Phloem layer
Webb25 okt. 2024 · The phloem tissues are made up of tubes-like vessels called phloem vessels, and the phloem tissues transmit information between them. They carry dissolved organic solutes like sucrose and amino acids from the plant’s sources to the sinks, and they run from the leaves into the rest of the plant. WebbA) Roots anchor a plant in soil, and in many species, they store nutrients. B) An extensive root system provides a plant with a very large surface area for absorbing water from the soil. C) When a seed germinates, the first structure to emerge from it is a root.
