Which row was the best placement for the pansies, hydrangeas, and sunflowers? Explain your answer.
Well I put the pansies in the first row being as it said that they liked shade and less direct sunlight. I put the sunflowers in the third row because it said that they prefer direct sunlight. Finally, I put the hydrangeas in the middle row because the description said that they were okay with that and also, that was the only place to put them.
Describe the process of germination and plant growth you observed in the lab activity for a monocot plant. (Hint: Use data chart A to help with your description.)
The monocots both seemed to have a single root that came out of the side of the seed. Then a stem comes out, connecting the roots and the seed. The seed and the stem start to rise out of the ground and the brown sheds off. Leaves start to sprout from the seed. The leaves soot up, straightening out and the seed, split into two, shrivels up and hangs limply to either side of the plant. The dicot had multiple roots that came out of the bottom of the seed. Then the roots grow longer and some stems grow out of the top. Then the stems start to look like leaves.

Describe the process of germination and plant growth you observed in the lab activity for a dicot plant.
The dicot had multiple roots that came out of the bottom of the seed. Then the roots grow longer and some stems grow out of the top. Then the stems start to look like leaves.

Which of your plants was a dicot? Which was a monocot? How could you tell? (Hint: Refer to the lesson for differences in monocots and dicots.)
The hydrangea was a dicot and the pansies and sunflowers were monocots. I could tell because "momo" means one and "di" means two.

What was the correct water level for germination? Why did this water level work best for all the plants in the garden?
The correct water level was two. This was good because it was enough to get them going, but wasn't enough to drown them.


What water level did you select for plant growth during your first attempt? Describe the observations of your plants at this water level. Based on your data, was the level you picked the best choice for optimum growth?
I Chose 3 and the pansies died but the hydrangeas and sunflowers lived and seemed to thrive. I think that they would've lived better if I hadcset the water level to 2.

What pH level did you select for plant growth? Describe the observations of your plants at this pH level. Based on your data, was the level you picked the best choice for optimum growth?
I chose a high pH level and the plants thrived . I would choose the same pH level as I did this time.

Describe your observations of plant growth in zero gravity. Can you provide possible reasons for the growth patterns? (Hint: Refer to tropisms in the lesson for ideas.)

In zero gravity the plant seemed uncoordinated and went every which way. I think that this is because of the fact that plants rely on gravity to know how to grow.
I think that in a real garden, the auxin hormone would stimulate seed germination and plant growth. Also, if I were to set up my own garden in real life, I think I would basically do the same as in a virtual lab, I would place the plants based on how much sun they need, give them as much water as the need I and be Sure to plant them on earth where there is gravity.
