The difference between pinocytosis and receptor-mediated endocytosis is that:

#Unit 2. Cellular Organization
  1. pinocytosis brings only water molecules into the cell, but receptor-mediated endocytosis brings in other molecules as well

  2. pinocytosis increases the surface area of the plasma membrane, whereas receptor-mediated endocytosis decreases the plasma membrane surface area

  3. pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity

  4. pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot

II) negative (repressing) senescence regulators
a) Hormones involved-Ethylene, Abscisic acid (ABA)
b) Hormones involved-Brassinosteroids (BRs), Salicylic acid (SA), Jasmonic acid (JA)
c) Hormones involved-Cytokinin, Auxin, Gibberellin (GAs)

Many of the carriers of Sucrose–H+ symporters in the phloem play various role in transport, most of the transporters are found in source, path, and sink tissues. Some carriers are characterized such as;
a) SUT1, has high-affinity / low-capacity transporter found in the minor veins of source tissues, appears to be important in phloem loading.
b) Important role of SUT1 in phloem loading appears to be complemented by SUT4, which is low-affinity/high-capacity carrier
c) SUT2, appears to function as a sucrose sensor. This is indicated by findings showing that SUT2 is more highly expressed in sink and path tissues than in source leaves.
d) The major sucrose transporters in phloem loading into the companion cells and final uptake into companion cells appears to be the function of SUT4
