open and close in response to their environment. We were given the choice to test either the null hypothesis or the alternate hypothesis. The null hypothesis proposed that there is no difference between stomatal density of a young and mature hibiscus leaf. Conversely, the alternate hypothesis hypothesized that there is a difference between stomatal densities in young and mature hibiscus leaves. I chose to test the alternate hypothesis because I thought a young plant with a higher density of…

BIOLOGYOF TARO LEAF BLIGHT (Phytophthora colocasiae Racib) - A REVIEW ABSTRACT Taro is a tropical tuber crop highly valued in developing countries. It is mostly susceptible to Phytophthora colocasiae, a leaf blight disease (TLB) causing a 25%-50% loss in yield. The pathogen results not only in reduction in vigor, quality and yield but also constitute a barrier to international exchange of germplasm. The warm, humid days, cool and wet nights of the tropics are ideal for reproduction and…

Papaya leaf is one of the vegetables taken from the leaves on plants or fruit trees. Indonesians eat papaya leaves as lalab or leaf cooked in a processed way as snacks for cooking rice and also other side dishes. Uniquely papaya leaves have a different taste with the fruit that bitter. But the bitter taste does not limit many Indonesian people to like the leaves of papaya. Even if you can process it, then the leaf will not be too bitter. Behind the bitter taste, it turns out papaya leaves store…

of the different colored pigments in the leaf to identify the different pigments. For example, when looking at a normal leaf, you only see that it is green because chlorophyll a and chlorophyll b are the most abundant in green leaves because those chlorophyll’s pigment is green, and as a result we do not see any other pigments just by observing with the human eye. Thus, we use paper chromatography because the chromatography paper separates the different leaf pigments based on their solubility.…

Let them who have an ear; hear; Yet see how this leaf wonders. Is it a bird? Is it a plane? No,…

Flags have symbolized and represented countries for hundreds of years. Canada has had multiple flag changes since Confederation from the Union Jack to the Red Ensign. However, a new flag was announced and has been Canada’s flag ever since. Creator of the peacekeepers and future Prime Minister Lester Pearson had successfully convinced Canadians that Canada was in need of a brand new flag. That flag has changed Canada’s identity as an independent nation by removing British influences and uniting…

Discussion Leaf number, leaf area, plant height and plant spread: The effects of different levels of water stress on the growth parameters like leaf number, leaf area, plant height and plant spread of S. aethiopicum was recorded maximum in the plants grown at 100% PC. Treatments T1 and T2 (75% PC and 50% PC) did not show the significant difference, though there was drastic reduction in growth at 25% PC. Highest recording of all the parameters in 100% PC probably attributed to the optimum supply…

mechanism) is very rough and is always green. This part of the organism’s body is also covered with a fragrant nectar that attracts its prey towards it. When the prey reaches the Venus flytrap, it begins to feed off of the nectar. Once touching its leaf, the prey sets off a twenty second timer. After the time is up the two leaves close together, trapping its prey into their holdings. Although there is a way that the prey’s last few seconds alive may be shortened. This could only happen if the…

they should stick with half-and-half. Based on research, one may determine that the Nissan LEAF is is the better option as far as economics goes, but the Prius exceeds in performance. First, the 2015 Nissan LEAF may be priced as low as $21,510, but could rise up to nearly $30,000 (“Nissan LEAF®”). On the other hand, the 2015 Toyota Prius prices around $24,000, which is very close to the prices of the LEAF (“2015 Prius”). With only this data, it is nearly impossible to say which is better because…

This disagreement was about the pigments located in the stems and veins of a plant and the pigments located in the green portion of a leaf. Jan believed that only the stems and veins contained all of the important pigments except for chlorophyll. She believed that the green portion of the leaf would not contain all these other pigments. Mark, on the other hand, believed that the same pigments were also located in the green portion even though they were not visible. In order to determine who was…
