12 vascular tissue

13 d
9. While I don't know of any rice cloth, the others sisal and bamboo,and flax can all be made into paper or cloth. A guick google search confirms this.
8 d

For question 8, the correct answer is d. albinism treatment.

For question 9, the correct answer is a. bamboo and flax.

For question 12, the correct answer is b. vascular tissue.

For question 13, the correct answer is d. all of the above.

8. To determine the correct answer for the medicinal uses of plants, we need to understand what each option means and eliminate the one that does not fit.

- Option a: Cancer treatment. Many plants contain compounds that have anti-cancer properties, so this is a possible medicinal use of plants.
- Option b: Treatment of cardiac disorders. Some plants have been used for centuries in traditional medicine to treat heart conditions, so this is a possible medicinal use.
- Option c: Decongestant. Some plants have properties that can help relieve congestion and are used as decongestants in various forms such as teas or essential oils. This is a possible medicinal use.
- Option d: Albinism treatment. Albinism is a genetic condition that affects the production of melanin, which gives color to the skin, hair, and eyes. It is highly unlikely that plants are used in the treatment of albinism, so this is the exception.

Therefore, the correct answer is d. Albinism treatment.

9. To determine the plants used to make both paper and cloth, we need to understand the options and identify the ones that are used in both industries.

- Option a: Bamboo and flax. Bamboo is commonly used in the production of paper, and flax is used to make linen cloth. Both plants fit the criteria.
- Option b: Flax and cotton. Flax is used to make linen cloth, but cotton is not typically used in paper production.
- Option c: Sisal and bamboo. Sisal is used to make rope and fibers, but it is not commonly used for paper production.
- Option d: Rice and cotton. Rice is not used in either paper or cloth production, and cotton is typically only used for cloth.

Therefore, the correct answer is a. Bamboo and flax.

12. To identify the "plumbing system" that transports water and nutrients throughout a plant, we need to understand the options and select the one that fits the description.

- Option a: Epidermis. The epidermis is the outer protective layer of the plant, but it does not transport water and nutrients.
- Option b: Vascular tissue. Vascular tissue, composed of xylem and phloem, is responsible for conducting water, minerals, and sugars throughout the plant.
- Option c: Pith. Pith is the soft, spongy tissue in the center of some plant stems. It does not transport water and nutrients.
- Option d: Transpiration. Transpiration refers to the process of water loss from the plant through small openings called stomata. It is not the system that transports water and nutrients.

Therefore, the correct answer is b. Vascular tissue.

13. To identify the cause of water movement through a plant, we need to understand the options and select the one that applies.

- Option a: The attraction of water molecules for each other. Water molecules are cohesive, meaning they are attracted to each other. This cohesion helps facilitate the movement of water through the plant.
- Option b: Osmosis. Osmosis is the movement of water across a semipermeable membrane. While osmosis does occur in plants, it is not the primary cause of water movement through the plant.
- Option c: Transpiration. Transpiration, the loss of water vapor from the plant through stomata, creates a negative pressure that pulls water up through the xylem.
- Option d: All of the above. This option combines all the previous options and includes the correct explanation.

Therefore, the correct answer is d. All of the above.

Final Answers:
8. The correct answer is d. Albinism treatment.
9. The correct answer is a. Bamboo and flax.
12. The correct answer is b. Vascular tissue.
13. The correct answer is d. All of the above.
