What is the main function of the mitochondria in a cell?

Respiration occurs here releasing energy.

Light energy is absorbed & changed into food here.

Proteins are made (synthesised) here.

Support the cell and keeps its shape.

What is the role of the ribosome in a cell?

Proteins are made (synthesised) here.

Controls the movement of substances in & out.

Full of cell sap & maintains shape.

Support the cell and keeps its shape.

What is the function of the vacuole in a cell?

Full of cell sap & maintains shape

Controls the activity of the cell.

Respiration occurs here releasing energy.

These is where many reactions take place.

Which of the following best describes a difference in size between prokaryotic and eukaryotic cells?

Prokaryotic cells are generally smaller than eukaryotic cells.

Prokaryotic cells are generally larger than eukaryotic cells.

Eukaryotic cells are generally smaller than prokaryotic cells.

Both types of cells are the same size.

Explain why the potential difference across each lamp in a parallel circuit is equal to the voltage of the cell.

Because each lamp is directly connected across the cell terminals.

Because the current splits equally between the lamps.

Because the resistance of the lamps is very high.

Because the voltage is divided among the lamps.

Explain why the potential difference across each lamp in a parallel circuit is equal to the potential difference of the cell(s) supplying the circuit.

Because each branch in a parallel circuit receives the full voltage from the cell(s).

Because the current splits equally in parallel circuits.

Because the resistance is higher in parallel circuits.

Because the lamps are identical.

When cells are connected in series, how is the total potential difference supplied to the circuit calculated?

By adding the individual potential differences together

By multiplying the individual potential differences

By subtracting the smallest potential difference from the largest

By dividing the total number of cells by the potential difference of one cell

Why is it important that all cells are connected in the same direction when connected in series?

To ensure the circuit is complete

To reduce the total potential difference

To make the circuit more complex

To decrease the current in the circuit

When identical cells are connected in parallel, what is the total potential difference supplied to the circuit?

The potential difference of just one cell

The sum of the potential differences of all cells

Double the potential difference of one cell
