Front

Which organelle stores nutrients, waste, and water?

Back

Vacuole

Answer explanation

The vacuole is the organelle responsible for storing nutrients, waste, and water in a cell. It acts as a storage compartment, making it the correct answer to the question.

Front

Which organelle is the "powerhouse" of the cell?

Back

Mitochondria

Answer explanation

The mitochondria are known as the "powerhouse" of the cell because they generate ATP, the main energy currency of the cell, through cellular respiration. This makes them essential for energy production.

Front

What is the smallest unit of life?

Back

Cell

Answer explanation

The smallest unit of life is the cell. Cells are the basic building blocks of all living organisms, while tissues, organs, and organisms are made up of multiple cells.

Front

What does the cell membrane do?

Back

Controls what enters the cell

Answer explanation

The cell membrane acts as a selective barrier, controlling what enters and exits the cell. This function is crucial for maintaining the cell's internal environment, making 'Controls what enters the cell' the correct answer.

Front

Which organelle controls what enters and exits the cell?

Back

Cell Membrane

Answer explanation

The cell membrane controls what enters and exits the cell by acting as a selective barrier. It regulates the movement of substances, ensuring the cell maintains homeostasis.

Front

What is the purpose of the vacuole?

Back

Store nutrients, water, and waste

Answer explanation

The vacuole's primary purpose is to store nutrients, water, and waste, making it essential for maintaining cellular homeostasis. It does not make energy, control entry and exit, or directly control functions.

Front

Which is not part of cell theory?
- All cells come from other cells
- All organisms are made of cells
- A cell is proportional to the organism
- A cell is the smallest unit of life

Back

A cell is proportional to the organism

Answer explanation

The statement 'A cell is proportional to the organism' is not part of cell theory. Cell theory states that all organisms are made of cells, all cells come from other cells, and a cell is the smallest unit of life.

Front

The chloroplast does what?

Back

The location of photosynthesis

Answer explanation

The chloroplast is the organelle responsible for photosynthesis, where plants convert sunlight into energy. This makes 'The location of photosynthesis' the correct answer, as it directly describes the primary function of chloroplasts.

Front

What is the function of the cell wall?

Back

Gives the cell structure and support

Answer explanation

The cell wall provides structure and support to the cell, helping to maintain its shape and protect it from external stress. This function is essential for the integrity of plant cells and some microorganisms.

Front

What is the purpose of the Mitochondria?

Back

Creates energy for the cell

Answer explanation

The mitochondria are known as the powerhouse of the cell because they create energy in the form of ATP, which is essential for various cellular functions. The other options do not accurately describe the role of mitochondria.
