Leaf node

First we obtained a leaf from our instructor. Then we sketched the leaf and labeled the blade and petiole. The following procedure dealt with a chromatogram. The materials needed are: a pencil, safety goggles, scissors, chromatography paper strip, capillary tube, spinach plant pigment extract

Our lab investigated the morphological characteristics of leaves found in the sun and shade on various species of maple and oak trees around campus. Our null hypothesis was Acer and Quercus acclimate similarly with regards to SLW (specific leaf weight), size, and sinuosity. Our hypothesis was Quercus acclimation is greater than Acer SLW, size, and sinuosity. We tested these hypotheses by picking small sections of a branches from both maple and oak trees. A group was assigned either a maple or an

“Wake up, put shoes on and come downstairs to eat,” my grandmother says as she's opening the curtains in my room. As she walks out the room, she turns around and says “Do you want tortillas with your chorizo and frijoles so I can heat a couple up.” Even though she leaves the room without my answer, in her head, already knowing my answer. I put on a pair of jeans and walk downstairs into the dining room, there was a plate with frijoles, chorizo and tortillas waiting for me. My grandmother brings

Titles and Authors: Transpiration Lab Report By: Ashley Learned, Emma Grau, Grace Krier Abstract: The purpose of this experiment was to evaluate the effect of varying environmental factors on the rate of transpiration. We decided to test the factor of light, and what the rate of transpiration is before and after taking away sunlight. We found that the rate of this process was relatively the same in both the light and the dark areas of the classroom. Discussion: In our lab, we tested our question

Ronnie Estes Rocky Mountain Flora April 17, 2015 Timothy Family/Description Timothy, Phleum pratense, is in the family Poaceae, the grass family. This grass is a cool-season perennial plant that grows in bunches or clumps. It has a shallow and fibrous root system. Leaves vary in length from a few inches to a foot and are about 1/4 inch wide and narrowing toward the tip. Heads are a dense cylindrical spike-like panicle. Seeds are very small, numerous and usually enclosed in glumes. Timothy is

Marin Dwarf Flax (Hesperolinon Congestum) Hesperolinon Congestum is among the Linaceae family. It is categorized to be an annual Herb but also considered wildflower. Normally their leaves are not planar but linear. Their flowers are mostly congested in clusters, with slender stems that are 4-6 inches long. These flowers only grow in San Mateo, San Francisco, Marin County, California, and United State. Marin Dwarf Flax often occurs on serpentine soils, in dry native bunch grasses, chaparral or

Banksia coccinea, commonly known as the scarlet banksia, waratah banksia or Albany banksia, is an erect shrub or small tree in the family Proteaceae. It grows only along the south west coast of Western Australia, from Denmark to the Stokes National Park, and north to the Stirling Range, growing on white or grey sand in shrubland, heath or open woodland. Reaching up to 8 m (26 ft) in height, it is a single-stemmed plant that has oblong leaves, which are 3–9 cm (1.2–3.5 in) long and 2–7 cm (0.8–2.8

Paradisiacal normalis, M. sapien-tum and M. cavendishi as well as the length, width, and thickness of the leaf and the number, diameter, and tensile strength of leaf fibers. Samples were collected in Dampit, Wajak and Batu, Malang, Indonesia. Microscope slides used for anatomical observations were pre-pared using a semi-permanent method. The Retting method was applied to extract the

dependent variable was stomata density, and the independent variable was sunlight (sun and shade). The stomata impressions were made by using the nail polish to inscribe the stomata on the leaves bottom. The imprint was applied in the calculation of leaf stomata density. A t-test was used to compare the results between two variables (sun and shade). A significant difference of stomata density was observed between the leaves in the sun and shade. The leaves in the sun had the highest stomata density

Memory. Age 6. A pool near my house stays open all year round. Even when snows falls to the ground, the water remains in the pool. When the water freezes over and kids dare each other to walk across the ice. I’ve never done it, but the older boys who my brother wants to be just like all took the challenge at least once. I sit on the grass near the pool. Once, they built fence around the water, but they took it down one year for “cleaning”; no one knows what happened to the fence after that. I
