AMYLOPLASTID Meaning and
Definition
-
Amyloplastid is a specialized type of plastid found in plant cells, responsible for the synthesis and storage of starch. These organelles are non-pigmented and appear colorless under a microscope. The term "amyloplastid" is derived from "amylum," which refers to starch, and "plastid," meaning a double-membraned organelle in plant cells.
Amyloplastids primarily occur in storage tissues such as roots, tubers, seeds, and fruits, where they fulfill the vital role of starch production and storage. They are involved in converting excess carbohydrates and glucose synthesized during photosynthesis into starch molecules. During this process, they use enzymes like amylose synthase and granule-bound starch synthase to create long chains of glucose molecules that form starch granules. These granules are then stored within the amyloplastid until needed.
The shape and size of amyloplastids can vary based on their location within cells and the plant species. They typically exhibit a spheroidal or ellipsoidal shape and possess a single large central vacuole surrounded by layers of starch granules. Additionally, amyloplastids may contain small lipid droplets and a limited number of mitochondria.
In summary, amyloplastids are double-membraned organelles specializing in the synthesis and storage of starch in plant cells. They play a crucial role in plant metabolism and energy storage, contributing to the formation and accumulation of starch granules in various plant tissues.

Etymology of AMYLOPLASTID
The word "amyloplastid" is derived from two main components: "amyl/o" and "plastid".
The term "amylo-" originates from the Greek word "amylon", which means "starch". "Amylon" is derived from the Greek word "amylē", which means "fine meal" or "starch". In biology, "amylo-" is commonly associated with substances related to starch or carbohydrate storage.
The suffix "-plastid" comes from the Greek word "plastos", meaning "molded" or "formed". This root is also used in words like "plastic" and "plaster". In biology, "-plastid" refers to structures found in the cells of plants and algae, involved in various functions such as photosynthesis, storage, and pigmentation.
