Summary Introduction

To calculate: The pollen tube growth rate using the graph in the given question.

Introduction: Plants are multicellular, predominantly photosynthetic eukaryotes. They belong to the kingdom Plantae. Seed plantsare defined as plants that bear seeds. The two major types of seed plants are angiosperms and gymnosperms.

Explanation of Solution

The pollen tube is a tube through which the sperm from the pollen reaches the egg cells and fertilizes the plant to form seeds. The pollen grains are carried to the female gametophyte by a pollinator or wind. The growth rate of the pollen tube is calculated as (640 µm -80 µm)/(8 hr -1 hr) = 80 µm/hr using the graph in the given question.

Summary Introduction

To compare: The rate of pollen tube growth calculated by an individual with the rate in the table given in the question and propose an explanation for any differences.

Explanation of Solution

The growth rate of the pollen tube calculated by an individual with the rate in the table given in the question matches the value in the data table. The difference could be the result of reading the graph incorrectly or by rounding offduring calculation.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)   Data Table 1Stage    Totals    PercentInterphase        Mitosis:        Prophase        Metaphase        Anaphase        Telophase        Cytokinesis        Totals    100    100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
