PS 1 Review Unicellular and Multicellular Organisms

Front

What is a unicellular organism?

Back

An organism that consists of a single cell, capable of performing all life functions within that one cell. Example: Amoeba.

Front

What is a multicellular organism?

Back

An organism made up of multiple cells, where each cell can have a specific function. Example: Humans.

Front

What is the main difference between unicellular and multicellular organisms?

Back

Unicellular organisms have one cell that performs all functions, while multicellular organisms have specialized cells that perform specific functions.

Front

What is the function of chlorophyll in plant cells?

Back

Chlorophyll is a pigment that allows plants to perform photosynthesis, converting sunlight into energy.

Front

What is a specialized cell?

Back

A cell that has a specific structure and function, adapted to perform a particular task in an organism.

Front

What is the role of muscle cells in the body?

Back

Muscle cells are specialized for movement and contraction, allowing the body to move.

Front

Why can't a muscle cell perform photosynthesis?

Back

It lacks chlorophyll and is specialized for movement, not for photosynthesis.

Front

What are the characteristics of onion cells?

Back

Onion cells are thin, rectangular, and arranged in a grid-like pattern.

Front

What is an example of a multicellular organism?

Back

Humans, as they are made up of many specialized cells.

Front

What is the significance of cell specialization in multicellular organisms?

Back

Cell specialization allows for more complex functions and efficiency in carrying out life processes.
