What is
Protoplasm ?
Where is it ?

5. DEFINITION
Protoplasm is the living
contents in a cell that is
surrounded by a plasma
membrane.
Protoplasm
Proto = First
Plasm = Substance
Protoplasm is devied in two
form :
1. Liquid  Sol
2. Jelly  Gel
*Depends on physiological state
Protoplasm is devied in two presence
:
1. Cytoplasm
2. Nucleoplasm

6. PROTOPLASM
• Present between the nucleus and the
plasma membrane of a eukaryotic cell
• Within the cytoplasm of a eukaryotic cell,
suspended in cytosol, are a variety of
organelles of specialized form and
function.
Cytoplasm
• Enveloped by the nuclear membrane or
nuclear envelope
• The nucleoplasm is a highly viscous liquid
that surrounds the chromosomes and
nucleoli
• Many substances such as nucleotides and
enzymes are dissolved there.
• The soluble, liquid portion of the
nucleoplasm is called the nuclear
hyaloplasm.

polypeptides

19. Amino Acid
- Are organic molecules possessing both
carboxyl and amino groups

21. Lipid

hydrophobic molecules
• Lipids
– Are the one class of large biological
molecules that do not consist of
polymers
– Share the common trait of being
hydrophobic

22. Fats
– Are constructed from two types of smaller molecules, a
single glycerol and usually three fatty acids
– Vary in the length and number and locations of double
bonds they contain

23. Fats
• Are constructed from two types of smaller molecules,
a single glycerol and usually three fatty acids

24. Fats
• Saturated fatty acids
– Have the maximum number of hydrogen atoms
possible
– Have no double bonds

• Unsaturated fatty acids
– Have one or more double bonds

26. Phospholipids
• Phospholipids
– Have only two fatty acids
– Have a phosphate group instead of a third fatty
acid

– Results in a bilayer arrangement found in cell
membranes

29. Steroids
• Steroids
– Are lipids characterized by a carbon skeleton consisting
of four fused rings
• One steroid, cholesterol
– Is found in cell membranes
– Is a precursor for some hormones

30. Nucleic Acid
• Nucleic acids are composed of nucleotides to form long
polynucleotide chains.
– Each nucleotide is composed of 3 smaller units:
• 5-carbon sugar (deoxyribose or ribose).
• Phosphate group attached to one end of sugar.
• Nitrogenous base attached to other end of sugar.

31. Nucleic Acid
• The “backbone” of the nucleic acid is formed by the sugar and
phosphate pairs.
• The “rungs” are formed by paired nitrogenous bases.
– Nitrogenous bases complementary pair
• A + T (U)
• C + G..

32. Nucleic Acid
• There are two types of nucleic acids
– Deoxyribonucleic acid (DNA)
– Ribonucleic acid (RNA)

42. PHYSICAL PROPERTIES
• Protoplasm consists of various types of elements and organic and inorganic compounds
are heterogeneous.The sizes of particles are dissolved in the protoplasm ranged from
0.001 to 0.1 microns, so that it is a colloid solution
• Organic compounds that make up the matrix (protoplasm liquid) as karbohidarat,
proteins and fats in the form of suspension (size greater than 0.1 microns), while ions are
smaller than 0.001 microns in the form of a pure solution.

43. PHYSICAL PROPERTIES
• Brown motion, the motion of the molecules of protoplasm are irregular due to the
presence of water molecules.The motion was studied by Robert Brown (1827), an expert
on the Scottish nation Botany in a colloidal solution.Brownian motion is usually the case
in a colloidal solution and movement depends on the temperature and particle size.
• Colloidal solution on protoplasm can reflect light when the light comes right direction of
the colloidal system, incident light reflection is called theTyndall effect.
• Siklosis, the current form of movement that occurs in the protoplasm is in a state of sol.
This Siklosis caused by Hydrostatic Pressure,Temperature, pH, viscosity (viscosity), Age
of Sel.
• Ameboid motion, is the movement of protoplasm in the cells (especially animal cell:
Amoeba, Protozoa and leukocytes) are caused by changes in the function so that the
cytoplasm of elongated condition.
• Pressure surface, caused by the attraction of the molecules on the surface of the
