Venation is how a the leaf veins are organized. Netted venation is when there are larger veins with many smaller veins branches making a type of web pattern.
There are many advantages of having a network of veins in a leaf, Firstly there are a strong network of veins which support the lamina. Vascular bundles (veins) are made os vessels and sieve tubes which is advantageous, becausen it allows substances to pass through the leafy system. The veins help the leaf to move water and food through the xylem and phloem tissues.
The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.
9 cotyledons
veins, a photosynthesising region (green), a waxy cuticle on top and a softer side on the underside of the leaf with stomata present (air holes). The leaf is likely to be flexible with no woody parts.
Parallel veins are a common characteristic of many monocots.
The scientific name of an organism is comprised of the two most specific parts of the organism's taxonomy. First is the name of the organism's genus and then the name of the organism's species. Birch trees are in the Betula genus. There are many species of Birch trees which means the second word in the name is different for different types (species) of birch trees. Some example scientific names of birch trees include: Betula ienta (the cherry birch), Betula pubescens (the European white birch), Betula glandulosa (the American dwarf birch).
