Of the two types of vascular tissue found in plants, which one has end walls, and two-way movement, and moves sugars around the plant? Group of answer choices Stomata Phloem Mycelium Xylem Lignin
Plant Structure and Growth
Roots anchor, the plant, ingest minerals and water, direct water and supplements, and store food. These are two kinds of root frameworks.
Plant Life Cycle
Plants are part of the PLANT KINGDOM, which is one of the five kingdoms of life. Plants are divided into smaller classes based on common characteristics. Certain characteristics are shared by all plants. They are made up of a large number of cells. They also make their own food through a chemical process called photosynthesis, which involves the use of water, carbon dioxide, and solar energy. They pump life-giving oxygen into the air as a by-product.
Life Cycle of Plants
All the organisms that belong to the Kingdom Plantae are known as plants. They are multicellular and eukaryotic and can synthesize their food by photosynthesis, known as autotrophic organisms. They are classified based on certain characteristics, such as the plants bear flowers; some have only naked seeds and do not contain flowers. Some plants neither have seeds nor flowers, such as ferns and mosses.
Plant Morphology and Anatomy
The study of life and organisms is biology. The cell is recognized as the basic unit of life by biology. From ancient Greek, biology is recognized. Modern biology deals with the recent developments in Science.
The vascular plants are called so because they have vascular tissue in them, there are two type of vascular tissue found in plants for the transport of different substances in plant body.
There are, Xylem and phloem.
The xylem is responsible for the transport of water from the roots to the upper parts of plant, and in leaves for photosynthesis and transpiration.
The transport of water in xylem is unidirectional i.e. it takes in one direction only from roots to the branches of tree.
The phloem is responsible for the transport of sugars most probably sucrose, produced after photosynthesis in leaves.
This sucrose needs to be transported to each and every tissue of the plant.
The transport of sugars in phloem is bidirectional, i.e. it could occur from leaves to bottom parts as well as from the bottom parts to upper plant parts.
During photosynthesis the sugars is produce in the leaves and it is transported to other parts of body after loading into phloem, this transport takes place from high concentration to low concentration parts of plant body as explained by Munch hypothesis.
This transported food is used by plant cells and the excess of it is stored in organs like roots.
During spring this process is reversed as during this time the stored food in roots is transported back to growing buds for their regrowth by phloem.
Thus the transport of nutrients in phloem is bidirectional.
