The characteristics of Cells

PART 1 - VOCABULARY

Color the square according to the correct definition.

Cell (red) - Organism (blue) - Membrane (brown) - Prokaryote (Yellow)

Beware- there's a definition that does not have a vocabulary word.

• It's an organism made up of cells that contain their DNA in a nucleus.

• It's a protective layer that covers a cell's surface.

• It's the smallest functional and structural unit of all living things.

• It's any living thing.

What is a cytoplasm?

What is an eukaryote organism? Choose the best definition.

• It's a nucleus, the inner part of a cell.

• It's a single cell organism that does not have a nucleus or membrane bound organelles.

• It's an organism made up of cells that contain their DNA in a nucleus.

• It's yeast.

What is an organelle?

• It's genetic material that provides instructions for all cell processes.

• It's a small body in a cell's cytoplasm that is specialized to perform a specific function.

• It's the region enclosed by the cell membrane.

• It's a single-celled organism.

PART 2 - IMPORTANT PEOPLE

Why do we remember Robert Hooke? CHoose all of the correct answers.

• Because he invented the first light microscope.

• Because he helped developing the cell theory.

• Because he discovered the DNA.

• Because he was the first person to describe cells.

Color the squares according to the person who made that discovery.

Anton van Leeuwenhoek (red) - Matthias Schleiden (yellow) - Theodor Schwann (blue)

Beware - One person did two discoveries.

• He determined all animal tissues are made of cells.

• He described actual living cells.

• He determined that the cell is the basic unit of all living things.

• He concluded that all plants are made of cells.

Explain why cells can't grow too large.

Which of the following statements is true but does NOT belong to the cell theory?

• The cell is the basic unit of organisms.

• All cells carry DNA.

• All organisms are made up of one or more cells.

• All cells come of existing cells.

Which statements are true about DeoxyriboNucleic Acid? There's more than one.

• It's genetic material that provides the instruction for all cell processes.

• Organisms inherit it from their parent or parents,

• It is ALWAYS contained in a nucleus.
