Translocation - Biology Encyclopedia - cells, plant, body ...

Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials. For this reason, nutrients are translocated from sources (regions of excess carbohydrates, primarily mature leaves) to sinks (regions where the carbohydrate is needed).

A corn plant is a monocot ; a tomato plant is a dicot. Cohesion of water molecules in the xylem of a plant is a result of: hydrogen bonds between the oxygen of one water molecule and a hydrogen of another water molecule. Sugars are transported through the phloem: All of the above are correct.

Companion cells are normal plant cells with high numbers of mitochondria and ribosomes, and have many plasmodesmata pass through to their neighbouring sieve cell walls, making direct contact between the cytoplasm of companion cells and sieve elements. Mass Flow . Mass flow is the theory by which we think solute transport occurs in plants.

Transport Across Cell Membranes - biology-pagesfo

Active transport is the pumping of molecules or ions through a membrane against their concentration gradient. It requires: a transmembrane protein (usually a complex of them) called a transporter and energy. The source of this energy is ATP. The energy of ATP may be used directly or indirectly. Direct Active Transport.

Plasmodesma - Wikipedia

Plasmodesmata are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them. Plasmodesmata evolved independently in several lineages, and species that have these structures include members of the Charophyceae, Charales, Coleochaetales and Phaeophyceae, as well as all embryophytes, better known as land .

Aug 13, 2007 · Now every part of the plant needs food and other substances. So these substances are to be transported to all the parts of the plants like roots, stems, growing regions etc. The movement of food from leaves to other parts of the plant is called Trans location. In plants, phloem Trans locates the food and other substances.

How Plants Send Sugars from Sources to Sinks - dummies

Plants use a special tissue called phloem to transports sap — a sticky solution that contains sugars, water, minerals, amino acids, and plant hormones. Sap moves through phloem via translocation, the transport of dissolved materials in a plant. Unlike the xylem, which can only carry water upward, phloem carries sap upward and downward, from sugar sources to sugar sinks:

Some molecules are known to be transported through this channel, but it is not thought to be the main route for plasmodesmatal transport.

Let's start with water. The movement of water in a plant is like a one-way street, it is unidirectional and it travels along this route: soil -> roots -> stem -> leaves -> air. The movement of water throughout a plant is driven by the loss of water through it's leaves, or transpiration.

Even transport of molecules, such as water and urea, that can diffuse across pure phospholipid bilayers is frequently accelerated by transport proteins. The three major classes of membrane transport proteins are depicted in Figure 15-3a. All are integral transmembrane proteins and exhibit a high degree of specificity for the substance transported.
