Which organelles are only found in plant cells?

• cytoplasm and vacuole

• nucleus and cell wall

• cell wall and chloroplast

• mitochondria and cytoplasm

Answer explanation

The cell wall and chloroplast are unique to plant cells. The cell wall provides structure and protection, while chloroplasts are essential for photosynthesis, allowing plants to convert sunlight into energy.

What are two major differences found in plant and animal cells?

• Plant cells have a cell wall and chloroplasts, while animal cells do not.

• Plant cells have a nucleus and vacuoles, while animal cells do not.

• Plant cells have no mitochondria or cytoplasm, while animal cells do.

• They are the same.

Answer explanation

The correct choice highlights that plant cells possess a cell wall and chloroplasts, which are absent in animal cells. This distinction is fundamental to their structure and function, unlike the incorrect options.

All living things are made up of...

• cells

• cell tissues

• organ

• organ systems

Answer explanation

All living things are made up of cells, which are the basic units of life. While tissues, organs, and organ systems are important, they are composed of cells, making 'cells' the fundamental building blocks.

Contains chlorophyll (green pigment) and uses the sun to make food

• cell membrane

• cell wall

• chloroplast

• cytoplasm

Answer explanation

Chloroplasts are the organelles in plant cells that contain chlorophyll, the green pigment. They capture sunlight and use it to convert carbon dioxide and water into glucose through photosynthesis, making them essential for food production.

controls movement of materials in and out of the cell, maintains homeostasis

• cell membrane

• cell wall

• chloroplast

• cytoplasm

Answer explanation

The cell membrane controls the movement of materials in and out of the cell and is essential for maintaining homeostasis, making it the correct answer. The cell wall provides structure, while chloroplasts and cytoplasm have different functions.

"power house" of the cell - converts sugar into energy

• cytoplasm

• mitochondrion

• nucleus

• vacuoles

Answer explanation

The mitochondrion is known as the "powerhouse" of the cell because it converts sugar into energy through cellular respiration, making it essential for energy production in cells.

fluid-filled sacs that store food

• cytoplasm

• mitochondrion

• nucleus

• vacuoles

Answer explanation

Vacuoles are fluid-filled sacs in cells that store nutrients, waste products, and other materials. They play a crucial role in maintaining cell turgor and storing food, making them the correct answer for this question.

the brain of the cell

• cytoplasm

• mitochondrion

• nucleus

• vacuoles

Answer explanation

The nucleus is often referred to as the "brain of the cell" because it contains the cell's genetic material and controls its activities, including growth, metabolism, and reproduction.

Which of these is not found in the animal cell and is found in the plant cell? Pick more than one

• cell membrane

• cell wall

• chloroplast

• cytoplasm

Answer explanation

The cell wall and chloroplast are unique to plant cells. The cell wall provides structure, while chloroplasts are essential for photosynthesis. Animal cells do not have these structures, which is why they are the correct answers.

What is in the diagram?

• vacuoles

• cell membrane

• chloroplast

• nucleus

Answer explanation

#3 in the diagram refers to the nucleus, which is the control center of the cell containing genetic material. The other options, such as vacuoles, cell membrane, and chloroplast, serve different functions.
