3. Ribosomes are made up of proteins and ribonucleic acid(RNA)4. It is because of presence of lignin. It is a substance that provides resistance to water entrance, so that the osmotic pressure remains intact within the cell. 5. Softening in young mature fruit, prior to ripening, was associated with a depolymerization of matrix glycans both loosely and tightly attached to cellulose and a loss of Gal from the cell wall fractions, After the initiation of ripening, but before the melting stage, softening was associated with the continuing and progressive depolymerisation of glycans matrix.6. functions of cell wall: 1. Cell wall limit the entry of large molecules that may be toxic to the cell. 2. They permit the creation of stable osmotic environments. 3. Controls cell expansion 4. Controls intercellular transport 5. Protects against infective organisms. 6. It has signalling device against the attack of micro-organism 7. Act as a reservoir of food.
