CELL THEORY & CELL TYPES
Name all 3 principles of the cell theory
1. All living things are made of one or more cells.
2. Cells are the basic unit of structure and function in living things.
3. All cells come from pre-existing cells.
What is the correct order of organization from smallest to largest?
Cell → Tissue → Organ → Organ System → Organism
What organelle is the BEST clue that a cell is a plant cell?
Chloroplasts
What does DNA stand for?
Deoxyribonucleic acid
What traits are passed from parents to offspring?
Inherited traits
What type of cells do not have a nucleus but can still reproduce and perform life functions?
Prokaryotic cells
What level of organization is made of similar cells working together?
Tissue
What structure provides support and is found only in plant cells?
Cell wall
What are segments of DNA that code for proteins and traits?
Genes
What controls eye color?
Genes
Why is the statement “mitochondria are required for reproduction” incorrect?
Because reproduction occurs through cell division
The heart is an example of which level of organization?
Organ
What organelle releases energy in both plant and animal cells?
Mitochondrion
Where are genes found inside the nucleus?
On chromosomes
Why is learning to ride a bike NOT inherited?
It is a learned behavior
What ability do both prokaryotic and eukaryotic cells share?
Carrying out life processes
Which level cannot be skipped without making the order incorrect?
Tissue or Organ
What structure is much larger in plant cells than in animal cells?
Central vacuole
Why is it incorrect to say genes contain DNA?
Because DNA makes up genes
How would freckles be classified?
An inherited trait
What structure separates eukaryotic cells from prokaryotic cells on a diagram?
The nucleus
What level represents a complete living individual?
Organism
A cell has chloroplasts and a cell wall. What type of cell is it?
Plant Cell
What is the best explanation connecting DNA, genes, and chromosomes?
Genes are segments of DNA found on chromosomes that determine traits
What determines whether a trait can be passed to the next generation?
Genetics (or genes)
