  • Morphology Of The Leaf

    2449 Words  | 10 Pages

    Leaf Morphology: The leaf, in the extensive logic of the period, is extremely veriable in both structure and function. The foliage leaf usually shows it specialization as a photosynthetic organ by the consumed level method of its blade, the lamina. The blade may b attached to the shoot by the petiole, or leaf may b without a petiole if the base of both a sessile or a petiolate leaf encloses the stem, it is reffered to as a sheathing base. Sometime the sheathing part of the leaf is developed into

  • Leaf-cutting Ants

    6329 Words  | 26 Pages

    in North America is the leaf-cutter ant. This is mainly because it lives in tropical environments and it is not aggressive to animals or humans if not disturbed. The leaf cutting ant is a social insect. Alone the ant is virtually helpless but with the colony it can be a thing feared by animal and human alike. The leaf-cutting ants have a very important role in the tropical forest. They create and manipulate the environment around them. They also can do major damage. The leaf-cutting or fungus-growing

  • Stomata Leaf Peel Count

    330 Words  | 2 Pages

    Stomata Leaf Peel Count Aim: · To examine the stomata on the upper and lower epidermis of a leaf. · To investigate and find out which side has more and why. Prediction: I predict that there will be more stomata on the underside of the leaf (the lower epidermis) than on the upper epidermis because that way the maximum amount of sunlight can enter the leaf without many stomata blocking the way. Also, a lower number of stomata would increase the surface area and therefore increase

  • How Light Affects the Stomatal Opening in a Leaf

    1639 Words  | 7 Pages

    How Light Affects the Stomatal Opening in a Leaf Abstract ======== My aim of this investigation was to check the affect of environmental factors affecting stomatal opening. My experiment was designed to check the stomata opening in light. Plants move in ways that may not seem obvious. The opening and closing of stomata is one example of this movement. There are a large amount of growth conditions that can affect a plant. One of the most important of these conditions concerns the

  • Involvement Of K+ In Leaf Movements During Suntracking

    2307 Words  | 10 Pages

    Involvement of K+ in Leaf Movements During Suntracking Introduction Many plants orient their leaves in response to directional light signals. Heliotropic movements, or movements that are affected by the sun, are common among plants belonging to the families Malvaceae, Fabaceae, Nyctaginaceae, and Oxalidaceae. The leaves of many plants, including Crotalaria pallida, exhibit diaheliotropic movement. C. pallida is a woody shrub native to South Africa. Its trifoliate leaves are connected to the petiole

  • Investigating the Relationship Between the Length and Width of a Leaf

    1463 Words  | 6 Pages

    Investigating the Relationship Between the Length and Width of a Leaf Aim: To investigate if there is a relationship between the length and width of the leaves. I will also investigate summary measures to represent my data. Data Collection: I choose to collect my leaves from a tree in my back garden, as it was easy to access. I picked the leaves from different places and different heights around the tree so that my sample of leaves would be random. I choose a sample size of 35 leaves

  • Investigating the Effect of Light Intensity on the Size of a Plantain Leaf

    1322 Words  | 6 Pages

    Investigating the Effect of Light Intensity on the Size of a Plantain Leaf Title: To investigate the effect of light intensity on the size of a plantain leaf. Hypothesis: I predict that the size of the plantain leaves would increase as the light intensity decreases. Therefore, plantain leaves found in the shade will have larger surface areas than leaves found in an open area. Theory: Sunlight is an essential factor need to complete the process of photosynthesis. Photosynthesis consists

  • Investigating Into the Possible Existence of Distribution of Stomata Within Different Leaf Types

    3941 Words  | 16 Pages

    Distribution of Stomata Within Different Leaf Types The aim of my particular experiment was to investigate into the possible existence of distribution of stomata within different leaf types. My investigation also requires me to research into the rate of transpiration into the different leaf types and if this has an effect of the distribution of stomata on the leaves surface. Prediction I predict that the environment of which I found my particular leaf type had an effect on the stomata distribution

  • Papaya Leaf Or Carica Papaya Leaf

    675 Words  | 3 Pages

    has been used in this experiment is papaya leaf or Carica Papaya leaf. The leaf is surface sterilized by placing in a 25 ml of 70% ethanol in a sterile tube and then followed by 10% Clorox that incubate for 2-5 minutes. This is because acidified alcohol is more effective as a disinfectant (Dodds & Roberts, 1990). After that, rinse with sterile distilled water three times. The tools such as forceps and scalpel would be used for all transfers of the leaf. Therefore, forceps tips should be dipped in
