Botany

• Leaf is an organ of the plant which is responsible for
• Line of the lamina
• Veins is line of the lamina
• leaf base where a leaf attaches to stem
• Petiole is long,thin,stalk and links the blade to stem
• Lamina is the green flat surface
• Margin is line of the leaf
• Reticulate venation web like,random placement of veins
• Parallel venation is veins and parallel to each other
• Simple leaf is one leaf in one petiole
• Compound leaf is two or more in one petiole
• Function of leaf, Photosynthesis
• Transpiration removes excess water from plants into athmosphere
• Guttation removes excess water from xylem
• Storage to store water and nutrients
• Defense for protection for being damage
• Flowers can be source of nectar
• Flower produce seeds
• Complete sepals,sepals,plus sexual parts
• Incomplete lacks either petals or sepals
• Male reproductive parts are anther and fillament
• Fillaments supports anther
• Anther produce and store pollen
• Female reproductive parts are stigma,style,ovary
• Stigma is the topmost part
• Style connects stigma and ovary
• Ovary organ that holds a lot of ovules seed formation takes place
• 2 types of reproduction sexual and asexual
• pollen from the same flower or from another flower on the same plant is called self pollination
• Cross pollination are pollen that transfered to a flower from a different plant
• Develops laterally at the node
