What is an organelle?
- Organelles are tiny structures inside a cell that carry out the functions of the cell.
- Organelles are tiny structures inside a cell that transport nutrients and proteins throughout the cell.
- Organelles are round structures that contain chemicals that breakdown certain unwanted materials in the cell.
- Organelles are structures inside the cell that convert energy in food molecules to energy the cell can use to carry out its functions.
Correct Answer

A. Organelles are tiny structures inside a cell that carry out the functions of the cell.

Explanation

Organelles are tiny structures inside a cell that carry out the functions of the cell. This means that organelles are responsible for performing specific tasks within the cell, such as producing energy, synthesizing proteins, and storing genetic material. They are like specialized compartments within the cell that work together to ensure the proper functioning and survival of the cell.

Why is chromatin important to the cell?
- Chromatin is important to the cell because the thin strands of chromatin contains genetic material (DNA), the instructions for directing the cell's functions.
- Chromatin is important to the cell because the small object floats around the nucleus and produces the ribosomes that make proteins for the cell.
- Chromatin is important to the cell because is a clear, thick gel-like fluid that keeps the other organelles moving throughout the cell.
- Chromatin is important to the cell because it is a ribbon-like structure that helps transport proteins from the nucleus to other areas of the cell.
Correct Answer

A. Chromatin is important to the cell because the thin strands of chromatin contains genetic material (DNA), the instructions for directing the cell's functions.

Explanation

Chromatin is important to the cell because it contains the genetic material (DNA) which carries the instructions for the cell's functions. DNA is responsible for encoding the proteins that are essential for the cell's structure, metabolism, and overall functioning. The thin strands of chromatin help to package and organize the DNA, allowing for efficient storage and retrieval of genetic information. Therefore, chromatin plays a crucial role in maintaining the integrity and functionality of the cell.

Identify which organelle is in one part covered with ribosomes and one part is a network of passageways that carry materials from one part of the cell to another?
- Endoplasmic reticulum
- Golgi Bodies
- Peroxisomes
- Chromatin
Correct Answer

A. Endoplasmic reticulum

Explanation

The endoplasmic reticulum is the correct answer because it is an organelle that has two distinct parts. One part, called the rough endoplasmic reticulum, is covered with ribosomes which are responsible for protein synthesis. The other part, called the smooth endoplasmic reticulum, is a network of passageways that transport materials, such as lipids and proteins, from one part of the cell to another. Therefore, the endoplasmic reticulum fits the description given in the question.

Identify the plant cell organelle that packages proteins and carbohydrates and exports it from the cell.
- Golgi bodies
- Endoplasmic reticulum
- Ribosomes
- Centrosome
Correct Answer

A. Golgi bodies

Explanation

The Golgi bodies, also known as the Golgi apparatus, are responsible for packaging proteins and carbohydrates within the plant cell. These organelles receive proteins and carbohydrates from the endoplasmic reticulum and modify them by adding necessary molecules. The Golgi bodies then package these modified proteins and carbohydrates into vesicles and transport them to the cell membrane for export out of the cell. Therefore, the Golgi bodies play a crucial role in the export of proteins and carbohydrates from the plant cell.

Identify the plant cell organelle that was a dense center and radiating tubes that is used during cell division to help the cell divide its material into two equal parts and move to opposite sides of the dividing cell.
- Centrosomes
- Chromatin
- Mitochondria
- Ribosomes
Correct Answer

A. Centrosomes

Explanation

Centrosomes are the correct answer because they are organelles found in plant cells that contain a dense center and radiating tubes called microtubules. During cell division, centrosomes play a crucial role in organizing the microtubules and spindle fibers, which help in the separation of chromosomes and the movement of genetic material to opposite sides of the dividing cell. This ensures that the cell can divide its material into two equal parts and form two daughter cells.
