Cell Theory and Organelles Quiz

The Golgi apparatus is like a cell's post office. It packages and ships proteins to their destinations.

Lysosomes are like the cell's recycling center. They break down waste and unwanted materials.

Vacuoles are storage compartments within a cell. They hold nutrients, waste, and water.

Chloroplasts are found only in plant cells. They capture sunlight and convert it into energy through photosynthesis.

The cell wall is a rigid outer layer found in plant cells. It provides support and protection.

A scientific theory is an explanation of a natural phenomenon that is supported by extensive evidence. It's not just a guess, but rather a well-tested and widely accepted explanation based on years of research.

All living things are made up of cells, which are the basic units of life. This means that whether it's a single-celled bacterium or a large tree, life is organized and built from these basic building blocks.

Organelles are specialized structures within a cell that perform specific functions, similar to organs in a body. Each organelle has a unique role, contributing to the overall functioning of the cell.

Cytoplasm is a jelly-like substance that fills the cell. It surrounds the organelles and contains nutrients that the cell needs to survive.

The cell membrane acts like a security guard, controlling what enters and exits the cell. It protects the cell from harmful substances while allowing in necessary nutrients.

The nucleus is the control center of the cell, containing DNA, which acts like a recipe book for building everything the cell needs.

The nucleolus is located inside the nucleus and is responsible for making ribosomes. Ribosomes are crucial for building proteins, which are essential for many cell functions.

Mitochondria are often called the 'powerhouses' of the cell because they transform sugar into energy that the cell can use. This energy is essential for all cellular activities.
