Osmosis And Plant Stuff

Osmosis

"Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration."

Well... that was easy... So if there's lots of it in one place, it goes to where there is less! Like a pimp.

The Ladies be flocking.

Active Transport

The process of root hairs absorbing minerals from the soil. ODD thing to remember. Active transport uses energy from respiration to help pull minerals into the root hairs. Confusing heh? Well, this is because it is normally a lower concentration of minerals in the soil compared to the root hairs. So would diffusion work? Of course not! Along comes active transport with it's cheeky respiration energy.

Cheeky Bugger...

Transpiration

Final bit on this! Simple definition:

"Transpiration is the Loss of Water from the plant"

The water loses it through the water evaporating from the leaves. The leaves are adapted for this due to stomata. Looks like they've been doing their homework... If you're here I guess you haven't.

Look! Even 4 year olds' understand it.
