- Briefly explain how water moves through a plant. Include how and why water moves through both xylem and phloem.arrow_forwardMake a simple HAND DRAWN sketch or flow diagram toillustrate the flow path of water through a plant, from the point of uptake from the soil totranspiration from the leaves. Ensure that you incorporate the following aspects in your sketch / diagram:• Water movement from the soil into the root, to the vascular tissues and the rest of theplant and into the atmosphere.• Label all the organs, tissues and structures involved in water uptake and transport.• Mention the mode of water movement (e.g. diffusion, osmosis, mass flow) whereapplicable along the symplastic and apoplastic pathways of water uptake and transportarrow_forwardWhich of the following adaptations allowed plants to grow in drier environment but without much water loss form its tissue? O A. Plant meristem tissue B. Plant alkaloids OC. Plant cuticle O D. Plant flavonoidsarrow_forward
- The movement of water out of phloem sap and back into xylem vessels is often associated with which of the following events? active transport of water out of the phloem sap into a source а. b. passive diffusion of phloem sap into a source active transport of sugars out of the phloem sap into a sink C. hydrostatic push (pressure) forcing phloem sap into a sink Od.arrow_forwardB) If you have a mesophyll cell in a leaf (a living, parenchyma cell in a leaf) with a slight positive turgor pressure (Yp = 0.01 MPa) and solutes (Ys = -3.0 MPa), and it is next to a xylem vessel element with very few solutes in the xylem sap (Ys = -0.01 MPa) but high physical tension (Yp = - 2.0 MPa), which way will water flow? a) from the mesophyll cell into the vessel element b) from the vessel element into the mesophyll cell c) neither direction. They are at equilibrium. Activa GoroSearrow_forwardPlant growth is achieved through both cell division and cell elongation. Cell elongation… I. Occurs in the direction parallel to the youngest microfibrils of the cell wall II. Is due to turgor pressure as water moves primarily into the vacuole III. Is arrested when the secondary cell wall forms outside of the primary cell wallarrow_forward
- When farmers apply too much fertilizer to the ground, the solute concentration is higher in the soil than it is in the roots. Explain how this would affect plants. And place these structures in the order that water passes through them during transpiration: endodermis, root cortex, root hair, spongy mesophyll, stomata, and xylem. -Thank you!arrow_forwardDescribe the pathway water would follow from the soil to the stem of a plant. Describe the water's movement through the cells, tissues, and systems of the plant body.arrow_forwardThe electrochemical gradient is __________________. A. The total chemical potential gradient B. The total electrical potential gradient C. All the above Water and mineral nutrients are transported from root to shoot via __________________ A. Plasmodesmata B. Xylem C. Phloem D. Cell wallarrow_forward
- This is the location of the carbon fixation reactions in C4 plants. Select one: a. the leaf's spongy mesophyll b. none of these answers c. the leaf's bundle sheath cells d. the palisade mesophyll e. the nearest apical meristemarrow_forwardFollowing infection with a pathogen, one response is to spread an alarm signal to increase defenses and antimicrobial compounds throughout the plant body and the network of plants connected by mycorrhizae. Which chemical spread this alarm signal? Select one: a. Salicylic acid b. Jasmonic acid c. Indole acetic acid d. Gibberellic acid e. Abscisic acidarrow_forwardBy which thing the difference in concentration of ions between roots and soil is eliminated?arrow_forward
