Biology and Horticulture
Biology and Horticulture involve the study of living things. Students will study Genes, Cells, Genetics, Plants and animals, and Evolution. in addition the students studying Horticulture will investigate features of plants, growing plants and environmental sustainability.
The main ideas covered in senior Biology include:
All organisms share a common set of essential life processes
Because of their shared evolutionary history, all organisms share a common set of essential life processes (movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition) and use the same genetic system to maintain continuity.
Organisms interact with each other and with their environment
Living systems are organised and regulate themselves at the cell, organism, and ecosystem levels. Each of these dynamic systems maintains stability in response to a changing environment and their responses impact in turn upon the environment.
Species arise, change, and become extinct over time
Evolution results in diverse adaptations to ensure survival. This diversity allows organisms to occupy different niches within an ecosystem.
Genetics maintain continuity plus allow for change
The inherited sequence of DNA underlies an organism's phenotype such as shape or blood type. Heritable mutations allow evolution or genetic change over time.
