Expert Solution & Answer

Explanation of Solution

The red light is absorbed by the leaves at a greater rate than the far-red light, as the sunlight passes by the canopy. The relative amounts of far-red and red light are integrated by plant signaling through phytochrome to regulate the growth and development of plants. For example, germination of seed is inhibited as the relative amount of far-red light increases. Therefore, in a below shady canopy, germination of seeds would have less chance of survival because of reduced photosynthesis. Alternatively, the information about the reduced sunlight could signal rapid elongation of stem to get the plants closer to adequate sunlight for photosynthesis.

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.
