Science Flashcard

Front

What are the polymers for proteins, DNA, fats, and sugars?

Back

Proteins are made of amino acids, DNA is made of nucleotides, fats are made of fatty acids, and sugars are made of monosaccharides.

Front

What is the driving force behind diffusion?

Back

The driving force behind diffusion is the concentration gradient.

Front

How can you identify a prokaryotic cell under a microscope?

Back

A prokaryotic cell can be identified by the absence of a nucleus.

Front

What is true about diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What type of cell encloses its DNA in a nucleus?

Back

Eukaryotic cells enclose their DNA in a nucleus.

Front

Define diffusion.

Back

Diffusion is the process by which particles spread from areas of high concentration to areas of low concentration.

Front

What are the main differences between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What role do concentration gradients play in cellular processes?

Back

Concentration gradients drive processes like diffusion and osmosis, allowing substances to move across cell membranes.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.
