Light, however, does not guarantee that a proplastid will develop into a chloroplast.
2.
There is no proplastid differentiation when an algal cell divides, its chloroplast divides along with it, and each daughter cell receives a mature chloroplast.
3.
Each nucleoid particle may contain more than 10 copies of the plastid DNA . The proplastid contains a single nucleoid located in the centre of the plastid.
4.
Mg 2 + is probably taken up into chloroplasts to the greatest extent during the light-induced development from proplastid to chloroplast or etioplast to chloroplast.
5.
Whether a proplastid develops into a chloroplast some other kind of plastid is mostly controlled by the nucleus and is largely influenced by the kind of cell it resides in.
