Scientific Method
The _________ variable is the variable that differs between the experimental and control groups.
Independent Variable
What is cohesion?
water sticks to other water molecules
This organelle surrounds the cell. It controls movement of material both into and out of the cell. What organelle is it?
Cell membrane
This organelle is only found in animal cells and aids in cell division. What organelle is it?
Centrioles
What phase of mitosis are the chromosomes (sister chromatids) lined up in the middle of the cell and ready to begin separation?
Metaphase
______________ refers to the reliability or accuracy of an experiment.
Validity
What is adhesion?
water sticks to other molecules that are not water
This organelle is only in plant cells. It contains a green pigment called chlorophyll and it helps carry out photosynthesis. What organelle is it?
Chloroplasts
This organelle makes proteins and is found in the cytoplasm and attached to the endoplasmic reticulum. What organelle is it?
Ribosomes
What phase of mitosis are the two daughter cells completely formed, but are still stuck together and have not yet separated?
Telophase
A ____________ is a prediction made before an experiment is carried out.
Hypothesis
What is Kinetic Energy?
energy of movement
This organelle controls all the life functions of the cell and has DNA inside of it. What organelle is it?
Nucleus
This organelle stores waste and helps digest food in single-celled organisms. It also breaks down damaged cell parts in multicellular organisms. What organelle is it?
Lysosomes
What phase of mitosis is the cell doing normal cell functions and just starting to replicate its DNA?
Interphase
____________ are aspects of an experiment that are kept constant between the experimental and control groups.
Control Factors
What is Potential Energy?
Energy of Position
This organelle is only in plant cells and is a non-living structure which surrounds and protects the cell. Which organelle is it?
Cell Wall
This organelle is found in the nucleus and makes ribosomes. What organelle is it?
Nucleolus
The two daughter cells completely separate and form two identical cells.
Determining the identity of a flower based on the color and smell is making a ______________.
Inference
What does polar mean?
has a positive and negative pole that create the ability to make bonds
This organelle is the fluid-like material that fills the space between the nucleus and cell membrane. What organelle is it?
Cytoplasm
This organelle is the storage sac of the cell. It is much larger in plant cells than it is in animal cells and it usually stores water, food, and waste. What organelle is it?
