Unit 1 Formative 2

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is the site for many cellular processes. It is found in both prokaryotic and eukaryotic cells.

Front

What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a membrane-bound nucleus and organelles. Examples include bacteria and archaea.

Front

What is a eukaryote?

Back

A eukaryote is an organism whose cells contain a nucleus and membrane-bound organelles. Examples include plants, animals, and fungi.

Front

What is a positive feedback loop?

Back

A positive feedback loop is a process that amplifies or increases the effects of a stimulus, leading to a greater response.

Front

What is a negative feedback loop?

Back

A negative feedback loop is a process that counteracts a change, returning the system to its set point or equilibrium.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the function of the nucleus?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What is the rough endoplasmic reticulum?

Back

The rough endoplasmic reticulum (RER) is a type of endoplasmic reticulum that is studded with ribosomes and is involved in protein synthesis and processing.

Front

What is the smooth endoplasmic reticulum?

Back

The smooth endoplasmic reticulum (SER) is a type of endoplasmic reticulum that lacks ribosomes and is involved in lipid synthesis and detoxification.

Front

What are ribosomes?

Back

Ribosomes are small structures within cells that are responsible for protein synthesis.
