(29 cards)
What are the basic units of life?
Cells are the basic unit of life.
What are unicellular organisms?
Unicellular organisms consist of 1 cell.
Example: Bacteria
What is the relationship between structure and function in cells?
Structure = Part, Function = Job.
What are organelles?
Small structures inside the cell that perform a specific function to keep the cell alive.
What structures are present in an animal cell?
Animal cell structures include: Nucleus, cell membrane, mitochondria, ribosomes, lysosome.
What is the input for mitochondria?
Input: glucose, O2.
What are the structures present in a plant cell?
Structures present in plant cells include: chloroplast, cell wall.
What is cellular respiration?
Cellular respiration outputs: CO2, H2O, Energy.
What is the primary function of mitochondria?
To perform cellular respiration and produce energy ( ATP )

What type of cells contain chloroplasts?
Plant cells.
True or False: Ribosomes can be found freely floating in the cytoplasm.
True.
Short Answer: What is the function of the cell wall?
To provide structural support and protection.
What are the levels of organization in humans?
Cells, Tissues, Organs, Organ Systems, Organism
What is an organ system?
An organ system is a collection of organs with a common function.
What is a tissue?
A tissue is a group of cells with a similar structure and function.
What is a cell?
A cell is the basic unit of life. It is made up of many organelles.
What is an organ?
An organ is a group of tissues that have a specific function.
What evidence shows that organs in humans work together?
The interactions of organs like the stomach, small intestine, and liver provide evidence that organs in humans work together, resulting in the survival of the individual.
What is a multicellular organism?
An organism made up of many cells.
Hierarchy: organelles → cell → tissue → organs → organ system → organism
What is a cell?
The basic unit of life.
