Biology: Characteristics of Living Things

Living things are made up of cells, which are the basic structural and functional units of life.
Living things grow and develop, which means they increase in size and complexity over time.
Living things reproduce, which means they produce offspring to ensure the continuation of their species.
Living things respond to stimuli, which means they react to changes in their environment.
Living things maintain homeostasis, which means they regulate their internal environment to maintain a stable condition.
Living things metabolize, which means they convert energy and nutrients into the components that make up their cells.

Cell: The basic structural and functional unit of life.
Tissue: A group of similar cells that perform a specific function.
Organ: A structure made up of two or more types of tissues that work together to perform a specific function.
Organ system: A group of organs that work together to perform a specific function.
Organism: An individual living thing made up of one or more organ systems.

Cell membrane: A thin layer of lipid and protein that surrounds the cell and regulates what enters and leaves.
Cytoplasm: A jelly-like substance inside the cell membrane where metabolic reactions take place.
Nucleus: A membrane-bound structure that contains the cell's genetic material.
Mitochondria: Organelles found in the cytoplasm that generate energy for the cell.
Cell wall: A rigid layer outside the cell membrane that provides support and protection.

Prokaryotic cells: Lack a true nucleus and are typically small and simple in structure.
Eukaryotic cells: Have a true nucleus and are typically larger and more complex in structure.

Living things are composed of cells, which are the fundamental units of life.
Growth and development are characteristics of living things, resulting in increased size and complexity over time.
Reproduction is a vital feature of living things, ensuring the continuation of their species.
Living things respond to stimuli, reacting to changes in their environment.
Homeostasis is maintained by living things, regulating their internal environment to maintain a stable condition.
Metabolism is a characteristic of living things, involving the conversion of energy and nutrients into cellular components.

Living organisms consist of cells, which are the basic structural and functional units of life.
Living organisms carry out chemical reactions involving energy transformation, synthesis, and decomposition of organic compounds (Metabolism).
They maintain a stable internal environment despite external changes (Homeostasis).
Organisms grow, develop, and respond to stimuli.
They reproduce offspring either sexually or asexually.
Organisms undergo changes over time through natural selection (Evolution).
They respond to internal and external stimuli.
Living organisms obtain energy and nutrients from their environment (Nutrition).
