Diffusion happens when there is a difference in concentration. So for water to diffuse out of the cell, the concentration of water has to be lower outside the cell, than inside the cell.

Geologists have divided the earth history into time units that are largely based on the earth's biotic composition. The modern geological time scale includes both relative and absolute age dating and represents the most up-to-date assessment of the earth's history.
In the modern geological time scale, the eras in earth's history when the planet was populated with advanced life forms are referred to as the Paleozoic (meaning ancient life), the Mesozoic (meaning middle life), and the Cenozoic (meaning recent life).
Answer:
A plant takes in carbon dioxide ( CO2 ) and water ( H2O ) and comes out with oxygen ( O2 ) and sugar/glucose ( C6H12O6 ). But Whats the science behind it all?
Explanation:
Once we humans breath out carbon dioxide, the plants open the pores in their leaves to take it in and to obtain water, the plants absorb water and nutrients through the xylem: a tissue made up of thin tubes located just below the surface of the plant's stems. The molecules in this tissue attract water molecules from the soil, so that the water is pulled upwards. This process is called capillary action. Some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. The green leaves of plants carry out both photosynthesis (in light) and respiration (all the time). Photosynthesis uses carbon dioxide to make sugar and produces oxygen as a byproduct. Respiration uses oxygen to release energy from stored sugar and produces carbon dioxide as a byproduct.
