In this article we will discuss about the Subject Matter and Classification of Plastids: Subject Matter of Plastids: Plastids are unique and discrete cytoplasmic organelles found in the cells of most of the plants and certain unicellular organisms particularly protozoa, but not in the cells of higher animals. Although Comparethi (1791) noticed the presence of green granules and Sacks (1865) [...]
The below mentioned article provides a study note on Genetics of Plastids. In the cytoplasm of the plant cells are found many small cytoplasmic bodies, called plastids. These plastids are of several types, such as, chloroplast, leucoplast, chromoplast and so on. Plastids arise from smaller particles, the proplastids, found in the egg cytoplasm. They reproduce themselves independently of other cell [...]
The two important types of Plastids are as follows: The plastids contain the pigments which may be of various types. Sometimes pigments are absent. On the basis of presence of pigments, the plastids are of two types: (i) the chromoplasts (chromatophores) having pigment, and (ii) the leucoplasts which are colourless plastids.
