Lacking photosynthetic pigments, leucoplasts are located in non-photosynthetic tissues of plants, such as roots, bulbs and seeds.They may be specialized for bulk storage of starch, lipid or protein and are then known as amyloplasts, elaioplasts, or proteinoplasts (also called aleuroplasts) respectively.
as external source i used another structure found on the book "molecular cell biology" from james darnell, harvey lodish and david baltimore. i tried to convine all in a complete yet simple diagram. i finish it on the 03-feb-05 —LadyofHats 01:12, 3 Feb 2005 (UTC)" Between the changes made are: removed the leucoplast, under request.
The colorless pigmentation of the leucoplast is due to not containing the structural components of thylakoids unlike what is found in chloroplasts and chromoplasts that gives them their pigmentation. [4] From leucoplasts stems the subtype, proteinoplasts, which contain proteins for storage.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Leucoplast: in algae, the term is used for all unpigmented plastids. Their function differs from the leucoplasts of plants. Apicoplast: the non-photosynthetic plastids of Apicomplexa derived from secondary endosymbiosis.

A diagram showing the different types of plastid. Amyloplasts are thought to play a vital role in gravitropism.Statoliths, a specialized starch-accumulating amyloplast, are denser than cytoplasm, and are able to settle to the bottom of the gravity-sensing cell, called a statocyte. [5]
A librarian at the University of New Brunswick, Lesley Beckett Balcom, recommends the book with reservations, stating, “the sensational illustrations, bold and surreal, are the strength in a book that tries rather too hard to teach a lesson.” [18] An English teacher at Indiana University Northwest believes that A Bad Case of Stripes is “a ...
