There are multiple examples of plants having inflorescences that take on the form of an individual flower. Two such examples are in Asteraceae (capitulum) and Euphorbiaceae (cyathium). What would be an evolutionary advantage of flower-like inflorescences?

During photosynthesis plants take in inorganic Co, and water converting them to organic compounds such as glucose. Glucose can be utilized to produce energy or become stored in the form of starch in different parts of the plant. Some scientists wanted to learning more about the transporting system of plants, so they labeled the carbon atoms in the Co, so that they can trace their path through the plant's body. Which part of the vascular tissue of the plant you...
103-108, What are the 3 major secondary metabolites found in plants, and what are examples of each? Also illustrate their chemistry and list their functions in the space below 109-110. Beginning with the largest taxonomic unit, place the following in correct hierarchical order: phylum, domain, order, genus, species, kingdom, family, elass, subspecies 111-114. What are 5 key evolutionary similarities between the green algae and land plants? 115-117. How do humans use plants? (List 6 uses) We were unable to transcribe...
The form human needs take as they are shaped by culture and individual personality is called Select one: O Want O Personality O Need O Demand
What would be the evolutionary advantage to having the conduction velocity of neural impulses change with temperature, and which of the five major groups of vertebrate organisms might benefit most from this phenomenon? Explain.
Given the genotype AaBbCcDdEE a) How many kinds of gametes can this individual form? b) If selfing occurred, what fraction of the progeny would have the following genotype: AaBBccDdEE? A cross between two plants produces progeny which, through subsequent breeding experiments, are shown to fall into 27 genotypic classes. Assuming that complete dominance operates at all of the loci involved and that each locus has two alleles, a) At how many different loci are the parents heterozygous? b) How many...
1. Genetically identical plants are planted in a garden. Ones on the east edge of the garden produce blue flowers; the others produce pink flowers. How can this best be explained? environmental factors influence flower color the alleles are codominant the allele for blue flowers is dominant a mutation must have occurred multiple alleles affect flower color 2. In a species of mammal, some individuals are true-breeding for red hair. Others are true-breeding for brown hair. A true-breeding red individual...
(More Genetics Problems and Difficult Genetics Problems). MORE GENETICS PROBLEMS 1. When tall plants mate with dwarf plants, only tall plants occur in the offspring. Assign symbols and show the phenotypes and genotypes in the parental (P) and first filial generations for a cross between tall plants and dwarf plants that produces only tall plants. 2. Show the expected outcome when the F1 plants in problem #1 are crossed. Be sure to give both phenotype and genotype ratios for these...
Plants sometimes use other organisms as defences against herbivores. Provide two examples of biological defences used by plants to reduce the negative effects of herbivory. For each of them indicate what are the costs for the plant.
7. Which of the following is seen in plants with self-fertilization? a. Each individual plant only produces either male or female flowers b. Male and female flowers are produced in different parts of the plant c. Male and female flowers are produced at different points in time d. Pollen tube is incompatible with stigma from the same plant e. Flower bud never opens, pollen flows directly to the stigma 8. Select one outcome that is NOT the result of the...
