Classification
This scientist created a classification system using two-part names for organisms.
Who is Carolus Linnaeus?
This cell structure controls the activities of the cell.
What is the nucleus?
This body system breaks down food into nutrients.
What is the digestive system?
Asexual reproduction produces offspring that are genetically this.
What is identical?
Living things in an ecosystem are called this.
What are biotic factors?
The six kingdom system groups organisms based on characteristics like cell type and how they get food.
What is classification?
This structure acts like a “security guard” by controlling what enters and leaves the cell.
What is the cell membrane?
The respiratory and circulatory systems work together to move this gas to body cells.
What is oxygen?
Sexual reproduction increases this in offspring.
What is genetic variation?
Water, sunlight, and temperature are examples of these factors.
What are abiotic factors?
Organisms in this kingdom are single-celled and have no nucleus.
What is Archaebacteria or Eubacteria?
Plant cells have this structure for support, but animal cells do not.
What is the cell wall?
This system removes wastes from the body.
What is the excretory system?
This type of reproduction only needs one parent.
What is asexual reproduction?
A relationship where both organisms benefit is called this.
What is mutualism?
Plants are classified in their own kingdom because they can do this process.
What is photosynthesis?
These organelles release energy from food for the cell to use.
What are mitochondria?
The nervous system sends messages through these.
What are nerves?
Humans breeding dogs for certain traits is an example of this.
What is selective breeding?
A tick feeding on a dog is an example of this relationship.
What is parasitism?
This kingdom includes mushrooms, molds, and yeast
What is Fungi?
This organelle helps break down waste and old cell parts.
What is the lysosome?
This system protects the body from germs and disease.
What is the immune system?
This happens when offspring inherit different combinations of genes from two parents.
What is genetic variation?
All the living and nonliving things interacting in an area make up this.
What is an ecosystem?
