Intro to molecular biology8 march 23 2017. The living cell slide 1: to propagate/profiliferate replicate itself, to ensure survival, to harvest energy, to ensure that all products are utilized most efficiently. Plastid that can be molded" flexible. The presence of a double membrane envelope. Plastid stroma filled extensions are called stromules. Photosynthetic machinery on a system of flattened membrane scas thylakoids. Outside the thylakoid but inside inner envelope is the stroma. Several hundred chlorophyll molecules act together as one photosynthetic unit. The antenna system harvests light of various wavelengths and transfers excitation energy to the reaction center. Photosynthesis consists of light dependent and light independent (dark) reactions. Solar energy absorbed and stores in atp (cell"s primary source of chemical energy) and. Carbohydrate synthesized from co2 using energy from atp/nadph. Proteins and lipids are exchanged between plastids and the er. Plastids have their own dna and ribosomes but are also controlled by nuclear encoded proteins.
