A fundamental theory in biology stating that all living organisms are composed of one or more cells, that cells are the basic unit of structure and function in living organisms, and that all cells arise from pre-existing cells.

The various processes that occur within a cell to maintain life, such as metabolism, growth, repair, and reproduction.

A thin, flexible layer that surrounds the cell, controlling what enters and exits the cell. It's selectively permeable.

An organelle involved in the processing, packaging, and transport of proteins and lipids within the cell.

Small, membrane-bound sacs that bud off from the Golgi apparatus, transporting processed molecules to other parts of the cell.

A network of protein filaments that provides structural support, helps with cell movement, and transports materials within the cell.

A small, membrane-bound sac that envelops and brings liquids into the cell through pinocytosis.

Organelles that synthesize proteins according to the instructions carried by mRNA.

A network of membranes studded with ribosomes that synthesizes and modifies proteins destined for secretion or other parts of the cell.

A network of membranes without ribosomes that synthesizes lipids, detoxifies drugs and poisons, and stores calcium ions.

Small, fluid-filled sacs that store water, nutrients, and waste within the cell.

A type of plastid in plant cells that stores starch, a form of carbohydrate.

A rigid outer layer found in plant cells that provides structural support and protection.

A type of crystal found in some plant cells, primarily for structural support.

A large, fluid-filled sac that stores water, nutrients, and waste in plant cells, maintaining turgor pressure.

A type of needle-shaped crystal found in some plant cells, which can be used for defense against herbivores.

Cells are small to maximize their surface area to volume ratio, which allows for efficient nutrient uptake and waste removal.

Cells divide for growth, repair, and reproduction. They make copies of themselves.

The process of cell division occurs in stages: Interphase (G1, S, G2), Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.

Cell division has three main functions: growth, repair, and reproduction.

Cancer is uncontrolled cell division caused by mutations in genes regulating cell growth. Mutations can arise from environmental factors or genetic predisposition.

A blood vessel that carries oxygenated blood away from the heart to the rest of the body.

The smallest blood vessel, where gas exchange occurs between blood and tissues.

A blood vessel that carries deoxygenated blood back to the heart from the body.

A type of blood cell that carries oxygen throughout the body.

A type of blood cell that fights infections and diseases.

Small, cell-like fragments in blood that help with blood clotting.

The liquid component of blood, containing dissolved nutrients, proteins, and waste products.

We breathe to take in oxygen, which is essential for cellular respiration and energy production.

Breathing is mostly involuntary, controlled by the brainstem. You can hold your breath for a while, but your body will eventually take over and force you to breathe.

During inhalation, the diaphragm contracts and flattens, increasing lung volume and drawing air in. During exhalation, the diaphragm relaxes and domes, reducing lung volume and expelling air.

Breathing refers to the mechanical act of taking in and expelling air. Respiration is a chemical process where cells convert glucose into energy in the presence of oxygen.

If capillary walls thicken, gas exchange between blood and tissues will be less efficient, potentially leading to oxygen deprivation and waste accumulation.
