Textbook Question
Chapter 36, Problem 9TYU
EVOLUTION CONNECTION Large brown algae called kelps can grow as tall as 25 m. Kelps consist of a holdfast anchored to the ocean floor, blades that float at the surface and collect light, and a long stalk connecting the blades to the holdfast (see Figure 28.12). Specialized cells in the stalk, although nonvascular, can transport sugar. Suggest a reason why these structures analogous to sieve-tube elements might have evolved in kelps.

Evolution of Photosynthetic Organisms
Algae are autotrophs and can have photosynthesis, however, evolutionary evidence suggests that plants
shared a common ancestor with only green algae and are closest relatives of Charophytes. What evidences
support this statement? How an algal cell is different from fungal cells, even if both are eukaryotes? Why
slime mold is a protist not a fungus even if it does not have chloroplast?
Renly
The chlorophyte (green algae) genera Ulva and Caulerpa both have macroscopic leaf-like and stem-like structures, but only Ulva species are considered truly multicellular. Explain why.
Many fungi are decomposers and degrade organic matter (such as wood and leaf litter). It has become clear that many of these decomposers are also able to colonize live plants as endophytes (living inside the plant without causing any harm) and allowing for prime access to plant tissues once the plant dies. Explain, using the principles of natural selection, how having the ability to be both a decomposer and endophyte evolved. Make sure you include the four steps of evolution by natural selection in your response.

- EVOLUTION LINK The number of protonephridia in a planarian is related to the salinity of its environment. Planaria inhabiting slightly salty water develop fewer protonephridia than those inhabiting less salty water, but the number of protonephridia quickly increases when the concentration of salt in the environment is lower. How is this increase adaptive?

- Can you answer this questionarrow_forwardOne evident apomorphy evolved in vascular plants is the establishment of true leaves which is characterized by the incorporation of the vascular system. Select one: True False The calyptra in mosses generally function in the regulation of gas exchange and water uptake. Select one: True False Elaters are non-sporogenous cells with spiral wall thickenings and is mainly for spore dispersal of liverworts. Select one: O True Falsearrow_forwardPut the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forward
- Xerophytes have adaptations such as having a waxy leaf cuticle that will make them survive in hot and dry environments. How does this adaptation help reduce water loss? * It increases the ability of the leaf cells to absorb water. NO answer It reduces the surface area for transpiration. It is impermeable to water, thus stops evaporation. It traps moist air, which increases the humidity and reduces the diffusion of water vapor.arrow_forwardAt Walden pond part 2: You gently pull up a plant and see fine white filaments covering the roots (see photos bleow). Thin sections through the roots and filaments show the filaments surrounding the root and penetrating between the plant cells of the root.
