2. Process whereby plants use
CO2, water and light energy
in a series of chemical
reactions to produce
glucose.
Definition: Photosynthesis

3. Requirements: Sunlight

4. Requirements: CO2

7. Product: Glucose

8. Product: Oxygen

10. CO2
Gaseous exchange
absorption and
emission
of gases. O2
Found mainly on the leaves

15. Growth

16. Some of the glucose is converted to
cellulose which makes the cell walls.
Extra glucose is stored as starch
(insoluble in water) which is a food
source for other living organisms.

17. Green plants are autotrophs.
Autotrhophic plants make their
own food.

18. Plants that cannot make their own
food, need to get it by other means:

19. Saprophytes are
plants that
survive on dead
organic tissue.
Parasites
obtain its
nutrients from
its host. This
hurts the host.
