Cell 1
What is the basic unit of life?
The cell.
Name the garbage collector in the cell.
Lysosomes.
What is the function of the nucleus in a cell?
It controls the cell's activities and contains the DNA.
Which organelle is known as the powerhouse of the cell?
Mitochondria.
I am small in an animal cell, but large in a plant cell and I store water.
Vacuole.
What are the seven characteristics of living things?
Movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition.
What characteristic of life involves the ability to respond to the environment?
What gas is produced during photosynthesis but used during cellular respiration?
What type of a cell lacks nucleus?
A prokaryotic cell/ Bacteria
How do viruses reproduce?
By invading a host cell and using the cell's machinery to replicate.
What organelle is responsible for cellular respiration in eukaryotic cells?
Mitochondria.
What type of energy is converted into chemical energy during photosynthesis?
What reactants do plants take in to perform photosynthesis?
Answer: Carbon dioxide (CO₂) and Water.
What is the main purpose of photosynthesis?
To convert light energy into chemical energy (glucose) for the plant.
No, because it cannot carry out life processes on its own (like metabolism and reproduction).
Which part of the cell is responsible for packaging and transporting proteins?
What is the green pigment in plants that captures light energy for photosynthesis?
What is the difference between plant and animal cells?
Plant cells have a cell wall and chloroplasts, while animal cells do not.
What are ribosomes responsible for?
Protein synthesis.
What is the protein coat surrounding a virus called?
Capsid.
What are the three parts of the cell theory?
All living things are made of cells; cells are the basic unit of structure and function in organisms; all cells come from pre-existing cells.
What are the 2 main differences between Prokaryotic and Eukaryotic cell?
E- Has nucleus and membrane bound organelles and more complex
What are the two main products of photosynthesis?
Glucose and oxygen.
What is the main purpose of cellular respiration?
To convert sugar into energy (ATP) that cells can use.
Name one major difference between viruses and bacteria.
Viruses cannot reproduce on their own; bacteria can.
