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.

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.
Green algae and plants differ in which of the following?
Algae have alternation of generations but land plants do not.
Green algae are often unicellular, while land plants are not.
Land plants have plastids and green algae do not.
Land plants have cell walls containing cellulose but green algae do not.
If you were to open the container at the end of the stalk shown in the image below, the cells you would find within
would eventually grow into:

- 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? Explain.arrow_forwardPlants in Clade Streptophyta and the green algae share a number of common traits, except for which choice? -both have cellulose in their cell walls. -both are multicellular -both are autotrophic. -both have apical meristems -both have chlorophyll a and b.arrow_forwardStudy the following image:arrow_forward
- 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.arrow_forwardCan 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_forward
- Put 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_forwardXerophytes 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. (photo below; arrows indicate filaments penetrating root)arrow_forward
- Both plants and Echinoderms have vessel like element that move water (plants have xylem, Echinoderms have a water vascular system). Is there ever a point (and if so, when and why) that xylem moves sugars? And is this a case of convergent or coevolution in terms of the vessels?arrow_forwardVascular plants evolved to have the apomorphic characteristics that enabled them to grow with greater height and thrive with efficiency in sustaining more complex structures. Select one: O True O False The sporophyte structure in vascular plants is dependent on the gametophyte structure. Select one: True False The presence of lignin in the secondary cell wall structure of vascular plants acts as a cementing agent between cellulose fibrils.
