You need to understand the structure of the tissues in a leaf together with their functions. The smallest ants, for example, the minims, will ride along on cut sections of leaf while they are carried back to the nest by the media workers. Their outer layer (-epidermis) is thick with cuticle. While hitchhiking, the minims will protect the leaves from parasitic flies and wasps, and work to decontaminate each fragment before it arrives at the nest, while feeding on the sap of the leaf. Few more plant adaptations examples are Temperate Rainforest Adaptation, Taiga Adaptation… They do not need adaptations to conserve water as desert plants. In contrast are the large palmate leaves of Gunnera manicata.On a smaller scale, the shade-loving Hostas, with their lanceolate leaves, mix well with the pinnate-leaved Dryopteris filix-mas (Male fern). Adaptations of the leaf for photosynthesis and gaseous exchange. Vascular tissues are modified accordingly to reduce water loss from the body. The large linear leaves of Phormium tenax (New Zealand Flax) are a well-known striking example. Plants which live in extreme environments have adaptations to control their transpiration rate. The range of leaf forms is described. The kangaroo rat in North American deserts is capable of meeting all its water requirement by internal oxidation of fat (water is a byproduct) in absence of water. and gaseous exchange. This is very important as without these adaptations, algae would grow on the leaves. The leaves in hot or dry environments may be adapted to reduce transpiration. Aquatic plants have floating leaves in which chlorophyll is restricted only on the top surface which is green in color. Consider leaf shape first. It can concentrate its urine, so that minimal volume of water is used to expel excretory products. This tip, along with the waxy covering makes it easier for water to run off the leaves. For example, their stomata. Upper Epidermis: this is the tissue on the upper surface of the leaf. The smaller surface area makes it harder for the leaf to lose water through transpiration. Plant adaptations in the desert, rainforest and tundra allow plants and trees to sustain life. These needle-like leaves have sunken stomata and a smaller surface area, two attributes that aid in reducing water loss. The cactus plant is a good example where the following adaptation can be seen. Tree - Tree - Adaptations: The environmental factors affecting trees are climate, soils, topography, and biota. The leaf is the organ in a plant specially adapted for photosynthesis. The drip tip is the pointed end of the leaf. Most modifications are adaptations to very dry (arid) environments. 2. Leaf Adaptations. Leaf adaptations. may open at night and close at midday. Example of aquatic plants (underwater plants) are water lily, lotus, duckweed, giant Salvinia, etc. Adaptations can include such traits as narrow leaves, waxy surfaces, sharp spines and specialized root systems. For reducing transpiration, the leaves of xerophytic plants have lesser number of stomata, which are sunken and hairy. b. A few examples of adaptations are given below: 1. A good example of this are the pointed leaves of the joshua tree, a species of yucca and a member of the lily family of plants (Liliaceae). Each species of tree adapts to these factors in an integrated way—that is, by evolving specific subpopulations adapted to the constraints of their particular environments. #64 Adaptations of the leaf, stem and root to different environments. Adaptations in Kangaroo Rat: a. Plant populations co-evolve characteristics that are uniquely tailored to their environment. 1. Leaves are adapted for photosynthesis. They are adapted for photosynthesis by … Water plants have no problem of water shortage. Coniferous plant species that thrive in cold environments, such as spruce, fir, and pine, have leaves that are reduced in size and needle-like in appearance. Approximately 90 percent of rainforest plant leaves have what is called a "drip tip."
