ORGANIZATION OF LIFE
ORGANIZATION OF LIFE
A. COMPETENCE STANDARD
TO UNDERSTAND THE DIVERSITY OF LIVING THINGS
B. BASIC COMPETENCE
TO DESCRIBE THE DIVERSITY OF LIFE SYSTEM FROM CELLS TO ORGANISM LEVEL
C. OBJECTEVES:
AFTER TEACHING AND LEARNING PROSES , THE STUDENTS ARE ABLE TO :
1.Explain the differences and similarities between cell, tissue, organ, organ system and organism.
2.Observe the plant and animals tissue.
3. Explain the function of muscle tissue in human.
Material
1. Cell
A cell is the basic unit of all living things. It is the smallest part of a living thing which is fully alive.
The Basic Parts of Cell:
1. Cell Membrane
2. Cytoplasm
3. Nucleus

PLANT CELL AND ANIMAL CELL[Photo]
THE PARTS OF THE CELL:
A. CELL WALL
THE FUNCTION IS TO PROTECT THE CELL
B. MEMBRANE PLASMA
THE FUNCTION IS TO PROTECT THE CONTENT OF THE CELL
C. NUCLEUS
NUCLEUS CONTROLS ALL CELL ACTIVITIES AND CONTAINED CHROMOSOMES
D.CYTOPLASM
- IT HAS A GEL-LIKE FORM (THICK)
- ALL ORGANELLE CAN BE FOUND IN CYTOPLASM
E. MITOCHONDRIA
THE FUNCTION IS TO PRODUCE ENERGY OF THE CELL
F. ENDOPLASMIC RETICULUM (ER)
SMOOTH ER
- LACK RIBOSOMES
- SYNTHESIS OF LIPIDS
ROUGH ER
- STUDDED WITH RIBOSOMES
- SYNTHESIS OF PROTEINS
G. LYSOSOMES
THE FUNCTION IS TO DIGEST THE PART OF BROKEN OR OLD CELL. THIS PROCESS WILL RENEW THE CELL.
H. CHLOROPLAST
CHLOROPLAST IS AN ORGANEL THAN CAN ONLY BE FOUND IN PLANT CELL.
INSIDE A CHLOROPLAST THERE IS CHLOROPHYLL.
CHLOROPHYLL CAPTURES LIGHT ENERGY AND CONVERTS IT TO CHEMICAL ENERGY
I. VACUOLE
VACUOLE STORES FOOD AND OTHER CHEMICAL MATERIAL PLANT WILL WILTS IF VACUOLE IS NOT FILLED WITH WATER.
DISTINGUISH AN ANIMAL CELL FROM A PLANT CELL
THE PART OF THE CELL ANIMAL PLANT
VACUOLE NO YES
CENTIOLES YES NO
CELL WALLS NO YES
CHLOROPLAS NO YES
2. TISSUE
Tissue is a group of cells that having the same shape, structure and function.
EXAMPLE:
PLANT TISSUE:
EPIDERMIS, PHLOEM AND XYLEM TISSUE

3. ORGAN
An organ is a group of tissue that together have the function to support a duty.
EXAMPLES:
HEART ORGAN

4. ORGAN SISTEM
Is several organs that cooperate to do a certain work function.
EXAMPLES:
THE TRASPOTATION SYSTEM

THE REPRODUCTION SYSTEM [Photo]
THE EXCRETORY SYSTEM[Photo]
THE NERVOUS SYSTEM

5. ORGANISM
Many organ systems that are connected to each other and work together to support a certain function will compose an individual of organism.
EXAMPLES:

ORGANIZATION OF LIFE:
CELL --> TISSUE --> ORGAN --> ORGAN SYSTEM --> ORGANISM
