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.

<span>Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.</span>

In step 1, the insulating plate (such as plastic) becomes positive charged when rubbed with cloth. what is the name of this phen
CaHeK987 [17]
An insulating plate, such as plastic, tends to be positively charged when rubbed with cloth due to the piezoelectric effect. This phenomenon involves certain materials to generate charged particles as a response to mechanical stress applied to it. In this case, the mechanical stress was due to the rubbing motion.
