class and Protozoa phylum? Now, we will learn about one of the organism that from

Rhizopoda class.d. To arrive or tell the basic competent, indicator, and goal lesson.e. To divide the students

Example of instrument

Written test :

1. Mention the characteristic of Amoeba!

2. Explain the body structure of Amoeba!

3. Explain the reproduction of Amoeba!

The key :

1. The characteristics of Amoeba

a. Amoeba is included in the class of the phylum Protozoa and

Rhizopoda class

b. Amoeba is unicellular organism

c. Body shape is always changing (Amoeboid)

d. Moves using artificial legs or widening cells known as

pseudopodia

e. Free-living, soil or organic substances containing aqueous

f. Reproduce by dividing (binary fission)

2. The body structure of Amoeba

Ectoplasm, which is a clear cytoplasm and found near the cell

membrane (outer).

Endoplasmic, namely a clear cytoplasm and in the next of

ectoplasm. Ectoplasm and endoplasmic role in the movement of

the Amoeba. The change of moisture content on one side of the

body causing Amoeba pseudopodia formed cytoplasm flow.

Amoeba with pseudopodia movement called amoeboid motion.

These organelles contained endoplasmic performance which are :

a. Cell nucleus (serves to regulate all activities that take place in

the cell).

b. Food vacuoles (to digest food, food that is not issued through

the contractile vacuole digested).

c. Contractile vacuole (to regulate water levels in the cytoplasm

or as osmoregulator set the cell osmotic pressure is always

higher then the osmotic pressure in the surroundings, and as a

means of excretion of the waste in the form liquid).

d. The cell membrane that serves to :

As a protective cell nucleus

Regulating the exchange of substances

Tool movement

To capture the external stimuli

3. The reproduction of Amoeba

Amoeba reproduce by dividing, by cleavage of Bine. In the binary

fission, a stem cell will become two new cells. Longitudinal binary

fission begins with Amoeba cell nucleus. Further dividing cell

nucleus and cytoplasm followed by division into two parts. Finally,

the resulting two new Amoeba cells that have the same shape and

properties.

1. Make the picture of Amoeba with the main caption!

2. Explain the digestion of Amoeba with its picture!

3. Explain the excretion of Amoeba !

The key

1. The picture of Amoeba with the main caption

2. The digestion of Amoeba with its picture

In the first Amoeba digestion of food picked up by the phagocytic Amoeba cells made

with pseudopodia. Then pseudopodia surrounding food molecules to be captured. Once

confined to food, the Amoeba plasma membrane directly in contact with food will form a

food vacuole. Then the food is digested in food vacuoles.

3. The excretion of Amoeba

Gas exchange at Amoeba last through the entire body surface. Where oxygen diffuses

into the cell through the cell membrane Amoeba. Then the oxygen in the cytoplasm is

used the oxidize nutrients, produce energy, and carbon dioxide. Carbon dioxide is then

released from the through the plasma membrane.
