Textbook Question
Chapter 34, Problem 15TYK
Apply Evolutionary Thinking A variety of structural features of land plants reflect the conflicting demands for conserving water and taking in carbon dioxide for photosynthesis. Identify at least four fundamental structural adaptations that help resolve this dilemma and explain how each one contributes to a land plant’s survival.

SUBJECT: GENERAL BIOLOGY 1 / CAM and C4 Photosynthesis
Plant adaptation is varied among all organisms present on Earth’s fauna. Also,
we can’t deny the fact that as time goes by, the amount of carbon rises making it
more complicated for the rest of organisms to adapt and survive.
In relation to their specialized features, predict how C4 and CAM plants will each respond to a doubling
of the concentration of CO2 in the atmosphere.
Which of the following statements about age gradients within the plant body is FALSE?
Select one:
a. Age gradients within the plant body include an apical-basal gradient where the youngest cells are near the apices (tips of shoots and roots).
b. Age gradients within the plant body reflect the plant cells’ lack of mobility due to their shared walls.
c. Phloem is oldest toward the outermost cell layers of the tree trunk and xylem is oldest toward the innermost cell layers of a tree trunk.
d. All of the statements are true.
e. Age gradients within the plant cells include walls that are youngest immediately adjacent to the plasma membrane and progressively older toward the middle lamella.
Sudents are asked to pair a plant structure to its physiological function and give evidence for why that structure is important for the process they describe
Anne: The root hairs are used to pull in sugars available in the soil that give the plant energy for growth and reproduction.
Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves in order to perform cellular respiration.
Shantal: The cambium is important for phossynthesis because it allows water into the plant which is needed as a reactant for photosynthesis.
Enrique The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant.
Which student correctly described a plant structure and its physiological function?
O Anne
Jamil
O Shantal
O Enrique

- Evolutionary biologists have coined the term exaptation to describe a common occurrence in the evolution of life. A plant organ originally has a particular function, however, fulfills a new one. Provide two examples of exaptation in plant organs and elaborate comprehensively.arrow_forwardA mutation causes the vascular cambium in a plant to stop working. How does this impact cellular respiration? The stomata would remain open and release water vapor. The guard cells would remain closed and store water vapor. The leaves would not be able to release glucose for energy production. The xylem would not be able to transport water to the rest of the plant.arrow_forward) Interactions between plants and other organisms can be complex and key to organisms continued survival. Joshua Tree National Park is home to the iconic Joshua tree plant, which is actually a very large species of yucca (Yucca brevifolia) with a tree-like appearance. This is a long-lived species (hundreds of years). There are many challenges to the continued survival of these plants. Mature plants can store water allowing them to survive droughts, young plants have a smaller water storage capacity and thus will die off in dry times. The only known pollinator of these plants is the yucca moth, which is becoming absent through most of the range of the yucca plant as the moth does not tolerate the increasingly warm climate in the region. The warmer climate also decreases flowering (the plants need cold to induce flowering). Adding to this challenge is the lack of natural seed dispersal of yucca. It is though that historically the seeds of this yucca were dispersed by the now…arrow_forward
- When plants first moved on to land, they faced with a wide variety of new challenges. Two of these challenges include the risk of drying out and the ability to access/transport resources. Describe not just list 4 adaptations that allow plants to cope with these challenges, 2 for coping with drying out and 2 for coping with accessing/transporting resources.arrow_forwardPlant shoots include stems, leaves, and flowers. Monocot stems have their vascular bundles arranged in a ring pattern in the ground tissue. Eudicots have their leaf veins arranged in a parallel pattern. Photosynthesis in leaves takes place in the mesophyll layer Eudicots possess a large taproot.arrow_forwardFrom the option given below which of the following is not an adaption that helps plantsresist gravity and dry conditions on land?1. xylem2. lignin3. cuticle4. photosynthesisarrow_forward
- Study the following image:arrow_forwardT/F Question Parenchyma is soft, internal plant tissue. Xylem and phloem are plant structural tissue. Periderm tissue is a type of plant epidermis in young stems and roots. Plant shoots include stems, leaves, and flowers. Monocot stems have their vascular bundles arranged in a ring pattern in the ground tissue. Eudicots have their leaf veins arranged in a parallel pattern. Photosynthesis in leaves takes place in the mesophyll layer Eudicots possess a large taproot. The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots. Plants can undergo asexual reproduction without cross-pollination. The fertilization process in plants is a double fertilization process. Over 1/3 of the U.S. food supply comes from the cross-pollination…arrow_forwardWhich of the following resource(s) do plants need to survive (select all that apply): A.
