How do water & minerals move from the dermis to vascular tissue across the cortex? Asked by jessicaheidi - Mon Oct 29 16:47:16 2007 - - 2 Answers - 0 Comments A. Water and mineral enter through root epidermis, cross the cortex, pass into the stele, and are carried upward in the xylem. The cells cannot get enough mineral ions from the soil by diffusion alone. The soils solution is too dilute so active transport of these ions must occur. Specific carrier proteins in the plasma membrane attract and carry their specific mineral into the cell. A Proton Pump: H+ is pumped out of the cell causing a change in pH and a voltage across the membrane. This helps drive the anions and cations into the cell. Water and minerals cross the cortex in one of 2 ways: Via symplast which is the living continuum of cytoplasm connected by plasmodesmata. Via apoplast which is nonliving matrix of cell walls.

Q. What are the functions of the dermis? Asked by ednalyn h - Sun Aug 12 09:25:45 2007 - - 4 Answers - 0 Comments A. Skin performs the following functions: - Protection: an anatomical barrier between the internal and external environment in bodily defense; Langerhans cells in the skin are part of the adaptive immune system - Sensation: contains a variety of nerve endings that react to heat and cold, touch, pressure, vibration, and tissue injury; see somatosensory system and haptics. - Heat regulation: the skin contains a blood supply far greater than its requirements which allows precise control of energy loss by radiation, convection and conduction to maintain blood flow and conserve heat. Erector pili muscles are significant in animals. - Control of evaporation: the skin provides on. Dilated blood vessels increase perfusion and heat loss while… [cont.] Answered by MarZ - Sun Aug 12 09:35:29 2007 From Yahoo Answer Search: "dermis" |
