Answer:
Las hormonas pertenecen al grupo de los mensajeros químicos, que incluye también a los neurotransmisores y las feromonas. A veces es difícil clasificar a un mensajero químico como hormona o neurotransmisor.
Todos los organismos multicelulares producen hormonas, incluyendo las plantas (En este último caso se denominan fitohormonas).
Explanation:
The answer is most likely "vascular system". Xylem tissue is a part of a plant's vascular system. Which is mostly responsiple for transportation (of water, food etc.) in a plant. The vascular system of plants is made of two tissues. One is Xylem and the other is Phloem. Phloem transports food from leaves to all other parts of the plant. And Xylem transports water and minerals (which are dissolved in the water) to the leaves.
So if you remove the <u>Xylem</u> tissue from a plant, its vascular system will be affected.
Answer: Helps the plant breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.
