Cell Structure and Function

Front

What is the function of the nucleus in a cell?

Back

The nucleus is the structure located in both plant and animal cells that houses DNA, directs cell activity, and is involved in the production of new cells.

Front

What organelles are responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, and they are green due to the chlorophyll pigment found in them.

Front

What is the main function of the smooth endoplasmic reticulum?

Back

The smooth endoplasmic reticulum does not have ribosomes on its membrane and is responsible for the synthesis of lipids for the cell.

Front

What is the role of the cell wall in plant cells?

Back

The cell wall is a rigid structure that surrounds the cell membrane, providing support and protection to the cell.

Front

What does it mean for a cell membrane to be semi-permeable?

Back

A semi-permeable cell membrane allows certain sizes, shapes, and kinds of particles to pass through while blocking others.

Front

What is the primary function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the function 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 role of the Golgi apparatus in a cell?

Back

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

Front

What is the function of lysosomes?

Back

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