Summarize the following text to main points and sub-points and make detailed explain for them:

The main points are:
1. Science, biology and biologist definition and general concepts.
2. Branches of biology such as ecology, botany, zoology, microbiology, taxonomy, genetics, molecular biology, morphology, ethology, physiology, embryology, and cell biology.
3. Cellular composition, unicellular and multicellular organisms.
4. Characteristics of living things such as growth, development, material and energy use, responding to the environment, maintaining internal balance, movement, reproduction, and genetic code. 

Sub-points:
1. Cell structure and function 
2. Types of organisms (unicellular, multicellular)
3. Organisms growth and development
4. Energy and material usage
5. Environmental response and stimuli 
6. Maintaining homeostasis
7. Types of movement (place to place, internal, external part)
8. Sexual and asexual reproduction
9. Genetic code inheritance
10. Evolution and adaptation ### Summary of Key Points and Subpoints

1. **Water Balance Inside and Outside the Cell**
   - Importance of maintaining water balance for cell function.

2. **Human Body Temperature**
   - Optimal temperature range for cellular functions.

3. **Cell Functionality**
   - Cells operate best when internal and external conditions are balanced.

4. **Movement Types**
   - **Place to Place**: Movement of organisms (e.g., bears running, birds flying).
   - **External Part**: Plants orienting leaves towards sunlight (phototropism).
   - **Internal**: Cytoplasmic streaming within cells.

5. **Reproduction**
   - **Sexual Reproduction**: Involves two parents; combines genetic material to form a new organism.
   - **Asexual Reproduction**: Involves one parent; a single cell divides to form two (e.g., bacteria).

6. **Genetic Code**
   - Offspring inherit traits from parents through DNA, which carries genetic instructions.

7. **Evolution and Adaptation**
   - Organisms change over time to adapt to environmental needs.
   - Examples of adaptations:
     - **Behavioral**: Bird migration.
     - **Physiological**: Human body temperature regulation, hibernation.
     - **Structural**: Differences in ear length of hares in different environments.

8. **Classification and Taxonomy**
   - **Classification**: Grouping organisms based on similarities.
   - **Taxonomy**: Science of classifying organisms based on evolutionary relationships.
   - **Early Taxonomic Systems**: Aristotle's and Linnaeus's contributions to biological classification.

9. **Taxonomic Categories**
   - Hierarchical structure: Kingdom, Phylum, Class, Order, Family, Genus, Species.

10. **Five Kingdoms of Living Organisms**
    - **Monera**: Prokaryotic, single-celled organisms.
    - **Protista**: Eukaryotic, mostly unicellular organisms.
    - **Fungi**: Eukaryotic, heterotrophic organisms with chitin cell walls.
    - **Plantae**: Eukaryotic, autotrophic, multicellular organisms.
    - **Animalia**: Eukaryotic, multicellular, motile organisms.

11. **Chemistry of Life**
    - **Atoms**: Basic units of matter.
    - **Molecules**: Substances with تم إنشاؤه بواسطة BLACKBOX.AI، جرب الدردشة غير المحدودة https://www.blackbox.ai وبالنسبة لطلبات API، استبدل https://www.blackbox.ai بـ https://api.blackbox.ai Model not found or too long input.
