The fluid within a chloroplast

Explanation:

Chloroplasts, the photosynthetic cells in plants, have a membrane, and inside the membrane is a fluid, the stroma. Thylakoids float inside of the stroma in grana stacks and carry out part of the photosynthetic reactions. The rest, the light independant reactions, take place within this fluid stroma.

The colourless fluid present within the chloroplast is called as stroma.

It is an alkaline aqueous fluid that is protein rich and is the location site of chloroplast DNA and chloroplast ribosomes. Molecular processes like chloroplast DNA replication, transcription/translation of few chloroplast proteins all occur in the stroma.

During photosynthesis the Calvin Cycle (biochemical redox reaction) takes place in the stroma. After the thylakoids, the process of producing starch or sugar moves to the stroma. Here simple carbohydrates are formed and this is a light independent process.
