BIOLOGI : IS THE STUDY OF ORGANISM ( ALL LIVING ASPECTS)

BIOCHEMISTRY is the study of structure & process of chemistry in a life organism

BIOLOGI SEL IS THE STUDY OF Cells are the basic units of life and all the chemical reactions of life occur in cells

ORGANISMORGANISM

LIFE FUNCTIONS : 1. REPRODUCTION/REPLICATION 2. HEREDITER OF TRAITS 3. GROWTH 4. METABOLISM FOR ENERGY 5. HOMEOSTASIS 6. TRANSPORTS 7. COMMUNICATION BETWEEN CELLS.

BASE ON ENERGY SOURCES, ORGANISM :BASE ON ENERGY SOURCES, ORGANISM :

AUTOTROPHIC :

Organism need INORGANIC Compound (CO2, H2O, NH3) for energy synthezising.

HETEROTROPHIC : Organism need ORGANIC (CARBON) for

their life. They can not synthezise all biomoleculs.

MODERN CELL THEORYMODERN CELL THEORY

1. All living things are made of one or more cells

2. Cells are the basic units of life and all the chemical reactions of life occur in cells

3. All cells arise from preexisting cells

Cell RequirementsCell Requirements

1. take in materials2. extract useful energy 3. make their own molecules 4. grow in an organized manner5. respond to stimuli6. reproduce themselves7. Plasma membrane to maintain

integrity

Prokaryotes Prokaryotes vsvs EukaryotesEukaryotes All Bacteria No membrane bound

organelles No microtubules flagella are single

filaments single circular DNA

molecule (not associated w/histone proteins).

No true sexual reproduction

Defined nucleus DNA stored as

chromosomes (w/ histone proteins)

Chromosomes regularly divide by Mitosis

Flagella & cilia have 9-plus-2 pattern of microtubules
