Front

Which part of the seed emerges first during germination?

Back

radicle

Front

Which of the following is NOT a controlled variable in the experiment? Concentration of detergent, Number of seeds, Temperature of the environment, Type of detergent, The amount of light

Back

Concentration of detergent

Front

What is the purpose of the control group in the experiment?

Back

To compare the results with a standard where no detergent is used.

Front

How are the dependent variables measured in this experiment?

Back

By counting the number of seeds germinated and measuring root length

Front

Back

It can be broken down by bacteria in water.

Front

What would happen if a farmer irrigated crops with water containing 1% detergent?

Back

The crop yield might be reduced.

Front

What is NOT necessary for seed germination? Options: light, water, oxygen, proper temperature.

Back

light

Front

In the experiment, what was the hypothesis?      a
Options: The seeds will germinate only in full light.  , Detergents with phosphates will make the seeds grow better.  , Different concentrations of detergent will affect seed germination and growth.  , Radish seeds will germinate faster in the control group.  

Back

Different concentrations of detergent will affect seed germination and growth.  

Front

What is the function of the seed coat?  

Back

To protect the seed and help it remain viable
