Study Notes

Plant Structure and Function

Sepals protect the developing flower and support the petals.
Stigma receives pollen during plant reproduction, crucial for fertilization.

Human Physiology

Haemoglobin's primary function is transporting oxygen in red blood cells.
Scurvy is primarily caused by a deficiency of vitamin C.
Collagen provides structure and strength to connective tissues in the body.
Roughage aids digestion and helps maintain gut health in the diet.

Nutritional Deficiencies

Vitamin D deficiency in children can lead to rickets, affecting bone development.
Anaemia is primarily caused by a lack of iron, resulting in decreased hemoglobin production.
A diet lacking essential nutrients is termed malnutrition.
Severe protein deficiency is known as kwashiorkor.
A lack of fiber in the diet may lead to constipation and digestive issues.

Blood Physiology

Blood platelets play a crucial role in clotting, preventing excessive bleeding.

Genetic and Health Risks

CDH gene mutations can result in increased risk for various health issues.

Cholesterol Management

Regular physical activity is likely to prevent cholesterol buildup in the body.

Respiratory and Circulatory Functions

Gas exchange is vital for providing oxygen to tissues and removing carbon dioxide.
Nutrients are transported to the heart via the blood through the circulatory system.
Cilia in the respiratory system help trap and expel foreign particles and pathogens.

A diet high in saturated fat can increase the risk of cardiovascular diseases.

Cell Biology

Mitosis primarily serves the role of growth and tissue repair through cell division.
Mitosis results in genetically identical daughter cells, maintaining genetic continuity.

Environmental Impact

Deforestation disrupts the carbon cycle by reducing the amount of carbon absorbed by trees.
The energy for photosynthesis primarily comes from sunlight.
Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.
Fossil fuels contribute to the carbon cycle by releasing stored carbon into the atmosphere when burned.
