Lesson 1 - Cells

What is a multicellular organism?

• An organism made up of a single cell

• An organism made up of multiple cells

• An organism that does not have cells

• An organism that can only be seen with a microscope

Which of the following is a structure found in animal cells?

• Chloroplast

• Cell wall

• Mitochondria

• Central vacuole

What is the primary function of the cell membrane?

• To produce energy for the cell

• To control what enters and leaves the cell

• To store nutrients

• To provide structural support

Which of the following best describes the function of a vacuole in cells?

• It helps in photosynthesis

• It stores water and nutrients

• It produces proteins

• It breaks down waste

How do tissues differ from organ systems?

• Tissues are made of cells, while organ systems are made of groups of tissues

• Tissues perform complex functions, while organ systems perform simple functions

• Tissues are larger than organ systems

• Tissues are found only in plants, while organ systems are found only in animals

Identify the structure that is not found in animal cells.

• Nucleus

• Mitochondria

• Cell wall

• Cytoplasm

Which of the following is a function of plant cells that animal cells do not perform?

• Photosynthesis

• Respiration

• Protein synthesis

• Cell division

Describe the role of mitochondria in animal cells.

• They store genetic information

• They produce energy for the cell

• They control cell division

• They transport proteins

What is the main difference between unicellular and multicellular organisms?

• Unicellular organisms have multiple cells, while multicellular organisms have one cell

• Unicellular organisms are always larger than multicellular organisms

• Unicellular organisms consist of one cell, while multicellular organisms consist of multiple cells

• Unicellular organisms do not have a nucleus, while multicellular organisms do

Which of the following is a characteristic of tissues?

• They are made up of different types of cells

• They perform a specific function

• They are larger than organs

• They are found only in animals
