Explanation:

Osmosis is a biological phenomenon whereby the molecules of a solvent moves through a selective permeable membrane from an area of low solute concentration to an area of high solute concentration.

There are three types of osmotic solutions viz;

Isotonic; which has an equal solute concentration

Hypotonic; which has a lower solute concentration

Hypertonic; which has a higher solute concentration

When a living cell is placed in a solution, the solvent molecule (which is usually water) moves in or out of the cell depending on whether the cell has a higher solute concentration (hypertonic) or lower solute concentration (hypotonic) in comparison with the solution it was immersed in.

A good example can be observed in the absorption of water by the root hairs of plants; root hairs, due to the accumulation of minerals, possess a lesser concentration of water molecules than the soil i.e the root hairs are hypertonic. Due to this osmotic gradient, water (solvent) moves from the SOIL, which has a lower concentration of solute, to the ROOT, which has a higher concentration of solute.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
