Organism 
A living thing made up of one or more cells
Cell 
The smallest functional unit of a living organism
Specialised
Cells which serve a unique, particular function
tissue
A cluster of cells which perform a shared function.
Organ
The combination of tissues and cells into a distinct structure that performs a specific function
System
A collection of organs and tissues that perform specific functions necessary for survival
Vascular tissues 
Conducting of tissues that transport water and nutrients throughout the plant. An encompassing term for the xylem tissue and phloem tissue.
Dermal tissue 
Collection of cells that form the outer linings of a plant
Ground tissues
An encompassing term for many different plant tissue types, which are involved in metabolism and support.
Leaves
The plant organs that are responsible for photosynthesis
Flowers 
The reproductive organ of angiosperms. Grows into fruit following fertilisation.
Fruit 
The seed-bearing structures that are responsible for the protection of developing seeds and seed dispersal
Stem 
The main body of the plant that provides support and connects the whole plant
Roots 
The plan organ embedded in the ground. Absorbs water and nutrient from the soil, and provides support to the plant
Root System 
Organ system in plants that is responsible for providing support to the plant and water and nutrient absorption from the soil.
Shoot system 
Organ system in plants made up of reproductive organs, stems, and leaves.
Muscle tissue 
Collection of animal cells that are capable of contraction. Includes skeletal, cardiac, and smooth muscle
Nervous tissue 
Collection of animal cells that sense stimuli and initiate response. Also known as nerve tissue.
Connective tissue 
The collection of many different animal cells that bing and support the other major tissue types.
Epithelial tissue 
One of the basic tissue types of animals that line the outer surface of organs and blood vessels
Digestive system 
The collection of special tissues and organs responsible for the breakdown of food and absorption of nutrients.
Excretory system 
The collection of organs and tissues that remove excess fluid and waste materials from the body.
Endocrine system 
The collection of glands in animals responsible for producing hormones that can be transported into the bloodstream to regulate distant organs/cells
Hormone 
A signaling molecule realeased from endocrine glands that regulates the growth or activity of target cells.
Skeletal system 
The organ system compromised of cartilage and bone that supports the body and the muscular system to enable movement.
Muscular system 
Collection of muscle tissues that circulate blood and enable body movement
Integumentary system 
The organs and tissues responsible for protecting the body from the external environment
Nervous system 
The network of nervous tissue that receives, transmits, and responds to stimuli.
Immune system 
Collection of organs and tissues that provides resistance and protectiong from infection and diseases
Respiratiory system 
The organ system that allows an organism to breathe and exchange gases with the external environment
Blood circulatory system 
The network of blood vessels and the heart that pumps blood around the body.
Reproductive system 
The sex organs responsible for sexual reproduction
