Tissues And Supporting Systems:

What is the tissue responsible for transporting water and minerals from the roots to the rest of the plant?

Answer Details

The tissue responsible for transporting water and minerals from the roots to the rest of the plant is called the **xylem**. Xylem is a specialized plant tissue that is found in the stems and roots of plants. Its main function is to transport water, dissolved nutrients, and minerals from the roots, where they are absorbed, to the rest of the plant. The xylem is composed of several types of cells, including vessel elements and tracheids, which are long, tube-like structures. These cells are arranged end-to-end, forming a continuous pathway for water and minerals to flow through the plant. The movement of water and minerals in the xylem is driven by a process called transpiration. Transpiration occurs when water evaporates from the leaves of the plant through tiny pores called stomata. This creates a slight suction force, which pulls water up from the roots and through the xylem vessels. The xylem vessels are reinforced with a substance called lignin, which helps to provide support and prevent collapse. This allows the xylem to transport water and minerals against gravity, from the roots all the way up to the furthest leaves and branches of the plant. In summary, the xylem is the tissue responsible for transporting water and minerals from the roots to the rest of the plant. It uses specialized cells and the process of transpiration to create a continuous pathway for the movement of water and minerals throughout the plant.

Specimen H has a beak that is adapted for cracking hard shells of nuts and seeds. It also has strong feet and claws for perching and grasping food. ii. Specimen M has streamlined flippers that are adapted for swimming and diving. It also has a thick layer of blubber for insulation in cold water. ii. The organism that possesses specimen H feeds on nuts and seeds, while it also feeds on insects. c. I'm sorry, as an AI language model, I'm not able to make a drawing. d. The habitat of the organism that possesses specimen K is the aquatic environment, such as rivers, lakes, and oceans. e. The organism that possesses specimen H feeds on nuts, seeds, and insects, while the organism that possesses specimen L feeds on nectar and insects. f. i. Specimens H and L both have wings. ii. Specimens K and M both have adaptations for swimming in aquatic environments, with K having fins and M having flippers.
