Question 1

Suppose that,while on a forest hike,you notice a blue fungus and a pink plant growing along the hiking trail.As you continue walking,you observe that if a blue fungus and a pink plant are growing side by side,they are both much larger than if the fungus and the plant are farther apart.What can you hypothesize about the relationship between the fungus and the plant?

Accepted Answer

The observation that the blue fungus and pink plant are much larger when growing side by side suggests that they have a mutually beneficial relationship. This type of interaction is known as a symbiotic relationship, where both species benefit. In this case, it is likely that the pink plant provides nutrients to the blue fungus in exchange for the fungus providing the plant with some sort of benefit, such as protection from pathogens or enhanced nutrient uptake.

Question 3

What important role do fungi play in many ecosystems?

Accepted Answer

Fungi are primary decomposers in many ecosystems, breaking down dead organic matter and recycling the nutrients back into the soil. They play a crucial role in nutrient cycling and soil health, which in turn supports the growth of other organisms in the ecosystem. Fungi do not perform photosynthesis, pollinate plants or disperse fruits of angiosperms.

Question 4

What are hyphae?

Accepted Answer

Hyphae are threadlike filaments that make up the bodies of fungi. They are responsible for the absorption of nutrients from the environment.

Question 7

Scenario Questions
Read the following scenario to answer the following questions.
People utilize plants to meet many everyday needs, including food, fiber, and building materials. However, not many of the over 300,000 known species of plants are used by people. One species with a lot of future promise is the jatropha tree. This species is native to Central America and is now found throughout the tropics. Many people believe the jatropha could help alleviate poverty in many areas of the world, as the seeds produce an oil that can be used for cooking, lighting, or generating electricity. This oil can also be mixed with diesel fuel or petrol to produce a biofuel. Mature trees produce between 5 and 15 kg of seeds per year and can live more than 30 years. However, critics argue that planting the jatropha tree will take land needed for food production, which will in turn harm the poor.
-Which of the following statements concerning the jatropha tree is TRUE?

Accepted Answer

The passage states that the jatropha tree's seeds produce an oil that can be used for various purposes, indicating that the most valuable part of the tree is the seed.

Question 8

Like plants,fungi have ________; however,in plants they are composed of ________,whereas in fungi they are composed of ________.

Accepted Answer

Fungi have cell walls, just like plants, but instead of being composed of cellulose (which is found in plant cell walls), they are composed of chitin.

Question 9

...

Question 10

If seed production had never evolved,which organisms would be missing in today's landscape?

Accepted Answer

Gymnosperms and angiosperms both rely on seed production for reproduction. If seed production had never evolved, both of these groups of plants would not exist in today's landscape. Bryophytes and ferns, however, rely on other means of reproduction such as spores and would still be present. Therefore, the correct answer is C, gymnosperms and angiosperms.

Question 11

The function of a mushroom is to ________.

Accepted Answer

The primary function of mushrooms is to produce spores, which are used for reproduction. Mushrooms do not produce seeds, store nutrients or photosynthesize.

Question 12

Biocontrol,short for biological control,is a means to control pest populations (e.g.,insects,plants)by intentionally introducing natural enemies of those pests.Biocontrol methods have benefits of typically being less expensive and less environmentally damaging than chemical pesticides.Which of the following should NOT be considered an example of biocontrol?

Accepted Answer

The application of herbicides is not a form of biocontrol as it involves the use of chemicals rather than natural enemies to control pest populations.

However, critics argue that planting the jatropha tree will take land needed for food production, which will in turn harm the poor.
-What would NOT be an advantage of using oil from jatropha seeds?

Accepted Answer

Critics argue that planting jatropha trees will take land away from food production, which may harm the poor. Therefore, using jatropha oil may not be an advantage in terms of food security. The other options (A, B, and C) are all advantages of using jatropha oil.
