1. Plant seed coats,cuticles, and mycorrhizae prevent water loss from the seed or plant. So answer B is wrong.
C makes no sense to me. How do they enhance carbon dioxide release?
2. all of the above.
1. Plant seed coats, mycorrhizae, and cuticles are examples of ways plants have adapted to life on land. The answer is A.
1. Plant seed coats, mycorrhizae, and cuticles are examples of a. ways plants have adapted to life on land. Answer: A
2. Stomata help plants d. all of the above: survive on land, allow oxygen exchange, and release water vapor. Answer: D
Hope this helps!

1. The answer is a. ways plants have adapted to life on land.
To arrive at this answer, we need to understand the function of each of the examples given - plant seed coats, mycorrhizae, and cuticles.
- Plant seed coats: Seed coats protect the plant embryo and help facilitate seed dormancy, allowing plants to survive in unfavorable conditions and disperse their offspring.
- Mycorrhizae: This refers to the mutually beneficial association between plant roots and certain fungi. Mycorrhizae enhance the plant's ability to absorb nutrients, especially phosphorus, from the soil.
- Cuticles: Cuticles are waxy coverings found on the surface of leaves and stems in many plants. They help reduce water loss by forming a barrier that limits the evaporation of water from plant tissues.
Considering these functions, it becomes apparent that all three examples are adaptations that enable plants to thrive in terrestrial environments, making option a the correct answer.
2. The answer is d. all of the above.
Stomata are tiny openings found on the surface of plant leaves and stems that play several crucial roles for plants. They allow for the exchange of gases, such as oxygen and carbon dioxide, between the plant and its surroundings. This is essential for photosynthesis, as plants need carbon dioxide for the process and release oxygen as a byproduct. Stomata also regulate the release of water vapor through a process known as transpiration, helping plants maintain proper hydration levels and cooling the plant in the process.
Since stomata assist in all of these functions - allowing for gas exchange, oxygen release, carbon dioxide absorption, and water vapor release - option d is the correct answer.
