Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. It could become, for example, xylem. 1. Xylem transports water and minerals from roots to the aerial parts in one direction only whereas phloem transports food and nutrients from leaves to different parts of the plants in upward and downward direction. It also contains parenchymatous as well as sclerenchymatous; It doesn’t perform mechanical function. (a) Xylem (b) Phloem (c) Meristematic Tissues (d) Permanent Tissues. toward the root and shoot) because phloem transports food from leave to other parts of the plant. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. 11. By this we can determine the age of tree. This tissue helps in the transport of water and dissolved substances throughout the plant. Only A. Phloem: It transports prepared food from the leaves to every part of plants. 651 Views. Further you will read components of phloem in tissues notes class 9. Phloem parenchyma is used to prepare and store food. 1. Location of phloem in plants: Ø Usually, the phloem is situated external to xylem. Phloem: Like xylem, phloem is also vascular but has no mechanical function. Question 9: Which of the following statments are True/False ? Solution: “A group of cells that are similar in structure and/or work together to achieve a particular function is called a tissue.” Blood, phloem, and muscle are all examples of tissues. Xylem and phloem are the two types of vascular tissues, present in plants and together constitute vascular bundles.Their function is to efficiently transport the materials which can be food, water, nutrients, organic materials, etc. Xylem and phloem are the names for the special pipe-like system that allows water and food to get delivered to all parts of a plant. The material (food) can move in both the directions (i.e. Also, the chlorenchyma of phloem parenchyma prepares food by process of photosynthesis. Sieve tube is an integral component of the phloem which is composed of several sieve tube elements which join end to end to form a channel for conduction. Ask your question.
