This is a living system with parts that work together to carry out the process or life.
What is an organism?
100
Unicellular organisms are often called by another name, based on their size.
What are micro-organisms?
100
All multicellular organisms begin life as this.
What is a single cell?
100
This organ system replaces photosynthesis in animals
What is the digestive system?
100
These organisms can fail because of damaged genes and environmental factors.
What are cells?
200
These multicellular organisms make their own food using a process called photosynthesis.
What are plants?
200
A chemical reaction involving this element allows organisms to obtain energy from good and release carbon dioxide as a waste product.
What is oxygen?
200
As the number of cells increase, each cell becomes better able to perform this.
What is one particular function within the organism?
200
The organ system uses neurons to transmit signals to the organs in order to sustain the life of the organism.
What is the nervous system?
200
Cancer causes these masses because of dysfunctional cells that divide quickly.
What are tumors?
300
These are the simplest and most abundant unicellular organisms on Earth
What are bacteria?
300
These unicellular organisms are found in aquatic environments. They are covered in cilia that assist in movement towards a food source.
What is a paramecia?
300
This is a group of differentiated cells that work together to perform a specific function
What is tissue?
300
This organ system is made up of the trachea, lung, bronchioles and alveoli.
What is the Respiratory system?
300
This disease is caused by a person's pancreas not producing insulin, which is needed for cells to absorb sugars in the blood/
What is Diabetes?
400
Although these organisms cannot use photosynthesis to create food, they are able to obtain their nutrients by absorbing them from dead and decaying matter
What is a fungi?
400
This organism cab be either unicellular or multicellular. They are usually found in wet or moist environments and have all the organelles typical of an animal cell.
What are Protists?
400
Two or more tissues that work together to perform one or more functions. They fulfill a role in an organ system.
What is an organ.
400
This is a system of tubes in a plant that transports water and minerals from the roots to the shoots and leaves.
What are xylem vessels?
400
These types of organisms are decomposers and can break down dead plant and animal material, releasing the usable nutrients and carbon dioxide into the environment.
What are fungi and bacteria?
500
Organisms can be divided into these two groups; one is made up of a single cell, while the other is a composition of two or more cells.
What are unicellular and multicellular organisms?
500
This enables an organism to change its position in the environment.
What is locomotion?
500
This is the process by which a cell becomes specialized to perform a specific function.
What is cell differentiation?
500
This is a system of tubes in a plant that transports nutrients (such as dissolved sugars) from the leaves to the rest of the plant.
What are phloem vessels?
500
40% of the worlds population is at risk to be infected by this disease which is spread by mosquitoes.
