CURRICULAR STATEMENT
By observation, discussion, communication and drawing the children learn about the nutrition in
amoeba
Terms :
Facts :
Content analysis
 Microorganisms, protoplasm, pseudo podia, food
vacuole, lysosome, nucleus, contractile vacuole,
Endocytosis.
 Amoebas food is micro organisms and particles
of organic waste in the water.
 When an amoeba comes in contract with its prey,
the protoplasm flows over it.
 So amoeba engulfs it in a cavity or a small
pocket is formed in which the prey slips in.
 It is enclosed by the pseudopodia.
 The pocket is closed and pinched off as a cavity
which forms the food vacuole.
 The food vacuoles serve as a temporary stomach
for an amoeba.
 The surrounding protoplasm secrete digestive
fluids.
 It is stored in the lysosome.
 A lysosome full of enzymes fuse with each food
vacuole
 The enzyme gradually digests the food.
 Digestion is completed in 15-30 hours.
 The soluble foods resulting from digestion
diffuse through the membrane of the food
vacuole in to the surrounding cytoplasm.
 Absorption proceeds, food- vacuoles decreases in
size, till only the indigestible matter is left in
them.
 The elimination of the indigestible food also
occurs at any point on the surface of the body as

2. Concept
Learning out comes in the terms of specification
there is no regular anus.
 Amoeba absorbs food by endocytosis through
cell membrane.
 The sugars, glycerin and fathy acids are used as
sources of energy.
 Amoeba is a unicellular organism. Amoeba
enclosed by the pseudopodia so that the pocket is
closed and pinched off as a cavity which forms
the food vacuole.
Enable the pupils to acquire the following ideas
 Factual knowledge about nutrition in amoeba
1. Recalling new term like micro organism,
pseudopodia, protoplasm, food vacuole,
lysosome, nucleus, contractile vacuole,
endocyotosis.
2. Recognizing the specialties of nutrition in
amoeba.
3. Explaining the nutrition in amoeba.
 Conceptual knowledge about nutrition in amoeba
1. Recalling the peculiasches of nutrition in
amoeba.
2. Comparing the digestion of organism
with higher order animals.
 Procedural knowledge on nutrition in amoeba
1. Executing method to identify the nutrition
in amoeba.
 Met cognition knowledge on nutrition in amoeba.
1. Recognizing the factors influencing
the nutrition in amoeba.
2. Implementing the techniques to
observe the digestion of amoeba.
 Scientific attitude towards the nutrition on
amoeba.
1. Locomotary organ like pseudopodia
are responsible for gathering food.
 Collects more information about nutrition in
amoeba process skill like

Group discussion lead by the teacher
The food is enclosed by the pseudopodia so that the pocket is
closed and pinched off as a cavity which forms of food
vacuole. The vacuole serves as a temporary stomach for an
amoeba. The surrounding protoplasm secrets digestive fluids
and it is stored in the lysosome. A lyso
lysosome full of enzymes
fuses with each food vacuoles. The enzyme gradually digests
with food. Digestion is get completed in 15
15-30 hours.
