Characteristics of Life
What a living thing must HAVE to survive.
What is a need?
The smallest unit that can perform all the processes necessary for life, they are the building blocks of all life.
What is a cell?
Stores water and other materials in the cell. It is larger in plant cells than in animal cells.
What is a vacuole?
Nerve cells, cardiac cells, digestive cells
What are specialized cells?
The two body systems involved in structure and movement in the eukaryotic organism.
What are the Muscular and Skeletal Systems?
What a living thing must DO to survive.
What is a function?
What all cells MUST have.
What are the cell membrane, cytoplasm, and DNA?
The organelle that contains genetic material (DNA) and instructs the cell how to perform. It is the brains of the cell.
A group of specialized cells.
What is a tissue?
Circulates blood and nutrients throughout the body. The heart is its primary organ.
What is the Circulatory System?
The two things the Characteristics of Life are based on.
What are needs and functions?
One or more cells.
What are all living things made of?
Cell wall and Chloroplasts
What organelles do plant cells have that animal cells do not?
A group of specialized tissues that perform a certain function necessary for life.
What is an organ?
Getting rid of wastes like pee and sweat are this organ system's primary function.
What is the Excretory System?
Water, Energy, Exchange of gases, Elimination of waste.
What are the NEEDS of living things?
Single-celled organisms, like bacteria and archaea, that do not have a nucleus.
What are prokaryotic cells?
Chloroplasts.
What is the organelle that helps plants make their own food?
A group of specialized organs that perform a certain function necessary for life.
What is a body system?
Interprets signals in the brain generated by our five senses. Its primary organ is the brain.
What is the Nervous System?
To grow, reproduce, and respond to the environment.
What are the FUNCTIONS of living things?
A multi-cellular organism made up of specialized cells.
What is a Eukaryote?
Mitochondria and Chloroplasts
What are organelles involved in producing food for animal and plant cells?
The muscular and skeletal systems
What are body systems that are made up of structures and not organs?
This system processes food energy and breaks down unused materials for elimination.
What is the Digestive System?
