Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that lacks a membrane-bound nucleus and organelles. Its DNA is free-floating in the cytoplasm.

Front

What are nucleotides?

Back

Nucleotides are the basic building blocks of nucleic acids (DNA and RNA) and consist of a sugar, a phosphate group, and a nitrogenous base.

Front

How do genes respond to environmental changes?

Back

Genes are turned on and off in response to environmental factors, allowing organisms to adapt to their surroundings.

Front

Which kingdoms of life contain chloroplasts?

Back

The kingdoms Protista and Plantae contain organisms with chloroplasts, which are involved in photosynthesis.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy (ATP) through cellular respiration.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What role do chloroplasts play in a cell?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on shared characteristics.

Front

What is the significance of free-floating DNA in prokaryotic cells?

Back

Free-floating DNA indicates that the cell is prokaryotic, as it lacks a defined nucleus.
