The structures that make up a cell are called

Within cells, the cytoplasm is made up of a jelly-like fluid, called the cytosol, and other structures that surround the nucleus. Cytoskeleton. The cytoskeleton is a network of long fibers that make up the cell's structural framework

cytoskeleton is the correct answer

there are plastid colour pigment organelle containing a verity of colours

              plastids contain of three organelles 1) chloroplast   (2)   chromoplast   (3)   lecoplast

            the verities of colours are present in chromoplast rather than green so, petals of sun flavour colour is due to chromoplast.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
