MS Biology UNIT 1 Lesson 1: Cells and organisms

What is the definition of living things?

• Beings that can grow, reproduce, and respond to their environment
• Non-living entities
• Beings that cannot grow or reproduce
• Beings that are invisible

What are cells known as?

• The building blocks of living organisms
• The smallest living organisms
• The smallest unit of energy
• The building blocks of non-living things

What are the two main types of organisms?

• Unicellular and multicellular
• Plants and animals
• Fungi and bacteria
• Multicellular and non-living

What is cell specialization?

• When cells have specific roles to play
• When cells divide into new cells
• When cells are too small to be seen with the naked eye
• When cells cannot interact with their environment

What is cell division?

• A process in which a cell splits into two new cells
• The process of creating unicellular organisms
• The process of creating non-living things
• A process in which cells combine to create new organisms

Why is cell division essential for living organisms?

• For growth, repair, and reproduction
• To create new organisms
• To create non-living things
• To create energy

How do scientists study cells?

• By using a microscope
• By using a telescope
• By using a binocular
• By using their naked eye

What is the cell theory?

• All cells come from other cells
• Cells are not the building blocks of living organisms
• Cells do not carry out essential functions
• Cells are not essential for living organisms

What are the functions of cells?

• Taking up nutrients, getting rid of waste, and interacting with their environment
• Taking up oxygen, producing carbon dioxide, and interacting with other cells
• Taking up water, producing nutrients, and interacting with the sky
• Taking up food, producing energy, and interacting with machines

Why are cells important in the world of biology?

• They are the fundamental building blocks of all living things
• They are the smallest living organisms
• They are not essential for living organisms
• They cannot adapt to their environment
