carbon dioxide at normal atmospheric concentrations is limiting for the metabo- lism and growth of most land plants of the world. These plants share a comparable photosynthetic metabolic pathway, termed C3 photosynthesis. With an increase in CO2 there is an increase in photosynthesis and growth.
Explanation:
T killer cell or Cytotoxic T cells are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes.
<u>Explanation</u>:
The T cells kills the bacteria and virus. The T cells can easily identify the pathogen when combined with the lysosomes. The activated T cells releases a material called perforin. This substance gets into the walls of the affected cell and punctures its walls. Due to hole in the walls, there happens discharge of fluid and electrolytes, which leads to the death of the cell. The substance secreted is the cytolytic proteins from the lysosome which helps in destruction of the infected cells.
