Our Team. Agriculture Training. Marketing Tools For Landscapers. Call: By Kaitlyn Ersek on Sep 14, AM Plants can be separated into two distinct categories: monocots and dicots. Monocot vs. Dicot Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. Roots: Fibrous vs. Stems: Arranging the vascular tissue As the monocots develop, the stem arranges the vascular tissue the circulatory system of the plant sporadically.
Leaves: Parallel veins vs. Flowers: How many flower petals does your plant have? What Does This Mean for You? Dicots have two seed leaves inside the seed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant. Homeria Lilium Gloriosa When a monocot seed germinates, it produces a single leaf. It is usually long and narrow, like the adult leaf. Even when it is quite a round shape, there is only one seed leaf in a monocot.
Eryngium Sanguisorba Cladanthus When a dicot germinates, it produces two seedleaves. They contain the food for the new plant, so they are usually fatter than the true leaves. The first true leaves are often a different shape.
They also contain foods to nourish this living part in them. The seed cover basically helps to protect the embryo until it finds a proper location to germinate. The seed leaves or cotyledons provide the necessary energy to develop the embryo until the roots and true leaves are formed.
The embryo in the seed does not germinate until it finds favorable conditions. For this reason, certain seeds have adapted to remain dormant for hundred years or more. Depending on the number of seed leaves, all the seeds can be categorized into two types; monocotyledonous monocot seeds and dicotyledonous dicot seeds.
Seeds are also classified into two categories based on the presence or absence of a special food tissue called endosperm. The most prominent and identifiable feature of many angiosperms is their flowers. Lilies plants in the genus Lilium are good examples—they typically have very prominent flowers with six petals two groups of three , as shown in the following image.
A Lilium canadense flower. Pansies are a popular garden flower and a great example of what dicot flowers look like! Usually, dicots have flower parts in groups or multiples of four or five.
Pansies, like the ones in the following image, have five-petaled flowers. The colors on this particular plant make them easy to see and count: two purple petals, two white petals, and one large yellow petal at the bottom. Pansy flowers. Their shape and the pattern of the veins running through them are great sources of information to help you identify whether the plant is a monocot or a dicot.
Monocots tend to have long leaves with striate venation, meaning that the veins run parallel to each other. Like lilies, onions are easily recognizable monocots. Allium crenulatum, also known as the Olympic onion or scalloped onion. Screenshot of the monocot leaf 3D model in Visible Biology beta. There are two basic layouts for reticulate venation. A dicot leaf can have a pinnate or feather-like pattern, with a central vein running down the middle of the leaf and other veins branching off to either side of it.
Alternatively, it can have a palmate pattern, with veins branching out from a single vein to form a shape resembling the palm of a hand. Fig trees—plants in the genus Ficus —have leaves with a pinnate venation pattern. In the following image, you can see how the leaves of the Ficus elastica and Ficus lutea have a main central vein with other, smaller veins branching off of it at various points along the length of the leaf.
