UNIT 2:Cells: Structure and Function & Body Systems Interactions

Front

What is a cell membrane?

Back

A cell membrane is a protective barrier that surrounds the cell, controlling what enters and exits. It is found in both plant and animal cells.

Front

What type of cell lacks a nucleus?

Back

Prokaryotic cells are cells that do not have a nucleus.

Front

Which organelle is responsible for packaging and transporting proteins?

Back

The Golgi Apparatus is the organelle that modifies, sorts, and packages proteins for secretion or delivery to other organelles.

Front

What organelles are unique to plant cells?

Back

Chloroplasts and cell walls are organelles that are only found in plant cells.

Front

What is the function of chloroplasts?

Back

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

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the control center of the cell, containing DNA and regulating gene expression.

Front

What are the main components of the cell theory?

Back

The cell theory states that: 1) All living things are made of cells, 2) Cells are the basic unit of life, 3) All cells come from pre-existing cells.

Front

What is the function of the ribosome?

Back

Ribosomes are the sites of protein synthesis in the cell.

Front

What body systems interact when you touch something hot?

Back

The Nervous and Muscular systems interact to cause a reflex action when you touch something hot.

Front

What is the function of the mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating energy in the form of ATP through cellular respiration.
