WebPhloem is a specialised living tissue that transports amino acids and sugars from the leaves (source) to the growing parts of the plant (sink) in a process called translocation. This process is bi-directional. A source is a plant region that generates organic compounds, … WebDescribe the structure of phloem and explain how it is adapted for its function Little cytoplasm, no organelles - room for water, sucrose etc. to be transported Perforated ends - let water, sucrose through easily Companion cells have many mitochondria to produce ATP for active transport
WebMar 28, 2024 · Xylem and phloem give vascular plants their classification; they are the vascular tissues that transport substances throughout the plant. Function of Xylem The main function of xylem is to transport water, … Webxylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known …
WebThe adaptations and characteristics which ARE present in (nearly) all land plants include: A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light. WebThe two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant. Most extant plants on Earth have vascular systems, including the lower vascular plants ( lycophytes and ferns ), gymnosperms, and angiosperms.
WebPhloem is the second type of vascular tissue; it transports sugars, proteins, and other solutes throughout the plant. Phloem cells are divided into sieve elements (conducting cells) and cells that support the sieve elements. Together, xylem and phloem tissues form the vascular system of plants.
