The sunlight that we see here on Earth actually left the Sun 10 minutes before.

The reason we see different colors of light is because each color has a different wavelength.

The cell membrane surrounds, protects and insulates every single cell of every organ or tissue in our body.

The cytoplasm is highly structured: it is not some kind of soup, even though it is made out of 75–80% water.

The single large vacuole of the cell is surrounded by a membrane, called the tonoplast, and filled with a solution of water, dissolved ions, sugars, amino acids , and other materials.
