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.
English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series. Cytoplasm; Nucleus; Cell membrane; Mitochondrion ...
[1] [2] Plastids perform a variety of functions such as metabolism of energy, and biological reactions. [2] [3] There are multiple types of plastids recognized including Leucoplasts, Chromoplasts, and Chloroplasts. [2] Plastids are broken up into different categories based on characteristics such as size, function and physical traits. [2]
The primary endosymbiotic event of the Archaeplastida is hypothesized to have occurred around 1.5 billion years ago [26] and enabled eukaryotes to carry out oxygenic photosynthesis. [27] Three evolutionary lineages in the Archaeplastida have since emerged in which the plastids are named differently: chloroplasts in green algae and/or plants ...
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]

In 1903, Nikolai K. Koltsov proposed that the shape of cells was determined by a network of tubules that he termed the cytoskeleton. The concept of a protein mosaic that dynamically coordinated cytoplasmic biochemistry was proposed by Rudolph Peters in 1929 [12] while the term (cytosquelette, in French) was first introduced by French embryologist Paul Wintrebert in 1931.
