Characteristics of Living Things
This type of organism gets its nutrients by eating other organisms.
What is a consumer?
The control centre of the cell that contains DNA.
What is the nucleus?
True or false: every multicellular organism needs a mate to reproduce.
What is false?
True or false: A virus can reproduce completely on its own outside a host.
What is false?
A __ is the basic unit of life.
What is a cell?
An organism made of many cells is called this.
What is multicellular?
The jelly-like fluid that fills the cell.
What is the cytoplasm?
This type of cell has a nucleus and membrane bound organelles.
What is a eukaryotic cell?
This is the first step of the virus life cycle.
What is attachment?
This old theory claimed that living things could come directly from non-living matter.
What is spontaneous generation?
This is the process plants use to make energy.
What is photosynthesis?
This organelle captures sunlight and uses it to make food through photosynthesis.
What is the chloroplast?
Bacteria and archaea belong to this type of cell.
What are prokaryotic cells?
The protein head of a virus is called this.
What is a capsid?
This theory states that living things come from other living things.
What is biogenesis?
This process is the opposite of photosynthesis. It produces water, carbon dioxide, and energy.
What is cellular respiration?
This structure acts like the factory's security guard, deciding what enters and leaves the cell.
What is the cell membrane?
These are the two main types of eukaryotic cells. Which one has a cell wall?
What are plant and animal cells? Plant cells have a cell wall?
The newly produced viral parts come together to create complete viruses during this step.
What is assembly?
This scientist looked at a thin slice of cork under a microscope and gave tiny compartments the name we still use today.
What is Robert Hooke?
A fire grows, uses oxygen, releases heat and waste, and can even spread. Why isn't a fire considered a living thing?
What is it's not made of cells?
This organelle produces usable energy for the cell.
A scientist looks at an unknown cell and sees DNA floating freely in the cytoplasm rather than inside a nucleus. What type of cell is it?
What is a prokaryotic cell?
Put these five steps in the correct order: release, replication, attachment, assembly, entry.
What is:
Attachment → Entry → Replication → Assembly → Release
A cancer cell divides repeatedly when it should stop. Which part of cell theory helps explain why this is still not an example of “new life appearing from nothing”?
What is all new cells come from pre-existing cells?
