What structure transports organic molecules from the leaf to other parts of the plant?
Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.
What is transported from leaves to other parts of the plant?
Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
What is the plant tissue that transports materials?
Plants have two transport systems – xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
What tissues in the leaf transport substances around a plant?
The main roles of plant stems and roots are to transport substances around the plant. They have two types of transport systems – xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
Why can a root be both a source and a sink when it comes to sugar transport?
A root growing through the soil can’t do photosynthesis. The embryo needs sugar to grow, but it can’t make it for itself. So it’s a sink for sugar and has low turgor pressure.
Which structure in the leaf transports organic molecules Group of answer choices?
Phloem tissue, which transports organic compounds from the site of photosynthesis to other parts of the plant, consists of four different cell types: sieve cells (which conduct photosynthates), companion cells, phloem parenchyma, and phloem fibers.
What are three types of ground tissue?
The ground tissue system arises from a ground tissue meristem and consists of three simple tissues: parenchyma, collenchyma, and sclerenchyma (Figure 5). The cells of each simple tissue bear the same name as their respective tissue. Figure 5: Cell types and tissues.
How is food transported to different parts of plant body explain?
The transport of food from the leaves to the other parts of the plant occurs through the vascular tissue called phloem. The food (sugar) made in leaves is loaded into the sieve tubes of phloem tissue by using the energy derived from ATP.
What are the three types of plant tissues?
They differentiate into three main tissue types: dermal, vascular, and ground tissue. Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).
What is the function of ground tissue?
Ground tissue makes up most of the interior of a plant. It carries out basic metabolic functions and stores food and water. Vascular tissue runs through the ground tissue inside a plant. It consists of bundles of xylem and phloem, which transport fluids throughout the plant.
What cells carry water around a plant?
The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.
Why can a root be both a source and a sink?
Belowground organs of plants (e.g. roots and rhizomes) are sinks during plant growth since they cannot perform photosynthesis. Some organs are both a source and sink. Rhizomes are sinks when growing but become sources in the spring when they provide energy for new growth.
