everything is correct except for 3, the answer is b) the makeup of their cell walls.
i changed my answer for #6! I think its D now and for #8 i think that is B now
However, don't change your name. This makes us think that someone has actually answered you questions.
However, this is not my area of expertise.
6. In a mycorrhizal relationship, the benefit that the plant gets from the fungus is the aid in absorption of water and minerals. To get to this answer, you can analyze the options and eliminate the ones that are not applicable.
A. Energy Source: While some fungi may provide some energy to the plant, the primary benefit of mycorrhizal relationship is not the energy source. So it is not the correct answer.
B. Aid in seed dispersal: Mycorrhizal relationship does not involve seed dispersal. It is a symbiotic relationship between the roots of plants and fungi. So this option is incorrect.
C. Products of photosynthesis: The primary purpose of photosynthesis is to produce food (glucose) for plants, not to be provided by the fungi. Therefore, this option is incorrect.
D. Aid in absorption of water and minerals: This is the correct answer. Mycorrhizal fungi form a mutually beneficial relationship with the roots of plants. The fungi help extract nutrients, such as water and minerals from the soil, and make them available to the plant. In return, the plant provides the fungi with sugars produced during photosynthesis.
7. The correct answer is C. Most plants get the water they need from the soil. To arrive at this answer, we can evaluate each option.
A. Plants have adaptations that minimize light absorption: This statement is incorrect because plants need to absorb light for photosynthesis, so they have adaptations to maximize light absorption.
B. Plants require less water on sunny days: This statement is incorrect because plants typically need more water on sunny days due to increased evaporation and transpiration.
C. Most plants get the water they need from the soil: This statement is correct. Plants obtain water and nutrients from the soil through their root systems.
D. Plants take carbon dioxide from the atmosphere and do not use oxygen: This statement is incorrect because plants use carbon dioxide from the atmosphere during photosynthesis and produce oxygen as a byproduct.
8. The correct answer is B. An organism similar to green algae. To determine the correct answer, you can evaluate each option.
A. Mosses that lived in the water: Mosses are a type of land plant, but they are not thought to be the direct ancestors of land plants. So this option is incorrect.
B. An organism similar to green algae: This is the correct answer. The ancestors of land plants are believed to have evolved from green algae, which are aquatic organisms. The transition from water to land required adaptations to survive in a terrestrial environment.
C. A Protist that lived on land: While it is possible that some protists contributed to the evolution of land plants, the most widely accepted theory is that land plants evolved from green algae. So this option is incorrect.
D. Prokaryotes that carried out Photosynthesis: Prokaryotes, such as cyanobacteria, were responsible for the initial development of photosynthesis on Earth. However, they are not considered the direct ancestors of land plants. So this option is incorrect.
