Increasing in size and mass
What is the definition of Reproduction?
Producing offspring
What is the definition of Excretion?
Excretion is the removal of toxic waste products of metabolism
What is the definition of Nutrition?
Nutrition is either making their own food or by eating other organisms
What is the function of Chloroplasts?
Site of Photosynthesis Contains Chlorophyll (absorbs light)
What is the function of Vacuole?
Stores cell sap
Contains water, sugar and salt

What are organelles? and example
A specialized part of the cell with its own function
Mitochondrion
What are cells? and example
The basic structural unit of an organism
Animal cell and Plant cell
What are Tissue?
a group of cells with similar structures, working together to perform a shared function
(Muscle)
What are organs?
A group of tissues working together to perform specific functions.
(Lung)
What is an Organ System?
A group of organs working together to perform specific functions
(Respiratory system)
What is Chlorophyll?
This pigment absorbs sunlight and it makes plant leaves look green.
Name 4 Organ Systems?

Kidney and Bladder
What is the function of the Respiratory System?
Allows Oxygen to enter blood and Carbon Dioxide to be
excreted
What is the function of the Circulatory system?
Transports substances (Blood with Oxygen) aroud the body.
What is the function of the Digestive System?
Breaks down food and absorbs products into the body
What is the function of the Excretory system?
Forms and stores urine which is then excreted from the body
