unit 4 : plants - transport of water in plants

The movement of particles from a region of higher concentration to a region of lower concentration through a semi-permeable membrane

The chemical process by which plants use sunlight, water and carbon dioxide to create oxygen and energy in the form of sugars

The inter molecular force between water molecules that creates a transpiration pull and keeps them together and stable so that the water molecules can be transported from the roots to the leaves.

The adhesion or attraction of water molecules to the walls of the xylem creating a transpiration pull that transports the water from the roots to the leaves

The process of a substance changing from liquid to gas or vapour

When the plant opens it's stomata, water on the surface of the spongy mesophyll cells evaporate and diffuse out of the leaf

The condition where the amount of water lost from the plant during transpiration is greater than the amount of water absorbed from the soil

Capillary action, transpiration pull and root pressure

Xylem and phloem

False, in phloem movement takes place in different directions

They are strengthed by lignin, which is an adaptation for the transport of water in the transpiration steam

Through osmosis which is a type of diffusion

Root hair cells —> Root cortex cell —> xylem —> leaf mesophyll cells

Carry water and minerals

Carry food down from leaf

A tissue which conducts water and minerals in plants

Magnesium and nitrates

☆They contain nitrogen to make proteins and amino acids

☆they are needed for cell growth

They make chlorophyll and are needed for photosynthesis
