A membrana plasmática é basicamente uma borda entre o interior de uma célula e seu exterior. A membrana regula o que entra e sai da célula e é necessária para a sobrevivência da célula. sem ele, todo o conteúdo da célula se espalharia. Isso seria ruim. Cada célula tem uma membrana, assim como as organelas dentro da célula.
mRNA or Messenger RNA
mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. mRNA carries genetic information from the nucleus to the cytoplasm of a cell.<span>rRNA or Ribosomal RNA
rRNA is located in the cytoplasm of a cell, where ribosomes are found. rRNA directs the translation of mRNA into proteins.</span><span>tRNA or Transfer RNA
Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins</span>

Refraction- bending of light waves (ex. straw in a cup of water looks bent on a side but really is NOT, this is due to refraction, it bends the light waves reflected)
Luminescence- Creation/Emission/Starting or making of light through ways that DO NOT INVOLVE heat.
Ultraviolet- a wavelength that is part of the electromagnetic spectrum its shorter than visible light waves.
