Study Notes

Foreword

Science is important for the wellbeing of humans.
Science relies on exploration, inquiry, and investigation.
Science is often seen as complex and difficult, posing challenges for teaching to young learners.
It is important to make science learning engaging and link concepts to the real world.
The revision of science textbooks should align with global views of science and educational philosophies.
The curriculum should focus on developing scientific skills and fostering scientific literacy.

Animal Cell

The cell membrane is the outermost layer of the animal cell.
Cytoplasm is a semi-liquid substance that fills the cell.
Cell organelles are specialized structures within the cytoplasm.
The endoplasmic reticulum is a network of membranes that connects the plasma membrane and the nuclear membrane.
Mitochondria are organelles with double membranes.
Ribosomes are small organelles found in the cytoplasm or attached to the endoplasmic reticulum.
Golgi bodies are small vesicles near the nucleus.
The centrosome is a star-like structure near the nucleus found only in animal cells.
Vacuoles are large cavities filled with cell sap.

Nucleus

The nucleus is an oval-shaped organelle in the center of the cytoplasm.
It is surrounded by a double-layered nuclear membrane.
Nucleoplasm is a dense semi-fluid substance within the nucleus.
Nucleoli are small spherical bodies inside the nucleus.

Human as Organism

Health is a state of complete physical, mental, and social well-being.
Disease is an abnormal functioning of the body.
Diseases can be present from birth or acquired during life.
Communicable diseases are transmitted from one person to another.
Pathogens are disease-causing organisms.

Communicable Diseases

Bacteria are present in air, water, soil, and living and non-living things.
Bacteria cause many diseases, including:
- Tuberculosis

Health and Diseases

Scurvy can be prevented by eating oranges and lemons, suggesting it is caused by a nutritional deficiency.
The scapula is not the collar bone, the collar bone is the clavicle.
Respiration is the process of taking in oxygen and giving out carbon dioxide.
The spinal nerve arises from the spinal cord, not the brain.
Measles is caused by a virus, not Rhabdovirus.
A deficiency of iron causes anemia, not goitre.

Match the Following

BCG vaccine is used for treating tuberculosis.
The backbone is the main part of the skeleton that provides support to the ribs at the back.
Neurons are the smallest units of the nervous system that carry impulses.
Sperm is a special cell produced in the testes.
Alveoli are the terminal ends of the respiratory system.

Nutrients for Plants

Plants require nutrients for growth and development.
Nutrients are absorbed by plant roots from the soil.
Nutrients come from decayed plants and animals or fertilizers.
Plant nutrients are divided into macronutrients and micronutrients.
Macronutrients are required in large amounts.
Macronutrients are further divided into primary and secondary nutrients.
Primary nutrients are essential for plant growth.
The primary nutrients are nitrogen (N), phosphorus (P), and potassium (K).
