EXERCISE 16: PALEODICOTS

• Paleodicots- are flowering plants that are considered to be primitive due to them being presumed to be the first angiosperms.
• Three orders of Paleodicots- Magnoliales, Piperales, Laurales
• Four families of Paleodicots- Annonaceae, Magnoliaceae, Piperaceae, Lauraceae
• Carpels- a tissue of the parent sporophyte where the ovules are enclosed. A structure that differs angiosperms from other seed plants.
• Stigma- a specialized portion of the carpel where the microspores or pollen grains germinate. This is also one of the contributing factors as to how pollination in angiosperms is indirect.
• Angion and sperma- Greek words which means vessel and seed respectively.
• Fruit- an important unit of dispersal of the angiosperms.
• Species representative of the family Annonaceae- Annona muricata
• Species representative of the family Magnoliaceae- Magnolia grandiflora
• Species representative of the family Piperaceae- Piper nigrum
• Species representative of the family Lauraceae- Persea americana
