Parts of a cell: Quiz BWHS

The jelly-like fluid inside of the cell. It holds the organelles in place.

• cytoplasm

• chloroplasts

• cell membrane

• cytokinesis

Answer explanation

The jelly-like fluid that holds organelles in place is called cytoplasm. It provides a medium for biochemical reactions and supports the cell's structure, making it the correct answer.

Responsible for packaging, modifying, and moving substances from the cell.

• mitochondria

• Golgi apparatus

• smooth ER

• rough ER

Answer explanation

The Golgi apparatus is responsible for packaging, modifying, and transporting substances within the cell, making it the correct choice. Mitochondria produce energy, while ER types are involved in synthesis, not packaging.

Jelly bean shaped structures that break down food molecules and release energy.

• chloroplasts

• lysosomes

• cytoplasm

• mitochondria

Answer explanation

Mitochondria are jelly bean-shaped organelles that break down food molecules through cellular respiration, releasing energy for the cell. Chloroplasts are involved in photosynthesis, lysosomes digest waste, and cytoplasm is the cell's fluid.

The control center of the cell. It houses DNA.

• nucleus

• nucleolus

• mitochondria

• cell membrane

Answer explanation

The nucleus is the control center of the cell, containing the cell's DNA. It regulates gene expression and is essential for cell function, making it the correct answer.

A structure that makes ribosomes. Found in the nucleus.

• smooth ER

• nucleolus

• nucleus

• rough ER

Answer explanation

The nucleolus is a structure within the nucleus responsible for producing ribosomes. It synthesizes ribosomal RNA and assembles it with proteins to form ribosomal subunits, making it the correct answer.

This is an organelle that loops back and forth and detoxifies the cell.

• rough ER

• smooth ER

• lysosomes

• Golgi

Answer explanation

The smooth ER is an organelle that detoxifies the cell and is characterized by its looping structure. Unlike the rough ER, it lacks ribosomes and is primarily involved in lipid synthesis and detoxification processes.

These are liquid filled spaces found in animal cells.

• lysosomes

• vacuoles

• ribosomes

• chloroplasts

Answer explanation

Vacuoles are liquid-filled spaces in animal cells that store substances and help maintain cell pressure. Lysosomes contain enzymes, ribosomes synthesize proteins, and chloroplasts are involved in photosynthesis, which are not found in animal cells.

These are round organelles that digest waste, old cell parts and food.

• ribosomes

• lysosomes

• chloroplasts

• vacuoles

Answer explanation

Lysosomes are round organelles responsible for digesting waste, old cell parts, and food. They contain enzymes that break down these materials, making them essential for cellular maintenance and recycling.

This is a rigid structure that provides support to plant cells.

• cell membrane

• cell wall

• cell gateway

• central vacuole

Answer explanation

The cell wall is a rigid structure that surrounds plant cells, providing support and protection. Unlike the cell membrane, which is flexible, the cell wall maintains the cell's shape and prevents excessive water intake.

These organelles contain green chlorophyll. They make food for plants.

• lysosmes

• chloroplasts

• ribosomes

• vacuoles

Answer explanation

Chloroplasts are the organelles in plant cells that contain green chlorophyll, which is essential for photosynthesis. They convert sunlight into food, making them crucial for plant survival.
