Abiotic and Biotic Factors S-cool, the revision website

Soil pH and mineral content: plants need mineral ions like nitrates to grow. Where they are limited in the soil, plants struggle to grow - unless they get them by trapping animals and digesting the minerals from their decaying bodies. Low pH in soil slows down the rate of decay, and therefore slows down the relase of mineral ions back into the soil. This inhibits new plant growth.

GCSE Diffusion Revise Membranes and Exchange Surfaces

A plant also needs water and mineral ions. These are absorbed from the soil by osmosis (water) and active transport (mineral ions) via specialised cells called root hair cells . In animals, the common examples of exchange surfaces are in the lungs (where gaseous exchange takes place across the alveoli) and in the small intestine (where nutrients are absorbed into the bloodstream via the villi ).

How Water Moves Through Plants Sciencing

Plant roots reach into the soil and seek water and minerals for the plant to grow. Once the roots find water, the water travels up through the plant all the way to its leaves. The plant structure used for this water movement in plants from root to leaf is called xylem.
