Cell Structure & Function Test

Front

Which organelle produces proteins?

Back

Ribosomes are the organelles responsible for protein synthesis in cells.

Front

What organelle packages cellular materials and transports them within or out of the cell?

Back

The Golgi Body (or Golgi Apparatus) is responsible for packaging and transporting cellular materials.

Front

In a scenario where a cell has 78% water and is placed in an environment with 25% water, which direction will the water move?

Back

Water will move outside the cell due to osmosis, as it moves from an area of higher concentration (inside the cell) to lower concentration (outside the cell).

Front

Which organelles are needed for a single-celled amoeba to obtain energy?

Back

The cell membrane and mitochondria are essential for energy acquisition in a single-celled amoeba.

Front

What is NOT a characteristic of eukaryotic cells?

Back

Eukaryotic cells do not lack membrane-bound organelles; they are characterized by having them.

Front

What is the function of the nucleus in a cell?

Back

The nucleus houses the cell's DNA and is responsible for regulating gene expression and cell division.

Front

What is the role of mitochondria in a cell?

Back

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

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Front

What is the function of chloroplasts?

Back

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