Neutrophils are key players in the innate immune response, primarily responsible for phagocytosing and destroying invading pathogens.

Parenchyma cells primarily function in storage, as they can store starch, oils, and water.

PCR is used to amplify specific DNA sequences, making millions of copies of a particular segment.

Phloem is responsible for the transport of sugars and other metabolic products downward from the leaves.

Phloem is responsible for the transport of sugars and nutrients produced during photosynthesis from the leaves to other parts of the plant.

Phytosterols help lower cholesterol levels in humans by competing with cholesterol absorption.

Probiotics are beneficial bacteria that help maintain a healthy gut microbiome and enhance digestion.

Red blood cells are primarily responsible for transporting oxygen from the lungs to the body's tissues.

The primary function of red blood cells is to transport oxygen from the lungs to the body's tissues.

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

RNA polymerase synthesizes RNA by using a DNA template during the process of transcription.

Root hairs increase the surface area for water and nutrient absorption from the soil.

Stomata are small openings on the leaf surface that allow for gas exchange, primarily oxygen and carbon dioxide.

Stomata facilitate gas exchange, allowing carbon dioxide in and oxygen out.

T helper cells play a crucial role in the immune response by activating B cells to produce antibodies and cytotoxic T cells to kill infected cells.

The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs.

The primary function of the Calvin cycle is to fix carbon dioxide into organic molecules.

The cambium is responsible for secondary growth, allowing plants to increase in thickness.

Chloroplasts are the organelles responsible for photosynthesis, converting light energy into chemical energy.

The primary function of the circulatory system is to transport oxygen and nutrients to cells and remove waste products.

The primary function of the circulatory system is to transport nutrients and oxygen to cells and remove waste products.

The complement system enhances the ability of antibodies and phagocytic cells to clear pathogens from an organism, primarily through opsonization and lysis.

The complement system enhances phagocytosis through opsonization and can directly lyse pathogens via the formation of the membrane attack complex.

The coronary arteries supply oxygenated blood to the heart muscle itself, ensuring it receives the nutrients needed for contraction.

The corpus luteum primarily produces progesterone, which helps maintain the uterine lining during early pregnancy.

The epiglottis is a flap that covers the trachea during swallowing, preventing food and liquids from entering the airway.

The primary function of the excretory system is to remove waste products from the body, maintaining homeostasis.

The exoskeleton in arthropods provides support and protection, allowing them to maintain their shape and protect against predators.

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

The light reactions convert solar energy into chemical energy in the form of ATP and NADPH.
