Also: 1  All of the members of Blues Traveler, as well as Chris Barron (see above) are from Princeton and were high school friends. 2  All sitting New Jersey governors since 1945 have had their official residence in Princeton, first at Morven and since 1982 at Drumthwacket, but not all have actually lived in these houses.
Concept 4: Structure of a Leaf. Leaves are a plant's main photosynthetic organs. Leaf structure is closely associated with its photosynthetic function. Leaves must permit carbon dioxide access to the photosynthetic cells but impede water from diffusing out.he oxygen that is a waste product of photosynthesis must be allowed to escape from the leaf. Demonstrate your knowledge of leaf structure by placing the labels in their correct locations. NOTE: Answers to questions may be lost when you proceed to the next screen.

The Leaf. Two Functions of the Leaf. 1  Photosynthesis is the process when leaf cells containing chlorophyll take in carbon dioxide and water and using sunlight, make sugar and oxygen. 2  Transpiration is the loss of water from the leaf.3  This helps to draw water up through the plant from the roots. The female part of the flower is the pistil (composed of the stigma, the thin style and the ovary). 2  Pollination occurs when pollen is transferred by insects or wind from the anther to the stigma. 3  Chemicals called enzymes 'drill' a channel down through the style to the ovary where the egg is.
