2.1 Organisation

·         What make the plant an organism is that they are individual species that can do reproduction. The function is the ‘Transport’ of water which is in the transpiration. Big functions are associated with system which is reproduction and photosynthesis included need to gather water, light and carbon dioxide.

·         System can be defined as organs, tissue; cell that is working together for one overall purpose is photosynthesis. The diagram is an organ of the leaf. The overall function of the leave is photosynthesis, gas exchange and transpiration.

·         The tissues are cells of the same kind due to the same shape and they do the same function.

Organs
Functions
Phloem
Cells transport ‘sap’
Xylem
Transport water and minerals
Paliscide
Main tissue involve photosynthesis
mesophyll
The space for transpiration and photosynthesis


·         Palisade cell: the chloroplast, cell membrane, cell wall the cytoplasm are called organelles; work together to produce the functioning cell. The organization is based on cell, tissue, organs, system and organism.
