these absorption and output plots that only the red and blue ends of the visible part of the electromagnetic spectrum are used by plants in photosynthesis.The reflection and transmission of the middle of the spectrum gives the leaves their green visual color.he measured rate of photosynthesis as a function of absorbed wavelength correlates well with the absorption frequencies of chlorophyll a, but makes it evident that there are some other contributors to the absorption.
Written By: Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. The location, importance, and mechanisms of photosynthesis.
