. MAKE CONNECTIONS Does the life cycle of humanshave any structures analogous to plant gametophytes?Explain your answer. (See Figures 13.5 and 13.6.)
1.Explain how vascular tissue allows vascular plants to be larger than nonvascular plants? Make reference to function of vascular tissue and how nonvascular plants obtain water and nutrients.
2.Describe why diffusion alone is an ineffective strategy to move nutrients/exchange gases in larger multicellular organisms.
3.Using your Life Concept Map as a reference, compare and contrast (give an account of similarities and differences between two items, referring to both items throughout the answer) a representative species from two similar kingdoms. A T chart or table might be a good way to organize your answers.
6 A classic experiment investigated the effect of
temperature on the rate of sugar transport in
a potted plant.
Aphid mouthparts were used to take samples
of sugar solution from the transport tissue in
the stem. The sugary solution dripped from
the mouthparts. The number of drips per
minute was counted.
The procedure was repeated at different
temperatures.
Table 1 shows the results obtained

- Test Your Understanding Evaluate and Synthesize 14. VISUALIZE construct a cladogram based on the following data. Mosses are plants with no vascular tissue. Horse-tails, ferns, gymnosperms (pines and other plants with naked seeds), and angiosperms (flowering plants) are all vascular plants. Seeds are absent in all but the gymnosperms and angiosperms. Angiosperms are the only seed plants with flowers. (Hint: To help you construct the cladogram, draw a simple table showing which characters are present in each group. See Fig. 23-9.)

Imagine you wanted to display a C. speciosa shoot in a vase in your house. You cut a flowering shoot (a shoot with both leaves and flowers on it) from a tree growing outside. You then transport the shoot into your house. As you carry it, the leaves and flowers are evaporating water. By the time you place the shoot in the vase of water, the relative water content (equivalent to relative cell volume) of the leaves and flowers has declined to…arrow_forward
