Plastids are plant organelles that function in nutrient synthesis and storage. These double-membrane, cytoplasmic structures have their own DNA and replicate independently of the cell. Plastids develop from immature cells calledproplastidsthat mature into chloroplasts, chromoplasts, gerontoplasts, and le...
Amyloplast Function in Plant Cells Lesson Summary Frequently Asked Questions What does the amyloplast do? An amyloplast is an organelle that is only found in plants. It is used to produce, break down, and store starches. What is the amyloplast made of? The organelle is made up of its ...
In vascular plants (ferns and seed plants), proplastids in the meristematic tissues differentiate into several different types of plastid, such as amyloplasts, chromoplasts, etioplasts, and chloroplasts, depending upon which function they need to play in the cell (Lopez-Juez and Pyke, 2005)....
Thus, these data do not support a starch synthetic function for phosphorylase in maize kernels. (c) The quantity of 3-PGA in the starch granule preparation is relatively low and represents only 7% of that in the whole cell. As noted earlier, 3-PGA is an allosteric effector compound which ...

In roots rotated for 15 min parallel to the horizontal axis of the klinostat at 2 rpm, the amyloplasts are not clumped together as densely as in normal, inverted or stimulated roots, but they are not scattered over the entire cell volume. The statolith function of the amyloplasts is ...
The domain of unknown function 490 (DUF490) was found at the C terminus of SSG4, where the ssg4 mutation was located. This suggests that SSG4 is a novel factor that influences the size of SGs and has potential as a molecular ...
creating a continuous network of matrix grids around the SGs; these grids, with SGs capsuled inside, appeared to function as the basic unit of vitreous endosperm formation. One could imagine that the later-formed vitreous endosperm is composed of numerous interconnecting units like this. In contrast...
