Proteins, carbohydrates, and lipids
Some important organic molecules studied today that are present in cells include carbohydrates (such as glucose and cellulose), lipids (such as fats and phospholipids), proteins (made up of amino acids), and nucleic acids (such as DNA and RNA). These molecules play crucial roles in various cellular processes like energy storage, cell structure, enzyme function, and genetic information transfer.
Cells are the smallest structures of an organism. (nothing simpler than a cell is considered to be alive)
Atoms do not spontaneously assemble into complex organic molecules or living cells on Earth today due to the highly specific and controlled conditions required for such processes. Biological molecules and cells rely on intricate biochemical pathways and catalytic actions, typically facilitated by enzymes, which are not present in a random environment. Furthermore, the formation of life involves a series of highly improbable steps that require specific environmental conditions, energy sources, and time, which are not readily available or conducive in the current state of Earth's environment.

The main reason organic molecules do not spontaneously form and remain intact today is the presence of more reactive chemicals and environmental factors that lead to their breakdown. Additionally, the conditions on Earth today are not as conducive to the formation and preservation of organic molecules as they were in the early stages of the planet's history.
Today are known the phosphorus molecules P2 and P4.
We studied arthropods at school today.
Not studied up today - but probably not.
Some Protista cells have cell walls, while others do not. Animal cells do not have cell walls, but plant cells do.
