Plant Biology
Animal and plant organisms, differences
Plant nutrition: autotroph and heterotroph orgamisms.
Plant cell
Plastids: chloroplasts, chromoplasts, amyloplasts
Vacuole: origin, development, functions. Vacuolar content with particular reference to secondary metabolites.
Transport across the plasma membrane. Osmotic phenomena, plasmolysis and deplasmolysis. Osmotic pressure, turgor pressure.

Middle lamella and cell wall. Genesis and development of the cell wall. Cell wall functions.
Chemical components of the cell wall: cellulose, hemicellulose, pectin substances. Secondary modifications of the cell wall: lignification, suberization, mineralization, cutinization.

Tissues in higher plant. Primary and secondary meristematic tissues. Embryonic growth and distension growth. Differentiation. Adult tissues: parenchymatic, tegumental, mechanical, secretory, conductive.

Organography: stem, leaves, root apparatus.
Stem anatomy: vegetative apex, stem primary structure of Dicotyledons and Monocotyledons. Stem secondary structure of Dicotyledons and Gymnosperms. Heteroxylous and homoxylous wood. Functioning of the vascular cambium.

Root anatomy: root apex, root primary structure of Dicotyledons, Monocotyledons and Gymnosperms. Roots secondary structure of Dicotyledons.

Leaves: form, structure and function of the leaves of Dicotyledons, Monocotyledons and Gymnosperms. Gas exchanges between the leaf and the external environment and their regulation mechanisms. Functioning of stomata.
