AQA a level biology essay PLEASE help

I’m so confused about how to format this essay. I understand I need a knowledge section that’s straightforward enough but after I explain something do I need a whole paragraph for why it’s important or just a few lines?

Is this format fine where both knowledge and important are in the same paragraph? (Importance in bold)

If all my 4-5 paragraphs for my whole essay follow this format will I be fine?

The properties of water allow it to carry out important functions such as mass transport in plants. Water travels all the way up a plant through the xylem. Water leaves the leaves through transpiration. This decreases the pressure and water potential in leaves so water will move up the plant in a continuous column. Water can do this due to cohesion and adhesion properties. The H2O molecule is polar and can form hydrogen bonds with itself as cohesion and it can also adhere to the xylem wall. This makes water important as its properties allow the transpiration stream to occur so water can be transported from the roots to the leaves where it is used for photosynthesis in the light-dependent reaction. Water is also an important component in transport within the phloem. This is where dissolved solutes are transported from their source (photosynthesising leaf cells to the sink cells that require glucose for respiration. Water is important in this process as it is a good solvent so many substances are easily dissolved in it.

If anyone could advise me on the format I’d be soo grateful.
