Quote: "The cell is the most basic/smallest unit of life."

Highlight: Early Earth conditions, lacking oxygen and containing various gases, provided the environment for life's origin.

Definition: LUCA (Last Universal Common Ancestor) represents the theoretical first living organism sharing common features with all current life.

Vocabulary: Hydrothermal vents are mineral-rich environments potentially linked to life's origins.

Example: Prokaryotic structures include cell membrane, cell wall, capsule, flagella, pili, ribosomes, and nucleoid.

Highlight: The endomembrane system evolved through membrane infolding, representing a crucial step in cellular evolution.

Definition: Buoyancy is the upward force exerted by a fluid on an object immersed in it.

Highlight: Water's properties include thermal conductivity, viscosity, and buoyancy, all crucial for biological processes.

Example: The Goldilocks Zone represents Earth's perfect position for maintaining liquid water, neither too hot nor too cold.
