Parts of Cells
Plant Cells ____ have cell walls
Do, the correct answer is "do" because plants have cell walls made of a strong material called cellulose. These cell walls help protect and support the plant cells. Since animal cells come in so many various shapes, they don't have cell walls.
A scientific theory is different from an everyday theory because ...
Scientific theories are based on years of observation and experimentation. They are backed by the Scientific community and give explanations about the natural world.
The Cell Theory states that all living things are composed of one or more __________.
Cells.
Animal Cells are this type of cell
Eukaryotic
Name the 3 Domains:
Bacteria, Archaea, Eukarya
These green structures inside plant cells capture sunlight and change it into a form of energy cells can use to make food, what part of a plant cell has this job?
The answer is "Chloroplasts." Chloroplasts are green structures inside plant cells capture sunlight and change it into a form of energy cells can use to make food. This process is called photosynthesis. If animal cells contained chloroplasts, you would be as green as grass!
This is the variable that is measured during a scientific experiment.
What is the Dependent Variable
Cells are considered to be the smallest _________ structure.
LIVING
Nucleus
A scientific name is composed of what two levels of classification?
The last two - Genus and species.
These are rod-shaped structures that carry out cellular respiration- the process that releases energy that the cell uses to live and function properly.
Mitochondria
Testing how two different plants foods affects the growth of marigolds is an example of a:
Scientific experiment
In England, a man named Robert Hooke built his own light microscope. One day, he used his microscope to look at a thin slice of cork. He saw rectangular spaces and thought they looked like the little rooms monks live in. So, he coined this term.
What is Cell
These types of cells are always unicellular
Prokaryotic
Fungi
Animal and Plant Cells contain a ____ ________ that surrounds them and keeps their cytoplasm in place.
Animal and Plant Cells contain a Cell Membrane. Cell Membrane's control which substances pass in and out of a cell. Cells need food particles, water, and oxygen, so these enter through the cell membrane. Waste leaves through the cell membrane
This is a quest to gather information through observation in the real world. It can apply to real-life situations, however the conducting scientist may not be able to control the environment or the outcome.
Scientific Investigation
All cells come from __________.
Other Cells, pre-existing cells.
Give an example of a prokaryotic cell
Bacteria; Archaea
The scientific name of a honeybee is Apis mellifera.
Name the honeybee's GENUS.
Apis
In Eukaryotic cells, this is where the DNA is housed and held.
The nucleus
Explain why "I think my dog runs faster than my cat" is NOT a Scientific Theory.
This is a personal observation and hypothesis. It does not involve the entire globe.
Being made of cells, responding to stimuli, ability to grow, develop, reproduce, needing nutrients ... These are examples of:
Characteristics of Living Things
All Eukaryotic cells belong to the _______ Domain.
Eukarya
The Bacteria Kingdom belongs to what Domain?
