1. Give examples of plant responses that are normally associated with animals. In the words of Dr., Hilker “They respond to tactile cues, they recognize different wavelengths of light, they listen to chemical signals, they can even talk through chemical signals. Touch, sight, hearing, speech. These are sensory modalities and abilities we normally think of as only being in animals,” 2. Describe the response of plants to the deposition of insect egg Once a plant has detected an insect, laying…

a) Why do you think is it important to put the bundles of asparagus in water? /1 It is important to put the bundles of asparagus in water. This is because the asparagus will wilt with its water source (the roots) removed. By putting the asparagus’ cut bottoms into water, water will be transported through its vascular tissue systems to the stems and leaves. Then, the asparagus will be able to photosynthesize with the water supply, sunlight, and carbon dioxide, and make food to function. Then,…

3. For this demonstration, we took two bok choy leaves. One leaf we kept the same, the other we removed sixty percent of the leafy area. We placed the leaves in blue dye and let it sit for ten minutes. After, we cut the leaf from the bottom up into one centimeter pieces. Once cut, it was visible that the bok choy leaf that had not been partially removed had more blue dye in the upper petiole compared to the other bok choy leaf. In the bok choy leaf where sixty percent of leafy area had been…

replacing bone and mimicking their structure for, various applications. When looking at biological materials, to determine their effectiveness as a scaffold or sufficient structure for various other uses, often they are tested for their resistance to fracture. This is referred to as fracture propagation. Bamboo Bamboo is well known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it…

chlamydospore are present . Then chlamydospore starts the germination process, thus forming sporangium in which zoospores develop and after some time, zoospores infect the leaves and the bark and the cycle repeats itself. The Pathogen attacks the phloem and the xylem of the plant, which causes the whole decline of the plant by developing canker sores thus yielding bleeding cankers in the process. After a short period of time, the plant experiences a rapid “dead” color all throughout, which…

Symbiosis describes a relationship between species, in which at least one organism benefits. Ants and plants interact in many puzzling ways, but one type of interaction has fascinated ecologists for centuries. Mutualism is a type of symbiosis, where both species benefit from the relationship. Ant to plant mutualisms are facultative, meaning they are not necessary for each other’s survival. However, the survival of both species lends greatly to this complex relationship. (Boucher D.H. 1985) To…

every living cell has water in it. Every living cell in surrounded by fluids. Water dissolves more substances then any other liquid. The ions dissolved in water are needed by organisms for growth and to manufacture various body substances. Every organism must keep it internal body fluids in balance in order to survive. Water uptake must balance water loss. Water- roots and root hair absorb water from the soil by osmosis. Roots are long and have a large surface area. Roots have thousand of root…

Plant Hormones: DIAGRAMS/PICTURES NEEDED: Hormone Locations (color coordinated and showing relative concentrations) Auxin- Auxin is a hormone that’s main function is to promote cell elongation in stems, buds and roots and also plays a small part in the differentiation or new cells. Auxin is present in high concentrations in germinating fruits and seeds, but it is not yet known whether this high concentration of auxin is passed on from the mother or whether is is created but the developing…

The Asian longhorn beetle (anoplophora glabripennis), the Two Spotted Oak Buprestid (Agrilus Biguttatus) and the large pine weevil (hylobius abietis) and Their Relationship to Forests in the United Kingdom Miranda Sanderlin Summary Invasive species of beetle threaten forests in the United Kingdom every year with increasing impact. These beetles cause costly damage, both environmentally and ecologically. The Asian longhorn beetle (anoplophora glabripennis), the Two Spotted Oak Buprestid…

Since 1988 the plant Crupina vulgaris or the Common Crupina has been listed as a class A weed, it has invaded many parts of the Western United States, its has become a growing concern for many as it can grow quickly and is difficult to get rid of. C. vulgaris is native to Mediterranean Europe. It is a flowering plant, or angiosperm from the family Asteraceae, that can grow up to three feet tall. The stems of the plant are leafy and rigid with small spines and rounded 1/2 inch leaves near the…
