photosynthesis
photosynthesis means ______
Using light to make food?
What is the purpose of cellular respiration?
To release energy (ATP) from food?
What gas do plants give off that animals need to breathe?
Oxygen (O₂).
What does ATP stand for?
Adenosine Triphosphate.
What controls the cell’s activities?
Nucleus?
What organelle does photosynthesis take place in?
Chloroplast?
What organelle is known as the "powerhouse of the cell"?
Mitochondria.
What gas do animals breathe out that plants need?
Carbon dioxide (CO₂).
What is ATP’s job in a cell?
It gives the cell energy.
What part of the cell acts like a “gatekeeper,” controlling what goes in and out?
Cell membrane?
What gas do plants take in for photosynthesis?
Carbon dioxide (CO₂)?
What sugar is broken down in cellular respiration?
Glucose.
What do plants make during photosynthesis that animals eat for energy?
Glucose (sugar/food).
When a cell uses ATP, what does it change into?
ADP (Adenosine Diphosphate).
What organelle makes proteins?
Ribosomes?
What is the main pigment that captures light for photosynthesis?
Chlorophyll?
What are the products of aerobic respiration?
Carbon dioxide, water, and ATP.
How do animals help plants reproduce?
By spreading seeds or pollinating.
Which cell part makes most of the ATP during respiration?
Mitochondria.
What organelle breaks down waste and worn-out cell parts?
Lysosomes?
Write the full balanced equation for photosynthesis.
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂?
How is anaerobic respiration different from aerobic respiration?
Anaerobic doesn’t use oxygen and makes less ATP (often produces lactic acid or alcohol).
Why do scientists say plants and animals “depend on each other”?
Because plants give animals oxygen and food, while animals give plants carbon
Why do we call ATP the “energy currency” of the cell?
Because cells spend it to do work, like money is spent to buy things.
What is the jellylike substance that fills the cell and holds organelles?
Cytoplasm?
