5. The Leaf
Two Functions of the Leaf:
Photosynthesis is the process when
leaf cells containing chlorophyll take in
carbon dioxide and water and using
sunlight, make sugar and oxygen.
Transpiration is the loss of water from
the leaf. This helps to draw water up
through the plant from the roots.

7. The Stem:
The stem has vessels that
transport sap and water
throughout the plant.
Sap is a nutrient-rich fluid that
contains a lot of sugar.

9. The Root
The root is the part of the plant that
takes in water and minerals for the
plant.
Roots have root hairs that increase
the surface area for more water
absorption.

11. The Flowers
The sole function of the flower, which is
generally the showiest part of the plant, is
sexual reproduction. Its attractiveness and
fragrance have not evolved to please man
but to ensure the continuance of the plant
species.
