Q5 which substance is responsible for transfer of characters from one generation to another?
Q6 Differenciate between a)Plant and Animal b) Diffusion and Osmosis

Answer 1

1 chloroplasts r found in plastids of plants
2 it influences the distribution of nutrients and other matter.it also acts like a filter and stops undissolved solids to enter body
3 genes r located in chromosomes which r in our DNA(deoxyribonucleic acid)
4 robert hooke-discovered cells
   leeuwenhoek-improved the primitive microscope & observed free living cells in pond water
   robert brown-discovered nucleus in the cells
5 genes r responsible for tranfer of characters from one generation to another
6 plants- they hv plastids 
              plant cell has cell wall
               they perform photosynthesis
               plant cell has a huge vacuole
 animals- they dont hv plastids 
                animal cell doesnt hv cell wall
                they do not perform photosynthesis
               animal cell has small vacuoles


diffusion- when a gas with high concentration in a region moves out to a low concentration region in a cell
osmosis -it is similar to diffusion but instead of gas it is water molecule 
so movement of water molecules from high concentration area to low
