Describe three adaptations of hydrophytes (aquatic plants). Be sure that your descriptions explain how each adaptation is an advantage in an aquatic environment
Homework Answers
1. Roots-Poorly developed roots. Since hydrophytes have water all around, water adsorption is not an issue and therefore poor root hairs. A few hydrophytes do not have roots e.g Azolla. These adaptations make the plant lighter and also adapt them to survive in water.
2. Presence of mucilage covering- mucilage is released and coated onto the surface of plants which prevent the plants against decay while staying continuously in water.
3. Stems are soft and spongy. This helps the plant to stay afloat.

4. What does "scientific adaptation" mean? How is it different from the way we use the term "adaptation" in everyday language? 5. What two processes are necessary for adaptation to occur? 6. Genetic variation occurs randomly and increases the diversity of a population. Natural selection is nonrandom and decreases the diversity of a population. How do these two processes work together to produce adaptations in populations over time? 7. What are two possible outcomes of adaptations in lineages over time?...

Xerophytes are plants that are able to grow in arid environments. Explain how the following adaptations of xerophytes would recuce traspiration rates and enhance these plants' survival in arid regions: thick cuticle, sunken stomata (stomata are found in cavities), leaf surface covered with dense mat of trichomes.

5. Photosynthetic adaptations to extreme environments Aa Aa Rubisco carries out photorespiration when the ratio of O2 to CO2 is too high. As a result, certain plants have adaptations meant to keep this ratio low in tissue locations where their photosynthetic cells need to use Rubisco. The following image describes how when these two sets of events occu plants prevent photorespiration.

. Describe why CAM plants have an advantage over C3 plants in the desert and why C4 plants have an advantage over C3 plants in tropical climates. (Be sure to discuss the relevance of photosynthetic enzymes and their location, photorespiration, water use efficiency, and stomatal behavior and leaf anatomy.) 4. Thinking about anatomy, morphology, and “behavior” describe ways that plant leaves are adapted to intercepting light, increasing CO2 diffusion while reducing water loss. 5. In general terms, describe the characteristics...
