Cell Organelles and Their Functions

In a bustling city, there is a high-tech security gate that controls who can enter and exit a restricted area. This gate is essential for maintaining order and safety in the city. Which external cell structure does this gate represent, as it is present in all cell types and is crucial for maintaining homeostasis by controlling what enters and exits the cell?

• Cell Wall

• Cell Membrane

• Cytoplasm

• Nucleus

In a small town, there is a unique building that stands out due to its strong outer structure. This building is made of sturdy materials that provide shape and additional protection. Most of the buildings in the town are similar to this one, but some, like the local library, have a different structure that lacks this protective feature. However, the houses in the neighborhood do not have this outer structure at all. What is the name of this external structure that provides shape and protection?

• Cell Membrane

• Cytoskeleton

• Cell Wall

• Capsule

Which structures are found in eukaryotic cells, specifically animal cells but not plant cells, originate from the centrosome, and are directly involved in cell division?

• Chloroplasts

• Mitochondria

• Centrioles

• Ribosomes

In a vibrant garden, Samuel is curious about the different parts of the plants. He learns that there is a special organelle found in plant cells but not in animal cells, which is responsible for making sugar and is the primary site of photosynthesis. What is this organelle?

• Mitochondrion

• Chloroplast

• Vacuole

• Nucleus

In eukaryotic cells, what term refers to everything inside the cell except the nucleus, including the jelly-like cytosol and the cytoskeleton, which together support the organelles?

• Cytosol

• Cytoplasm

• Protoplasm

• Nucleoplasm

Nora is a skilled chef in a bustling restaurant kitchen. She relies on a specific eukaryotic organelle, characterized by its many folds, to help transport ingredients throughout the kitchen and process various dishes. This organelle exists in both rough and smooth forms. What is this organelle?

• Golgi Apparatus

• Mitochondrion

• Endoplasmic Reticulum

• Lysosome

What is the primary difference between the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER)?

• RER makes lipids, while SER makes proteins.

• RER is involved in detoxification, while SER processes proteins.

• RER has ribosomes and makes proteins, while SER makes lipids and is involved in detoxification.

• RER is found in plant cells, while SER is found in animal cells.

In a bustling city, there is a factory where various products are assembled. Once the products are put together, they are sent to a special department that receives these assembled items from the production line, then modifies, sorts, and packages these materials for delivery to stores and customers. Which department is responsible for this important task?

• Lysosome

• Vacuole

• Golgi Apparatus

• Peroxisome

Which organelle is responsible for modifying, sorting, and packaging materials for delivery within the cell?

• Lysosome

• Mitochondrion

• Golgi Apparatus

• Ribosome

What organelle, found in some eukaryotic cells, contains enzymes that break down substances?

• Nucleus

• Vacuole

• Lysosome

• Chloroplast
