Answer 2

Explanation:

• like micro chondria chloroplast are also double membrane bound organelles having outer and inner membrane the inner membrane is relative less permeable to substances thatn outer membrane and does has more proteins including carrier proteins space enclosed by the inner membrane of the chloroplast is called as stroma stroma contains a large number of organised flattened membranous sacs called Thylakoids which are arranged in stacks like the piles of coins called gana of the intergranal Thylakoid.1)The thylakoids of diffrent grana are connected by flat membranous tubules called stroma lamellae the membrane of the thylakoids enclosed a space called lumen.2) stoma of the chloroplast contains enzymes required for the synthesis of Carbohydrates and proteins it also contain small double standard circular DNA molecules and 70s ribosomes FUNCTIONS:the chloroplast perform various functions like 1)photosynthesis light reaction in thylakoids dark reaction in stroma 2)storage of starch
