Front

What organelle breaks down glucose to release energy for the cell?

Back

Mitochondria

Front

What type of cell is present in both plant and animal cells?

Back

Eukaryotic cell

Front

Describe the process of cellular respiration.

Back

Cellular respiration releases energy by breaking down molecules of food in the presence of oxygen.

Front

What organelle serves as the digestive system of the cell?

Back

Lysosome

Front

What type of cell is found in bacteria that lacks a true nucleus and membrane-bound organelles?

Back

Prokaryotic cell

Front

What is the primary function of mitochondria?

Back

To produce ATP through cellular respiration.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a true nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What role do lysosomes play in the cell?

Back

Lysosomes contain enzymes that digest waste materials and cellular debris.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.
