In a plant cell, what is the protection barrier that keeps the cell shape together?

Nucleus
Cell Membrane
Microtubules
Cell Wall
None of the Above

Correct Answer

A. Cell Wall

Explanation

The correct answer is Cell Wall. The cell wall is a rigid layer that surrounds the cell membrane in plant cells. It provides structural support and protection to the cell, helping to maintain its shape and prevent it from bursting or collapsing. The cell wall is made up of cellulose fibers and other components, and it also allows for the exchange of substances between neighboring cells. The nucleus, cell membrane, and microtubules are important components of the cell, but they do not specifically serve as the protection barrier that keeps the cell shape together in plant cells.

The Nucleus does...

Nothing
Directs the making of Protein
Provides energy for the cell
Stores energy for the cell
Gives the cell some color

Correct Answer

A. Directs the making of Protein

Explanation

The nucleus is responsible for directing the making of proteins in a cell. This is because it contains the cell's DNA, which carries the instructions for protein synthesis. The DNA is transcribed into messenger RNA (mRNA) in the nucleus, and then the mRNA is transported to the ribosomes in the cytoplasm, where protein synthesis occurs. Therefore, the nucleus plays a crucial role in protein production within the cell.

Inside the cell are these pathways for things to move through the cell called?

Golgi Bodies
Lysosomes
Cell Membrane
Pathology
Endoplasmic Reticulum

Correct Answer

A. Endoplasmic Reticulum

Explanation

The endoplasmic reticulum is a network of membranes inside the cell that is responsible for the synthesis, folding, and transport of proteins and lipids. It consists of two types: rough endoplasmic reticulum (RER), which is studded with ribosomes and involved in protein synthesis, and smooth endoplasmic reticulum (SER), which lacks ribosomes and is involved in lipid metabolism and detoxification. The endoplasmic reticulum acts as a pathway for molecules to move within the cell, allowing for the efficient transport of proteins and lipids to their proper destinations.

This Maze-Like organelle provides energy for the cell. What is this organelle

Vacuoles
Ribosomes
Mitochondria
Flagella
None of the above

Correct Answer

A. Mitochondria

Explanation

Mitochondria is the correct answer for this question because it is a maze-like organelle that provides energy for the cell. Mitochondria are often referred to as the powerhouse of the cell because they produce adenosine triphosphate (ATP), which is the main source of energy for cellular activities. They have a unique structure with inner and outer membranes, and their own DNA. Vacuoles are responsible for storage, ribosomes are involved in protein synthesis, and flagella are responsible for cell movement. Therefore, none of these options provide energy for the cell like mitochondria do.

What is the sac that stores water, food, and waste inside a plant cell?

Storage Sac
Chloroplasts
Cilia
Vacuum
Vacuoles

Correct Answer

A. Vacuoles

Explanation

Vacuoles are the sacs that store water, food, and waste inside a plant cell. They are membrane-bound organelles that play a crucial role in maintaining the cell's shape and turgidity. Vacuoles also serve as storage compartments for nutrients, ions, and waste products. They help regulate the cell's internal environment, control osmotic pressure, and aid in the breakdown and recycling of cellular waste materials. Therefore, vacuoles are responsible for storing and managing various substances within a plant cell.

The double membrane Chloroplast located in a plant cell does what?

Absourbs photosynthesis
Uses sun energy
Give Color
All of the above
None of the above

Correct Answer

A. All of the above

Explanation

The double membrane chloroplast located in a plant cell performs multiple functions. It absorbs sunlight through the pigment chlorophyll, which is essential for photosynthesis. This process converts sunlight into chemical energy, allowing the plant to produce glucose and oxygen. Additionally, chloroplasts contain pigments other than chlorophyll, giving plants their characteristic green color. Therefore, the correct answer is "All of the above" as the chloroplast is involved in absorbing photosynthesis, using sun energy, and giving color to plants.
