Ethan, Lily, and Grace are studying grizzly bears for their science project. They learned that a certain type of cells store energy in fatty tissue and help generate body heat in these bears. What type of cells are they?

• Plant cells

• Eukaryotic cells

• Animal cells

• Prokaryotic cells

Answer explanation

The correct choice is eukaryotic cells. These cells store energy in fatty tissue and generate body heat in grizzly bears.

During a school trip to the zoo, Luna, David, and Anika saw a grizzly bear. David, curious about the bear's biology, asked, 'What is the main function of adipose tissue cells in the body of a grizzly bear?'

• They help the bear produce energy

• They help the bear store water

• They help the bear produce blood cells

• They help the bear generate body heat

Answer explanation

Adipose tissue cells in a grizzly bear's body help generate body heat, making it the correct choice.

Liam, Benjamin, and Michael are studying for their biology exam. They are discussing the structure of muscle cells in the human body. Liam says they have an elongated shape, Benjamin thinks they are spherical, Michael believes they are cuboidal, and their teacher says they are flat. Who is correct?

• Liam (Elongated shape)

• Benjamin (Spherical shape)

• Michael (Cuboidal shape)

• Teacher (Flat shape)

Answer explanation

The correct answer is Liam. Muscle cells have an elongated shape.

Aiden, Abigail, and Hannah are studying different types of cells in their biology class. They come across prokaryotic cells. What is the main characteristic of these cells that they should remember?

• They contain a nucleus

• They are larger in size

• They contain membrane-bound organelles

• They are found in plants only

Answer explanation

Prokaryotic cells do not contain a nucleus.

Michael, Isla, and Anika are studying biology. They come across the term 'cell theory'. Michael thinks it means 'Cells are the basic unit of life'. Isla thinks it means 'Cells are only found in animals'. Anika thinks it means 'Cells do not contain genetic material'. Another friend suggests 'Cells are not present in plants'. Who is correct?

• Michael: Cells are the basic unit of life

• Isla: Cells are only found in animals

• Anika: Cells do not contain genetic material

• Friend: Cells are not present in plants

Answer explanation

The correct answer is Michael: Cells are the basic unit of life. This is because cell theory states that cells are the fundamental building blocks of all living organisms.

During a biology class, Arjun, Rohan, and Zoe were discussing how humans generate body heat. They came up with different theories. Arjun suggested it's the muscle cells, Rohan thought it's the adipose tissue cells, and Zoe believed it's either plant cells or prokaryotic cells. According to their biology textbook, who is correct?

• Muscle cells

• Adipose tissue cells

• Plant cells

• Prokaryotic cells

Answer explanation

According to the biology textbook, Arjun is correct. Muscle cells generate body heat.

Michael, Lily, and Scarlett are studying different types of cells in their biology class. They come across eukaryotic cells. What is the main characteristic of these eukaryotic cells that they discovered?

• They do not contain a nucleus

• They are smaller in size

• They contain membrane-bound organelles

• They are found in animals only

Answer explanation

Eukaryotic cells contain membrane-bound organelles, distinguishing them from other cell types.

Zoe, Grace, and Ava are studying biology and they come across a diagram of a eukaryotic cell. They see a structure labeled as 'mitochondria'. What is the primary function of this 'mitochondria' in the cell?

• Produce energy

• Control cell activity

• Store water

• Generate body heat

Answer explanation

The primary function of the mitochondria in a eukaryotic cell is to produce energy.
