Plasmodesmata can change in number, and when dilated can provide a passageway macromolecules

Plasmodesmata are essential for the intercellular transfer of both big informational macromolecules like proteins and smaller signaling chemicals in plant cells.

  • Plasmodesmata are membrane-lined structures that offer a high-conductance, aqueous channel for the transportation of information in the form of chemicals and macromolecules, such as transcription factors, from cell to cell.
  • The intimate interaction of the plasma membrane with the endoplasmic reticulum results in the formation of plasmodesmata.
  • The degree to which a particular cell acts as an individual or as a component of the entire organism is determined by the distribution and unitary conductance of plasmodesmata as well as other positional variables that affect development.

<h3>What is genetic variation in population?</h3>
  • The presence of various alleles, or different gene versions, within a population indicates genetic variety.
  • If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
  • Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
