Nutrition in Plants
• Nutrition: Intake of food and its utilization by the
body to produce energy
• P2N: Every living organism needs food to
survive but the way they get their food is different
• 2 main ways:
• Autotrophic Nutrition
• Heterotrophic Nutrition
• Autotrophic Nutrition: The mode of nutrition in
which organisms make their own food is called
Autotrophic mode of nutrition. The organisms that
follow this type of nutrition are called Autotrophs.
E.g. Plants, etc
• Heterotrophic Nutrition: The mode of nutrition in
which organisms can’t make their own food is
called Heterotrophic mode of nutrition. They are
, depended on other organism for food. The
organisms that follow this type of Nutrition are
called Heterotrophs.E.g humans, some animals.
• Decomposers: They are group of heterotrophs
that get their energy by breaking down the
remains of dead animals or waste products of
these animals. They are referred as recyclers as
they prevent the buildup of dead matter and they
recycle it back in to the soil. E.g. Mushrooms,
other fungi, insects, some bacteria, etc.
• Auto-Trophs=Self-Nourishment
• Hetero-Trophs=Different-Nourishment
• How Plants Make Their
Own Food?
• Ingredients
• Sunlight (Absorbed Only by the Green Parts Because of Chlorophyll)
• CO2 (Reached Through Small Pores Called Stomata That Are Present in
the Leaf)
• H2O (Absorbed by the Roots)
• Only green parts of the Plant are able to make food
because they have a green pigment called chlorophyll
it is why they have green color, and they can absorb
sunlight. Chlorophyll absorbs Water and Carbon
Dioxide in the Presence of Sunlight to Produce
