Transpiration pull, created by the evaporation of water from the leaves, is the main driving force for water movement in plants.

Transpiration pull, created by the evaporation of water from the leaf surface, is the main driving force for water movement in the xylem.

Transpiration pull, created by the evaporation of water from the leaves, is the main driving force for water movement in xylem.

Deforestation leads to habitat loss, which is a major threat to biodiversity.

Deforestation leads to the loss of habitat for many species, resulting in decreased biodiversity.

Adenosine triphosphate (ATP) is the main energy source for muscle contraction.

Plastic waste poses multiple environmental concerns, including air pollution from incineration, soil degradation, and water contamination.

Pepsin is the main enzyme that digests proteins in the acidic environment of the stomach.

Uric acid is the main excretory product of purine metabolism in humans.

Climate is the main factor that determines the type of ecosystem, influencing temperature and precipitation patterns.

The strong nuclear force is the primary force that holds the nucleons (protons and neutrons) together in the nucleus.

The main function of a transformer is to increase or decrease the voltage in an AC circuit.

The main function of a transistor is to amplify electrical signals.

Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs, making them essential for respiration.

Antibodies are proteins produced by the immune system to identify and neutralize pathogens such as bacteria and viruses.

Cartilage provides support and flexibility to various structures in the body, such as joints and the rib cage.

Decomposers recycle nutrients by breaking down dead organic matter, returning essential nutrients to the soil.

Ligaments connect bone to bone, providing stability to joints.

Lipids serve as a major form of energy storage in the body.

Phloem is responsible for the transport of food (sugars) produced during photosynthesis from leaves to other parts of the plant.

Plasma is the liquid component of blood that carries nutrients, hormones, and waste products throughout the body.

Producers, such as plants, produce energy through photosynthesis, forming the base of the food chain.

Sepals protect the flower bud before it opens.

Skeletal muscle tissue is responsible for voluntary movements of the body, allowing for locomotion and manipulation.

Stratified squamous epithelium primarily functions in protection against abrasion and pathogens.

Surfactant reduces surface tension in the alveoli, preventing their collapse and making it easier for the lungs to expand during inhalation.

The anther is the part of the stamen that produces and contains pollen grains.

The cell wall provides protection and structural support to plant cells, maintaining their shape.

Gastric acid activates digestive enzymes, particularly pepsinogen to pepsin, and helps in protein digestion.

Gastric juice contains hydrochloric acid and pepsin, which are essential for the digestion of proteins.
