bio now - cell size

What were the conclusions of this experiment?

Cells have a high surface area to volume ratio. Large size is beneficial to cells. Small cell size helps sustain all chemical reactions needed for life.

The cell theory states

all organisms are composed of cells. cells are the basic unit of structure and function. cells come from pre-existing cells.

Which of the following are eukaryotic organisms?

animal plant fungi

The basic unit of life is a(n)

cell

As cell size __________, the rate of waste exchange increases.

decrease

The purpose of this experiment was to

determine why cells are small.

An increase in cell size results in an increase in surface area to volume ratio.

false

Which factor was being measured in the experiment?

how long it took the wood to completely burn

To help deal with their larger size (and therefore, small surface area to volume ratio), Eukaryotic cells are compartmentalized into structures known as

organelles

Both combustion and cellular respiration require

oxygen

One common structure found in both prokaryotic and eukaryotic cells is a(n)

ribosome

Which factor was changed between each trial?

size of wood pieces

Why is it beneficial for cells to be small?

to quickly move waste products out of the cell to facilitate faster cellular reproduction

Prokaryotic cells generally have a higher surface area to volume ratio than eukaryotic cells.

true

What was used to ignite the fire evenly?

two egg cartons
