Describe the process of transpiration, from

the time H20 enters a plant through the
roots to when H20 leaves a plant.

it's like a humidifier

it's like a water going up a pipe in building

& drying on the roof

Water enters the plant

through the roots by

osmosis

osmosis is sort of like

1. water going thru a strainer on a really small or microscopic level

2. from a wet area to a dry area

in transpiration

water goes from the soil which is wet

to a dry area the roots

root's dryness acts like a water magnet

water goes up the stem &

into the leaves through

xylem vessels

xylem are like veins & arteries of plants

xylem are long, hollow tubes that send

water & minerals

from the roots

up to the rest of the plant

when water gets the leaves,

it evaporates & turns into water vapor.

this is called

"evapotranspiration"

a combination

transpiration & evaporation

water vapor diffuses out of the leaves

through small openings called

STOMATA

STOMATA are tiny holes under the leaves

movement of water

out of the stomata

creates a negative pressure gradient

or a water magnet like effect

that pulls more water up

from the roots

through the xylem vessels

The water that leaves the plant through transpiration helps to regulate the temperature of the plant, transport nutrients and minerals, and provide the necessary moisture for photosynthesis.

The process of transpiration is influenced by environmental factors such as temperature, humidity, and wind, as well as by the physiology of the plant itself.

So, in summary, transpiration is a crucial process in the life of a plant as it helps it to obtain and circulate water and nutrients throughout the plant, while also regulating its internal temperature.
