Question

17. The photo electron micrographs show early and late stages in the development of the cell wall in a young plant cell. early stage lalu sagu cell wall Which statement describes the events lead ng to the development of the cell wall? A Cellulose for the cell wall is synthesised by the Golgi body and modified by enzymes on the cell surface membrane B Erzymes in the cell surface membrane synthesise the cell wall components from monosaccharides brought by the Golgi vesicles C Ribosomes synthesise glycoproteins that are exported by Golgi vesicles to be used in the cell wall D The Golgi body assembles complex carbchydrates into Golgi vesicles that ere exported to the cell well

Answer 1

Plant cell wall sinthesis requires a lot of polysaccharides, they are sinthesized in Golgi and then sent to the cell wall by exocytosis, a special complex here then works with the newly brought elements to form the wall.

The answer then is option A. Cellulose for the cell wall is synthesized byh Golgi body and modified by enzymes on the cell surface membrane
