Plant Cell
This rigid outer layer gives plant cells support and protection.
What is the cell wall?
This controls what enters and leaves the cell.
What is the cell membrane?
Prokaryotic cells do not have this membrane-bound control center.
What is a nucleus?
According to cell theory, all living things are made of these.
What are cells?
This green organelle captures sunlight to make food.
What is the chloroplast?
This is the “powerhouse” of the cell that produces energy (ATP).
What is the mitochondria?
This is the region where DNA is located in a prokaryotic cell (no membrane around it).
What is the nucleoid?
Cell theory says cells are the basic unit of this.
What is life?
This large structure stores water, food, and waste and helps keep the plant firm.
What is the vacuole?
This organelle contains DNA and controls the cell’s activities.
What is the nucleus?
Give one example of a prokaryotic organism.
What is bacteria?
Where do new cells come from, according to cell theory?
What is existing cells? (or pre-existing cells, OR cell division)
Name two organelles found in plant cells but not in animal cells.
What are the cell wall and chloroplasts? (vacuole also acceptable if described as large central)
True or False: Animal cells have a cell wall.
What is False?
Name two structures prokaryotic cells can still have.
What are cell membrane, cytoplasm, ribosomes, cell wall, or flagellum? (any two)
Name the three main parts of cell theory.
What is: (1) all living things are made of cells, (2) the cell is the basic unit of life, (3) all cells come from pre-existing cells?
Explain how the chloroplast and mitochondria work together in a plant cell.
What is: chloroplasts make food (glucose) through photosynthesis; mitochondria break down food to release energy (ATP)?
Why can an animal cell change shape more easily than a plant cell?
What is: animal cells lack a rigid cell wall (they only have a flexible cell membrane)?
How is a prokaryotic cell different from a eukaryotic cell in terms of organization?
What is: prokaryotic cells lack membrane-bound organelles (very Simple); eukaryotic cells contain complex membrane-bound organelles and have many functions (Very Complex).
Why was the invention of the microscope important to cell theory?
What is: it allowed scientists to see cells and gather evidence that living things are made of cells?
