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.

This process occurs in almost all plant species and is carried out in specialized organelles known as chloroplasts. All of the green structures in plants, including stems and unripened fruit, contain chloroplasts, but the majority of photosynthesis activity in most plants occurs in the leaves. On the average, the chloroplast density on the surface of a leaf is about one-half million per square millimeter.
