NUTRIENTS

4. MODES OF NUTRITION IN PLANTS
AUTOTROPHIC
MODE OF
NUTRITION
HETEROTROPHIC
MODE OF
NUTRITION
AUTO = SELF
TROPHS= NOURISHMENTS
HETERO = OTHERS
TROPHS= NOURISHMENTS

5. AUTOTROPHIC MODE OF NUTRITION
Photo = light
Synthesis= to combine

6. AUTOTROPHIC MODE OF NUTRITION
AUTOTROPHS= Green
plants can prepare food for
themselves
Autotrophic mode of nutrition = Organism that
prepares its own food

7. HETEROTROPHIC MODE OF NUTRITION
Heterotrophic mode of nutrition = Plants which
cannot produce their own food, depend on other
green plants.
Parasitic
Saprotrophic
Symbiotic
Insectivorous

8. PARASITIC NUTRITION
Cuscuta
(Amarbel)
Host

9. EXAMPLES OF PARASITIC PLANTS ARE AS FOLLOWS
Rafflesia

10. SAPROPHYTIC NUTRITION
Organism which has
saprotrophic nutrition
are called
saprotrophs.
(Example:)
Bread mould

11. RECAP
• What is the end product of the
photosynthesis process?
• Give 2 examples of parasitic plants.
• What are the four kinds of
heterotrophic plants?
