<span>DNA stands for deoxyribonucleic
acid. It has a double strand that contains the genes (a hereditary material) of
the organism. It was discovered by James Watson and Francis Crick. Their double-helix
structure was based on x-ray diffraction image named as Photograph 51 or Photo
51. It was taken by Raymond Gosling, a pHD student under the supervision of
Rosalind Franklin. They used this photo to determine the chemical and physical
structure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin</span>
<span>Assume: Energy = Sunlight.
grow lamps, etc.
A is definitely correct: Plants and trees that need maximum light MUST be able to grow as tall or taller than the other plants/trees around them. Plants that are more efficient at producing food (through photosynthesis) can live in the shadows of other plants. B doesnt involve getting or using energy. C is the function of food storage. The Energy was used to make the carbohydrates up in the leaves. D This should read New Leaves on the tree... If the tree was not deciduous, the leaves would stay on the tree and continue to perform photosynthesis throughout the year - as long as there was ample light. A is definitely correct and D is probably a correct answer also. FYI - Photosynthesis takes water from the plant, CO2 from the air and Energy from the Sunlight. Chloroplasts (the Green in the green leaves and stems) combine the molecules and light energy to produce 3 byproducts: O2, H2O, and Carbohydrates (mainly sugar or C12H22O11). The carbohydrates are then transported by the plants capillary system (by means of the Phloem which flows down to the roots) to the roots where it is converted as needed to be stored as some form of sugar or starch for use later in plant growth (leaves, stems and roots).</span>

The function of those tiny root hair cells is to speed up osmosis.
They absorb water and go from the roots to the rest of the plant.
