100
The part of the plant that produces seeds.
What is the flower?
100
The part of an experiment is purposely changed by the experimenter (or scientist). There should only be one.
What is the independent variable?
100
The male part of a flower. Consists of the filament and anther. The anther produces pollen grains.
What is the stamen?
100
Four things needed in order for photosynthesis to happen.
What is sunlight, water, carbon dioxide, and chlorophyll?
200
The immature or baby plant inside the seed.
What is the embryo?
200
The part of the plant that anchors it's structure in the ground and soaks up water and minerals from the soil.
What is the roots?

The part of the experiment that stays the same or constant throughout an experiment.
What are the control variables? (Give an example)
200
The female part of the flower that contains the stigma, style, and the ovary.
What is the pistil?
200
Sunlight is trapped in this part of the plant where photosynthesis occurs.
What are the leaves?
300
Also called the seed leaf, this part of the seed is used as a food reserve or food storage.
What is the cotyledon?
300
The part of the plant provides support and has tubes for carrying food, water, and nutrients.
What is the stem?
300
The measurable variable in an experiment that is affected by the independent variable.
What is the dependent variable?
300
This part of the flower attracts insects and mammals to the flower for pollination.
What is the petal?
300
The green cells that live inside the leaves. (Hint: It hosts the party.)
What is chlorophyll?
400
This type of seed has two seed leaves inside the seed coat.
What is a dicot?
400
The part of the plant produces food through a process called photosynthesis.
What are leaves?
400
Written as a statement, it predicts the outcome of an experiment and provides an explanation for an experiment. Often written in "if....then...because" format.
What is a hypothesis?
400
This part of the female part of the flower catches pollen.
What is the stigma?
400
The type of food that plants make in their leaves through the process of photosynthesis.
What is sugar or glucose?

What is the location of the ice cubes?
500
This part of a flower protects the flower and provides support for the petals when in bloom.
What is the sepal?
