Vegetable oil is........................the phospholipids in vegetable oil have fatty acid tails that ARE BEND.
Vegetable oil are made up of unsaturated fatty acids, which means that double bonds are present in the oil. The degree of unsaturation varies depending on the type of oil. The configuration for double bond is cis; this makes the phospholipid in the vegetable oil to have bent structure.
Inner membrane of the chloroplasts
Explanation:
The present day eukayrotes are all considered to be derived from its original ancestor – the cyanobacteria.
Earlier, photosynthesis by the first photoautotrophs took place utilizing hydrogen sulphide as the electron donor. However, it was later when the cyanobacteria, which were originally residing in the mitochondria of an eukaryotic cell under an endosymbiotic relationship, developed into true chloroplasts, the use of water as electron donor to perform photosynthesis began.
The cyanobacteria were aerobic in nature and required oxygen to survive. They evolved the chloroplasts covered with an external protective membrane and an internal membrane. It is the internal membrane which contains all the necessary organelles or components necessary for photosynthesis like thyllakoids, stroma etc which helped them to utilize water as an electron donor during photosynthesis like all the eukaryotes.
