1 . Discuss why flowering plants produce flowers and fruits . Describe how a tree moves

water from the ground to every leaf . Why do plants need to `breathe Flowering plants produce flowers and fruits as this is their safeguard for the continuance

of their species amidst the ever changing environmental conditions According to Sean

Carrington (2005 , flowering plants was described by Charles Darwin as that abominable

mystery (1st par ) and as such are the dominant plants on earth today with over a quarter

million species

It is a

known fact that water cannot run uphill but can climb walls trough capillary action

Water can be pulled however by suction up to a height of not more than 30 feet (Summers

2005 . But trees can move up water from the ground and distribute it to all and every leaves

it has . Summers (2005 ) revealed that in the woody portion of trees called xylem are array of

narrow tubes that are responsible for carrying up water from roots to the leaves . The author

added that at the top of every xylem tubes , the water evaporates into spaces under the leaves

and exit to the atmosphere through natural openings in the leaves called stomata . The

process of evaporation of water through the stomata is termed as transpiration . The latter

creates a capillary action which is the electrostatic attraction between the water and the leaf

cells and the inner surface of the xylem tubes that sucks the water through the xylem vessels

and distribute it...
