Biology
Body Systems
Nervous System
Circulatory System
Digestive System
Endocrine System
Characteristic of living organism
M = Movement
R = Respiration
S = Sensitivity
G = Growth
R = Reproduction
E = Excretion
N = Nutrition
Fungi
Single cell
Some are Pathogens
Virus
Need host to reproduce
There is a protein coat around DNA
Virus is PATHOGEN
Pathogen
anything that causes a disease
All virus is pathogen
Only some fungi and bacteria
Plant
Multicellular
Have A ไม่มี
Do photosynthesis
Bacteria
Single cell
Have flagellum
Some can photosynthesis
Most obtain nutrient by feeding of other organism (ดูดพลังง่าย)
Animal
No cell wall, chlorophyll and vacuole
Multicellular
Carbohydrates in animal often form in glycogen
Parts of cells
ทุกอันเลย
Nucleus
Contain DNA
Control the cell มันสมอง
Mitochondria
Act as the power house ห้องเครื่อง
Cell wall
Only in P cell
Give cell extra support
Form its shape
can't be found in animal cell
Ribosome
produce protein
In P and A cell
Cytoplasm
Place where chemical reaction happen
Hold the cell together
Chloroplast
Contain chlorophyll and photosynthesis
Found in P cell
Vacuole
Only found in plant
Store food for P
Flagellum
Found in bacteria
For some cell to move
A tail of some cell
Level of Structure
Tissue
When cell form together เนื้อเยื่อ
Example: Muscle Tissue
Organ
Structure
EX: Heart
Cell
Cell is only one
EX: Plant cell
System
Lot of organ form to make body function
EX: Respiratory systen
Biological Molecules
Most molecule found in living organism fell to three groups
Hydrogen
Oxygen
Carbon
Protein
Made up of amino acid joining together
Protein =
3 Carbon
12 Hydrogen
6 Oxygen
4 Biomolecules
Lipids
Protein
Carbohydrates
Nucleic acid
Metabolism
Reaction that happen inside organism
Enzymes
Without it the reaction will go very slowly
Helps speed up chemical reaction
Each one is catalysts by specific enzyme
Almost all of the chemical reaction are controlled by enzymes
Enzyme
Movement inside and outside cells
Osmosis
Diffusion
When something move from a high to low concentration
Cell rely on diffusion such as:
Photosynthesis
Breathing
Any reaction that มีสิงที่เข้าไป
การเเพ่รกระจาย
EXAMPLE: Photosynthesis Alveoli Oxygen
