Why could cells not be discovered until the microscope was discovered?
Cells are microscopic.
100
Who discovered cells?
Robert Hooke
100
all organisms are composed of ___________
cells
100
* made of cellulose *is rigid, strong, and stiff *provides support and protection for cell * found in plant cells
cell wall
100
*can be attached to the ER or floating free in the cytoplasm
*produces proteins
* found in both plant and animal cells
Ribosomes
100
What is the cell membrane?
The gate keeper of the cell. It controls what enters and exits the cell. It is the most important organelle in maintaining homeostasis.
100
What organelle is this describing?
Cell Membrane
100
_______________ is maintaining internal stable conditions.
homeostasis
100
Empirical evidence is the term used to describe
A. Information gained by direct observation of an event.
B. Cause and effect relationships.
C. Events that are known by their one-time occurrence.
D. All of the above
A. Information gained by direct observation of an event.

What are all living things made up of?
cells
200
Who discovered microscopic organisms such as bacteria?
Anton von Leeuwenhoek
200
True or False: Rudolph Virchow said all animals have cells.
False: Rudolph Virchow stated that cells come from other cells.
200
* provides cell with protection
*control of movement of materials in/out of cell
*support
* found in plant and animal cells
Cell membrane
200
*breaks down food to release energy
*stores energy
*found in both plant and animal cells
Mitochondria
200
Through what do materials go in and out of an organism's cells?
The Cell Membrane
200
The prefix "homeo" means
constant
200
In setting up a scientific experiment, the __________ is the object or situation that is artificially changed and the __________ is the object or situation that is not changed but left under normal conditions.
In setting up a scientific experiment, the _____independent variable_____ is the object or situation that is artificially changed and the ____control______ is the object or situation that is not changed but left under normal conditions.
300
The cell is the ******* unit of a living thing.
smallest
300
Who used a microscope to study animal cells?
Theodore Schwann
300
single-celled organisms that lack a nucleus; prokaryotes
bacteria
300
*controls cell activities
*found in plant and animal cells
Nucleus
300
*digests worn out cell parts *digests dead parts or the entire cell
lysosomes
300
What organelle is found in an animal cell but not plant cells.
Lysosomes
300
What organelle is this describing AND explain why.
Mitochondria because it converts glucose to ATP energy for the cell to live and function. ATP energy is the power cells use to run (maintain homeostasis).
300
What do all organisms need to get rid of in order to live?
Waste
300
When considering the differences between science and nonscience, it is important to remember that topics covered by nonscience
A. Are highly predictable but not provable.
B. Are speculative rather than verifiable.
C. Do not challenge previous assumptions.
B. Are speculative rather than verifiable.
400
If an organism is *******, all functions of life happen within that one cell.
unicellular
400
Who used a microscope to study plant cells?
Matthias Schleiden
400
What did Hooke use when naming a cell? AND what did he view?
A microscope and cork under the microscope to name the cell
400
* clear, thick jelly-like material
* supports and protects cell organelles
* found in both plant and animal cells
Cytoplasm
400
*stores food, Water, and waste
*in plant cells: very few, but very large
*in animal cells: many little ones
vacuoles
400
What is the cytoplasm?
Gel - like structure that holds the organelles in place inside the cell.
400
What organelle takes in the sun's rays , CO2, and water to make glucose? This process is _____.
Chloroplast , photosynthesis
400
What is the function of the chloroplast?
Captures energy from the sun to make glucose (food) for the plant.
400
Which statement(s) is/are generally considered to be true by the scientific community?
A) Eventually science will be able to provide answers for all the problems facing humanity.
B) Science is limited by the ability of people to interpret information.
C) The scientific method can be applied to all types of situations.
D) All of the above.
C) The scientific method can be applied to all types of situations.
