Ch 7 Cell and Plasma Membrane

Front

What is the function of the endoplasmic reticulum in a cell?

Back

The endoplasmic reticulum (ER) is responsible for the synthesis, folding, modification, and transport of proteins and lipids within the cell.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, helping to maintain homeostasis.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells have a nucleus, which contains their genetic material, while prokaryotic cells do not.

Front

What are lysosomes and their function in a cell?

Back

Lysosomes are organelles that contain enzymes to break down waste materials and cellular debris.

Front

How do ribosomes contribute to cellular function?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins.

Front

What is the significance of mitochondria in a cell?

Back

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

Front

What is the structure and function of the nucleus?

Back

The nucleus is a membrane-bound organelle that houses the cell's DNA and controls cellular activities.

Front

What is the role 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 homeostasis in the context of cell biology?

Back

Homeostasis is the process by which cells maintain a stable internal environment despite external changes.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.
