DE Cell Theory, types, and structure

Front

What is the modern cell theory?

Back

The modern cell theory states that all living organisms are composed of one or more cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

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

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the role of the rough endoplasmic reticulum (ER)?

Back

The rough ER is involved in the synthesis and processing of proteins that are to be secreted or sent to the cell membrane.

Front

What is a chloroplast and its function?

Back

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

Front

What is the significance of the outer membrane in bacterial cells?

Back

The outer membrane provides a protective barrier and can contain proteins that are involved in nutrient transport and defense against antibiotics.

Front

What is the structure of a prokaryotic cell?

Back

Prokaryotic cells typically have a simple structure, including a cell membrane, cytoplasm, ribosomes, and a single circular chromosome.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the difference between a photosynthetic bacterial cell and a chloroplast?

Back

Photosynthetic bacterial cells are prokaryotic and perform photosynthesis, while chloroplasts are eukaryotic organelles that also perform photosynthesis.

Front

What is hemolytic uremic syndrome?

Back

Hemolytic uremic syndrome is a condition caused by certain strains of E. coli that can lead to kidney failure.
