Levels of Organization

What is an organ?

• A group of tissues performing similar functions in a multicellular organism.

• A single type of cell that performs a specific function.

• A collection of organs working together to perform a task.

• A structure that is only found in unicellular organisms.

What is a multicellular organism?

• An organism composed of more than one cell, which are organized into tissues, organs, and systems.

• An organism that consists of a single cell and performs all life functions independently.

• An organism that can only survive in a group of similar organisms.

• An organism that is made up of multiple cells but does not have organized tissues.

What is a prokaryotic cell?

• A type of cell that has a nucleus and membrane-bound organelles, typically found in plants.

• A type of cell that DOES NOT HAVE a nucleus and other membrane-bound organelles, typically found in bacteria.

• A type of cell that is larger than eukaryotic cells and has a complex structure.

• A type of cell that can perform photosynthesis and is found in algae.

What is a unicellular organism?

• An organism composed of one cell, like bacteria.

• An organism that can live in extreme environments, like some archaea.

• An organism that consists of multiple cells, like humans.

• An organism that can photosynthesize, like plants.

Define micro-organism.

• A large organism visible to the naked eye.

• An organism that can only be observed using a microscope.

• A type of plant that grows in water.

• An organism that can survive in extreme conditions.

What is a tissue?

• A group of similar cells that work together to perform a specific function.

• A type of organ that performs a specific task in the body.

• A collection of different types of cells that do not interact with each other.

• A fluid that circulates in the body to transport nutrients.

What is a eukaryotic cell?

• A type of cell that lacks a nucleus and membrane-bound organelles, typically found in bacteria.

• A type of cell that HAS A nucleus and other membrane-bound organelles, found usually in plants, animals, and fungi.

• A type of cell that is only found in unicellular organisms.

• A type of cell that can only survive in extreme environments.

What is a cell?

• A small room in a prison or monastery.

• The basic structural and functional unit of all living organisms.

• A type of bacteria that can survive in extreme conditions.

• A unit of measurement for electrical current.

What is adaptation in biology?

• The process or structure by which cells can be more efficient at a function in an organism.

• A method of reproduction in plants.

• The ability of an organism to change its habitat.

• A type of genetic mutation that occurs over generations.
