TYPES+OF+PLASTIDS

BIOSTUD PLASTID PAGE. Please include the following information about your plastid: NAME FUNCTION A PICTURE

**Amyloplasts (leucoplasts)**
-are colorless organelles - transform glucose into starch trough polymerization - store starch (amylose) grains, particularly in roots and tubers - found in fruits and some plant cells (ex: potato tubers)  //Amyloplasts in a potato cell// //drawing of an amyloplast//

Chloroplasts that divide and can develop into the other plastids below. 2 Types- Chromoplastids and leucoplastids
 * Proplastid **

=__Chromoplast__=
 * Found in colored parts of plants such as the leaves or the fruit.
 * They convert from chloroplasts
 * Synthesize and hold pigments

__**ETIOPLASTS**__ __**STATOLITS**__ __**LEUCOPLAST**__
 * have not been exposed to light
 * found in angiosperms grown in the dark
 * if chloroplasts are in the dark for a long time they will convert to these (or etioplasts can convert to chloroplasts with lack of light)
 * high concentration of these in plants will make their leaves appear yellowish not green
 * this picture shows a comparison between chloroplast and etioplasts
 * specialized amyloplasts
 * located in a web of actin
 * transmits signals from the web to the root cap
 * is colorless
 * found in cytoplasm of plant cells
 * makes and stores starch
 * mostly present in storage cells of roots and underground stems
 * can change to other types of plastids

*They are believed to store crystalline proteins

 * They are found in many plant seeds

* No recent research has been conducted (25years)
(This was one of the only pictures available, however I'm not sure its correct)

Elaioplasts A type of Lecuplast Specialized storage for lipids in plant cells Holds it in form of Plastoglobuli (This is really the only picture I could find.)
