Analysis Questions​

​

AQ1. What would happen to a seed that did not get enough water to soften the food source?  Why?

Be sure to check that you have answered this question completely, including explaining why

Multiple Choice

AQ1.What would happen to a seed that did not get enough water to soften the food source?

• It would not be able to germinate

• It would germinate faster.

• Nothing would happen to it.

• It would quickly rot.

AQ2. ​Were the other seeds you looked at (2 of your choice and the acorn) monocots or dicots? How do you know?

​dicots:

milkweed

​pepper

​white beardtongue

​blazing star

​all beans

​apple seeds

​sunflower

​acorn

​*2 parts to seed

AQ3. Explain what would happen to the germinating plant if an insect munched on the shoot part of the embryo. Why would this happen?

Be sure to check that you have answered this question completely, including explaining why

Multiple Choice

What would happen to the germinating plant if an insect munched on the shoot part of the embryo.

• Nothing would happen. The plant would be fine.

• The new plant will grow faster to try to repair itself.

• The new plant would most likely die because it would not be able to make enough food for itself (once it's above grounf)

AQ4. Choose one seed you looked at. How might that type of seed be dispersed? Explain.

Be sure to check that you have answered this question completely, including explaining

​

​*Milkweed, unidentified seed--wind

​*apple, acorn, sunflower, pepper, beans--animals(often), or drops to ground & tumbles

​*white beardtongue, blazing star--falls to ground & tumbles

Multiple Choice

An acorn is dispersed from the parent tree by:

• floating in the wind

• floating on water

• an animal

• explosion from seed pod

Multiple Choice

An milkweed seed is dispersed from the parent plant by:

• floating in the wind

• floating on water

• an animal

• explosion from seed pod

AQ5.What does it mean to say that a seed germinated? Explain.

Be sure to check that you have answered this question completely, including explaining

Multiple Choice

If a seed germinated it means that the seed

• died

• left the parent plant

• was eaten

• sprouted

AQ6a.Sometimes insects drill holes and lay eggs inside seeds. Why would the insect lay eggs inside the seed?

Be sure to check that you have answered this question completely, including explaining

Multiple Choice

Why would an insect lay eggs inside a seed?

• Insects do not do that.

• The seed provides food and shelter for the larva (baby insects)

• The insect has nowhere else to lay the eggs.

AQ6b.Sometimes insects drill holes and lay eggs inside seeds. What would happen to the seed? Would it be able to germinate?

Be sure to check that you have answered this question completely, including explaining

Multiple Choice

Sometimes insects drill holes and lay eggs inside seeds. What would happen to the seed if the insect egg hatches successfully?

• Nothing will happen to the seed. They just share the space.

• The seed will be more likely to germinate.

• The seed will be stronger and hardier.

• The seed will probably nor germinate as the larva will eat it

CONCLUSION:Write a paragraph that answers the following questions. What did you learn from this lab? How did this lab help you understand seeds and the process of germination? Explain and give specific examples from the lab.

Be sure to check that you have answered these question completely, including explaining and giving specific examples from the lab.

Please go back and chekc your lab to make sure that it is complete and that you have corrected any errors &/or omissions(things you left out).
