In the Kotukutuku plant, Fuchsia excortiata, why do pollinated flowers remain attached to the plant for several days after pollination occurs and nectar is no longer produced Size of flower and pollination Annual versus perennial reproduction Time and expense to grow the pollen tube outweighs the cost of maintaining the flower on the tree Size of flower and number of flowers on inflorescence

Follow the key on page 1 to direct the steps, alongside with it's illustration of key on page 2, to fill out the sheets on the second page of the each of the directed 16 species' labeled name, sequence of line choice, family, pollinator(s), and why this pollinator. Thank you.

The data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?

Angiosperms are the most diverse group of plants on the planet, by far. However, using flowers for reproduction does have potential disadvantages. Briefly describe two possible challenges (e.g., problems, risks, costs, etc.) that might be associated with using flowers as a reproductive strategy.

Describe the challenges for plants in terms of resource circulation or dispersal of reproductive structures from an evolutionary perspective (as they moved from single celled to colonial, to small and then large terrestrial forms. Describe the progression of structures from early evolutionary groups to later evolutionary groups to solve one of these challenges in 2-4 paragraphs

What preliminary conclusions can you draw from the results of the experiment and what is the independent and dependent variable ?

The best answer describing angiosperm fertilization is: O a single sperm fertilizes an egg a single sperm fertilizes the antipodal cells O a single sperm fuses with the two polar nuclei one sperm fertilizes the egg, one fuses with the two polar nuclei to create 3N tissue one sperm fertilizes the egg, one fuses with the antipodal cells to create 3N tissue

Directions: Plants have two life stages. The gametophyte life cycle, wherein a haploid spore is produced, and the sporophyte life cycle wherein there is union of the gametes. Below are different events in the development of flowering plants. Arrange them in the correct order. Place the number from 1 to 6 inside the box. The hypocotyl pushes to the soil along with the cotyledon(s). It starts as a seed which contain the miniature plant called embryo. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm Mature plant develops the gametes, releases the pollen and pollinates the flower. It is the process wherein seeds are transported, spread or moved away from the parent plant either by wind, water, animals or insect. The plant, given enough nutrients will develop in a mature stage.
