Auxin

In order to exam the effects of auxin, gibberellins and abscisic acid on plant growth we generated an experiment to track the growth, specifically height of a corn seed. To begin, obtain two small planters, each with six individual compartments. Label one planter A and the other B. On the outside of the two small planters label five of the six compartments IAA, NAA, GA, ABA, and Control. The sixth compartment will not be used. These labels respectively correspond to the hormone treatment that…

This is relevant question for the life of plants because cytokinins primarily promote lateral growth (branching out), balanced by auxins (a different plant growth hormone) which combat lateral growth. It is crucial for germination because the endosperm of the seeds contain large amounts of the cytokinin (specifically zeatin), and when the seed germinates, it moves from the endosperm…

With applications of chlormequat at 10 to 320 ppm to cotton plants ((3. hirsutum L. and 2° arboreum L.), 70 to 80 days old, Oosterhuis (1995) noted that plant growth was retarded and yield was significantly increased by increasing the number of bolls/plant and boll weight. The highest yield increases (18 to 45%)' in (3. hir sut um L. cult ivars occurred with a spray of 40 ppm while yield increased in G_. arboreum L. cult ivars (16 to 34%) with an application of 160 ppm. and Stewart (2005)…

In “Plant Pigment,” by Shirley Raps and Jeffrey Harborne, two types of plant pigments are discussed: photosynthetic and nonphotosynthetic pigments. Photosynthetic pigments are responsible for absorbing light and transferring energy during photosynthesis. Among this group of pigments are chlorophylls, phycobilins, carotenoids, and reaction center pigments which causes plants’ green, blue, yellow and orange colors, respectively. Nonphotosynthetic pigments are used to attract insects for…

reason the fall solo is because the chlorophyll in the leaves break down and the green color in the leaves disappears do to the weather changing. Chlorophyll is what gives leaves their green color. In the fall, cooler and shorter days make an end to auxin production. This allowed for the layer tp grow and to cut off the circulation of water. When this happens, chlorophyll falls apart and quickly. When there's less sun, athocyanin isn't really chemically active and the leaves are more orange,…

B) as a liquid. C) covalently bound to sugars. D) coupled to ion transport. E) via endocytosis. Answer: B Topic: Concept 35.2 Skill: Synthesis/Evaluation 25) Plants contain meristems whose major function is to A) attract pollinators. B) absorb ions. C) photosynthesize. D) produce more cells. E) produce flowers. Answer: D Topic: Concept 35.3 Skill: Knowledge/Comprehension 26) A cell that is most likely to retain the ability to divide, perform metabolic functions, and…

Article number 1 begins by talking about how plants cannot survive in total darkness and how darkness &light affect the growth of a plant in different ways. Plants cannot survive in total darkness as they use the suns energy and through a process convert it into food, this process is called photosynthesis. The plants that need sunlight to survive, which are majority of plants are called autotrophs. The presence/absence of light and dark play an important role in a plants as they trigger…

increase in gene family complexity; loss of genes associated with aquatic environments (e.g., flagellar arms); acquisition of genes for tolerating terrestrial stresses (e.g., variation in temperature and water availability); and the development of the auxin and abscisic acid signaling pathways for coordinating multicellular growth and dehydration response. The Physcomitrella genome provided a resource for phylogenetic inferences about gene function and for experimental analysis of plant…

Peanut, (Arachis hypogaea L.) is an herbaceous annual plant of the family Fabaceae grown for its oil and edible nuts. Peanut plants are small, usually erect, thin stemmed with feather-like leaves. The leaves are arranged in alternate pairs with leaf-like attachments near the stalk. The peanut plant produces yellow, orange, cream or white flowers which produce 'pegs', characteristic floral structures which sink into the ground to grow the pod. The pods could be reaching up to 10 cm (4 in) in…

Agent Orange: The Perpetual Consequences Generations of Vietnamese civilians exposed to a perilous chemical: all due to the spraying of an herbicide over Vietnam’s jungles. The Vietnam War was between the Communist North Vietnam and the United States. The conflict became global when Communist-supportive countries began sending reinforcements to the Vietnamese and the United States gained support from its allies. The Viet Cong soldiers knew their jungles by heart and used the plant cover to…
