COME ON!! LET US NOW LEARN ABOUT THE SAPROPHYTIC MODE OF NUTRITION IN PLANTS WHICH ARE PRESENT IN OUR ENVIRONMENT.

SAPROTRYPHIC
MODE OF
NUTRITION

2. What is meant by Saprotryphic
Mode of Nutrition?
⮚ Saprophytic Mode of
Nutrition is that nutrition
in which an organism
obtains its food from
Decaying Organic Matter.
For Example - Dead Plants
, Animals, Rotten Bread etc.
⮚ Plants that use the
Saprotrophic mode of
nutrition are called
Saprotrophs .

3. IN BRIEF ......[The description of
SAPROPHYTES]
⮚'Sapros' refers to rotten and 'trophic' refers to
food.
⮚ Saprotrophic nutrition is the process by which
the Organisms feed on Dead and Decaying
Matter.
⮚ The food is digested outside the cells or even
the body of the organism - Extracellular
digestion.
⮚ The organism secretes digestive juices that
contain Enzymes directly on to the food. The
digestion makes the Food Soluble and it is then
Absorbed by the Organism.

4. Wow!
So beautiful plants .
I wonder why people
don’t plant them.
Hey!
First , you go near the
plants and smell them.
[AFTER
SMELLING]
Eww!
They are stinking.
Don’t you want to
know their role in
this Environment!
Yes, Of course!
So , Now we will learn their

5. THE IMPORTANCE OF
SAPROTRYPHIC PLANTS.
⚫The reason Saprophytes
are so beneficial to the
environment is that they
are the primary recyclers
of nutrients. They break
down organic matter so
that the nitrogen, carbon
and minerals it contains
can be put back into a
form that other living
organisms can take up
and use.

6. So , we know that animals
die everyday at many
places.
But!
If this is true , then why
don’t these plants grow
everywhere?
Ya!
This is true that
animals die everyday at
many places.
But!
These plants do not
grow at all the places
where animals die
BECAUSE
There are some
conditions in which
these plants can grow.
So , Now we will learn about the
conditions in which SAPROPHYTIC
PLANTS can grow.

7. CONDITIONS IN WHICH
SAPROTRYPHIC PLANTS CAN
GROW.
⮚In order for a saprotrophic organism to facilitate
optimal growth and repair, favourable conditions and
nutrients must be present . Optimal conditions refers to
several conditions which optimise the growth of
saprotrophic organisms, such as:-
⮚Presence of water: 80–90% of the fungus is composed of
water by mass, and requires excess water for absorption
due to the evaporation of internally regent water.
⮚Presence of oxygen: Very few saprotrophic organisms
can endure anaerobic conditions as evidenced by their
growth above media such as water or soil.

8. CONTINUED.........
⮚Neutral-acidic pH: The condition of neutral or mildly
acidic conditions under pH 7 are required.
⮚Low-medium temperature: The majority of saprotrophic
organisms require temperatures between 1 °C and 35 °C,
with optimum growth occurring at 25 °C.
