nucleus?
has nuclear membrane/ envelope with nucleoulus( chromtain)pores so DNA cam come out . has nucleocyptoplsm
mitochondria?
2 membranes folded in a maze shape( christea) for respiration in plant .
golgi apparatus?
synthesis and packages lipids and proteins . trabsorts them around .has lysosomes.
lysosomes?

vacuume
most surface of plant to keep shape and turgidess. weak solution of suger and salts. cell sap
chloroplast
had chlorophyll to absorb light for photosynthesis. has got sacs of thylakoids in packages of granum.
