Introduction

Learning Goals:

• I know what biology is.
• I know the hierarchy of biological organisation
• I know the different organ systems and their function
• I know the difference between cells from different organisms

Biology

The study of living organisms. 

Key words:

• biology
• molecule
• organel
• cell
• tissue
• organ
• organ system 

• organism
• population
• ecosystem
• bioma
• biosphere
• integumentary
• nucleus

• mitochondria
• cell wall
• cell membrane
• vacuole
• ribosome
• chloroplast 
• cytoplasm

Organelles: Back to science year 1

Vacuole

nucleus

chloroplast

cell membrane

cell wall

very strong layer that supports the shape of the cell

control center of the cell, which contains DNA

green balls in cells where photosynthesis takes place

bag of water and solutes that cell wants to save

thin layer on the inside of the cell wall which controls what goes in and out of the cell

What components does each cell contain?

facilitates gas exchange between cells and the environment

Breaks down food into usable nutrients

Responsible for transport through the body

Extracts and excretes dissolved waste product from the blood

secretes chemical signals that allow body systems to respond to environmental changes and to one another

allows us to perceive and respond to the world around us

gives the body structure 

 largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain.

responsible for absorbing fat from the digestive system, maintaining fluid balance, and supporting the cells of the immune system

facilitates the production of offspring

Allows the body to move

The hierarchy of biological organization

Organ systems

Body systems and their functions

• Integumentary system - The largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain.
• Muscular system - Allows the body to move
• Reproductive system - facilitates the production of offspring
• Endocrine system - secretes chemical signals that allow body systems to respond to environmental changes and to one another
• Urinary system - Extracts and excretes dissolved waste product from the blood
• Digestive system - Breaks down food into usable nutrients
• Lymphatic system - responsible for absorbing fat from the digestive system, maintaining fluid balance, and supporting the cells of the immune system
• Respiratory system - facilitates gas exchange between cells and the environment
• Nervous system - allows us to perceive and respond to the world around us
• Skeletal system - gives the body structure 
• Circulatory system - Responsible for transport through the body

Cell characteristics of different organisms

Biology has a hierarchical organisation which consists of multiple levels named:  

1.

2.

3. 

etc.

Cells from different organsims have different characteristics:

1. cell wall

2. chloroplast

3. nucleus

4. etc.

The level of organ systems is distinguishes 11 systems which form an organism
