1

Cells

Basic structural and functional units of life that arise only from preexisting cells.

New cards
2

Zygote

The fertilized egg from which all cells in the body can be traced back.

New cards
3

LUCA

Last Universal Common Ancestor, the origin of all cells.

New cards
4

Hadean Eon

The early period of Earth's history characterized by extreme conditions, including volcanic activity and high UV radiation.

New cards
5

Prebiotic Earth

The state of Earth before life, marked by conditions unsuitable for life.

New cards
6

Spontaneous Generation

The theory that living organisms can arise from nonliving material, which has been disproven.

New cards
7

Miller-Urey Experiment

A 1953 experiment that simulated early Earth conditions and demonstrated the formation of organic compounds.

New cards
8

Polymerization

The process of combining small molecules to form larger chain-like molecules called polymers, essential for life.

New cards
9

RNA

A polymer formed from nucleotide monomers, believed to have preceded DNA and capable of self-replication.

New cards
10

Abiogenesis

The process by which life arises naturally from non-living matter.

New cards
11

Pasteur's Experiment

An experiment that disproved spontaneous generation by showing that organisms only grew in broken flasks.

New cards
12

LUCA Evidence

All living cells contain DNA, indicating a common ancestral cell.

New cards
13

Chemoautotroph

An organism that derives energy from chemical reactions, likely characteristics of LUCA.

New cards
14

Eukaryotes

Organisms with complex cells that originated through infolding of plasma membranes and endosymbiosis.

New cards
15

Endosymbiosis

The process by which chloroplasts and mitochondria evolved from independent prokaryotes living within host cells.

New cards
16

Mitochondria

Organelles that produce energy for the cell and are thought to have evolved before chloroplasts.

New cards
17

Multicellularity

The condition of being composed of multiple cells, providing advantages such as longer life spans and increased complexity.
