Nutrition In Plants
Living Organisms are called non mortile.
We get nuterients from food.
Co2 is Carbondioxide and O2 is Oxygen and N2 is Nitrogen.
Nutrients
Carbohydrates Fats Proteins Vitamins & Minerals Roughage/Fibre
(energy) (energy) (Maintain or repair) (protective food) (proper digesion)
Proteins are also called Body Building Food.
⦁ Modes of Nutrition i.e. Types of nutrition
Types Of Nutrition
Autotrophic Nutrition Heterotrophic Nutrition
(auto:self, trophic:nourishment) (Hetero:others, trophic:nutrition)

their food. Only Green Plants are called Such animals are called Heterotrophs.
Autotrophs. Example – Human Beings, fungi,
animals, non green plants.
Autotrophic Nutrition
Photo- Light (sunlight), Synthesis- to combine (to prepare)
What Is Photo Synthesis?
It is the process by which green plants prepare their own food by using carbon dioxide and water in the presence of sunlight And Chlorophyll.
Carbondioxide + Water are Reactants i.e. Raw.
Plants get Co2 through Atmosphere & O2 is released in atmosphere.
Just As we need heat to cook food the sun light gives heat to react Co2 and water together and in same way chlorophyll helps in storing the sunlight’s heat.
When the plant store carbohydrates they form starch.
Plants —->Proteins —-> Growth. Plants make proteins with Nitrogen. The way the Guard Cell expands or shrink decides the size of stomata/stomatal opening.
Plants get proteins through Nitrogen.
The bacteria helps in purifying Nitrogen that is usable for plants.
Specially suffered by leguminous plants (pulses). N2 cant be used directly by plants so bacteria called rhizobium helps in making N2 to a usable form.
Non leguminous plants don’t have Bactria they get N2 by fertilizers provided by the farmer.
Cell is the basic material for life.
Heterotrophic Nutrition ( Non Green Plants)
Parasitic Nutrition
It is the mode of nutrition in which an organisms of its valuable nutrients.
Parasite Take Nutrients While Host Gives Nutrients.
A is The Host And B Is The Parasite.
Insectivores Plants
Have chlorophyll -> Green -> Photosynthesis
For plants that grow in soil with no nitrogen.
a pitcher releases sweet smell that attracts the insect. As the insect moves the lid closes because of imbalance of plant.After the insect is trapped the walls of pitcher releases digestive juices that converts the insect into liquid form full of nitrogen. The juice is moved to all parts of plant while the dead body is make manure in soil.
Saprotrophic Nutrition
In this mode of nutrition an organism feeds on dead and decayed organic matter in solution from their surroundings . Such as Fungus, Mushroom, Bread Mould.
the mushroom sends strong digestive juices that converts the decayed matter into liquid form used for growth of mushroom. The mushroom sucks the juice required for its growth.
Symbiotic Relationship
in this mode of nutrition 2 organisms get profit while only one works.
Eg – Lichens
Here in Fungus Chlorophyll is absent and in Alga Chlorophyll is present.
