photosynthesis - old stuff that's still good to know

• what is photosynthesis


  The process by which a cell captures energy in sunlight and uses it to synthesise larger organic molecules from simple inorganic molecules
• what is the balanced symbol equation for photosynthesis


  6CO2 + 6H2O -> C6H12O6 + 6O2
• What is the word equation for photosynthesis?


  Carbon dioxide + water -> glucose + oxygen
• what is the main photosynthetic tissue of a leaf


  the palisade mesophyll
• why is the stomata needed


  to allow gas exchange in a leaf
• what substance is used to make an imprint of the stomata to be analyzed


  clear nail polish
• what is the first step to determine the density if the stomata using nail polish


  apply clear nail polish to the lower epidermis of a leaf between the veins and allow it to dry
• what do you do when determining the density of the stomata after you've applied the nail polish and its dried


  using forceps peel the nail polish from the leaf
• why is nail polish used to determine the destiny of stomata on a leaf


  it will create a replica of the lower epidermis
• what happens when determine the density of stomata after the replica has been produce


  place it on a microscope slide and count the stomata
• give 5 adaptations of the leaf for photosynthesis


  large surface area , thin , palisade cells contain many chloroplasts ,air spaces for rapid diffusion and the waxy cuticle is transparent
