Topic 1 Lesson 1

Biology Basics

• I know what biology is.
• I know the hierarchy of biological organisations.
• I can explain what every level in hierarchy entails.

Learning goals:

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

Keywords:

• organ system
• organism
• population
• ecosystem
• bioma
• biosphere

                                

                                  The study of all living things.

How do we know if something is living?

• By using the 7 characteristics of life MRS GREN.
• Living, non-living & dead

Plant cells vs animal cells

VWO

Basic organelles

Animal and plant cells.

Name	Function
Nucleus	Contains DNA and controls the function of the cell
Cell membrane	Controls what moves in and out of the cell,
Mitochondria	Where respiration takes place (The powerhouse of the cell)
Ribosome	Molecule that synthesises proteins

VWO

Cytoplasm - Solution where the majority of cell activities take place

Basic organelles

Plant cells

VWO

Name	Function
Chloroplast	Where photosynthesis takes place
Vacuole	Space filled with cell sap that keeps cells turgid
Cell wall	Made of cellulose and strengthens cells.
