There are several differences between monocots and dicots, here are three big ones. The main one (that gave rise to the names) is that monocots have seeds that are one piece (like corn), while dicot seeds can be easily split in half (like peas). Other differences include that monocots have flower parts (like petals) in multiple of threes while dicots usually have them in multiples of 4 or 5. In terms of the leaves, monocots exhibit parallel veins while dicots have reticulated (net-like) veins.
Use the prefix mono (one) and di (two) to help you remember the differences between these two flowering plant types.
Flowering Plants are separated into two distinct groups, although there is some gray areas with certain plants.
Monocots produce one leaf from the seed after germinating; dicots produce 2
Monocots produce parallel leaf veins; dicots produce a net-like display of veins.
The differences continue and become more scientific. Try the link below from Wikipedia to begin with if you need more information.
1)Monocts have single cotyledon (seed leaves) | Dicot have two cotyledons.
2) Monocotyledonous plant have parallel venation | Dicot plant have reticulated venation.
3) Monocotyledonous plant have fibrous root | Dicot plant have tap root.
Monocots and Dicots are types of seeds. There are several differences between them.
Monocots: 1) Have only one seed leaf inside. So when a monocot seed germinates, there is only one leaf that shoots up.
2) Leaves are usually long and narrow.
3) Stems are normally unbranched and the roots are short and stringy.
4) Flowers from monocot seeds are in three parts.
5) Seed pods have three parts and are large and fleshy.
Dicots: 1) Have two seed leaves inside. When a dicot seed germinates, two leaves shoots up.
2) Leaves are different shapes and sizes.
3) Stems are tough and branched. The root system is a single root with smaller roots growing from it.
4) Flowers from dicot seeds have parts in fours or fives.
5) Seeds are a variety of shapes, sizes and textures. They normally contain more seeds in a seedpod than monocots.
The flowering plants (Angiosperms) are divided in to two groups.Namely Monocots & dicots.
Monocots: Plants which have only one colyledon in its seed are called monocots.
- Unbranched stem
- fiborous root system
- no secondary life (The diameter of the stem doesn't change)
- Has a parralel vein system in its leaves.(Reticulated)
- Flower petals are in multiples of three
Eg:Coconut, Grass ,Bamboo ,Paddy
Dicots : Plants which have two cotyledons in its seed is called dicots.
- Branched stem
- tap root system
- Has a secodary life
- Has a webbed vein system
- Flower petals are in multiples of 4s or 5s
Eg: Jak, Beans, Breadfruit, chllies
The difference between Dicotyledons and Monocotyledons are summoned below:-
1 They have tap root system.
2 The leaves have reticulate venation.
3 The leaves are dorsiventral.
4 Seed has two cotyledons.
5 The flowers are usually tetra or pentamarous.
6 The transverse section of root contain 2 to 6 bundles of xylem or pheolem.
7 In stem, vascular bundles are arranged in a ring.
8 There is secondary growth.
1 They have adventitious root system.
2 The leaves have parallel veniation.
3 The leaves are isobilateral.
4 Seed has only one cotyledon.
5 The flowers are usually trimarous.
6 The transverse section of root contains 8-20 bundles of xylem and pheolem.
7 Instem, vascular bundles are scattered.
8 There is no secondary growth.
Monocots, like corn for example, contain one cotyledon and most have extra enegry in the form of endosperm. They also have a fibrous root system.
Dicots, like beans for example, have two cotyledons which are the two halves of the bean seed. The dicot also has the taproot system.
The seeds leaves, also called cotleydons, are different in monocots and dicots. Monocots have 1 cotleydons, while dicots have 2 cotleydons.
- Embryo with single cotyledon
- Pollen with single furrow or pore
- Flower parts in multiples of three
- Major leaf veins are parallel
- Embryo with two cotyledon
- Pollen with three furrows or pores
- Flower parts in multiples of four of five
- Major leaf veins are reticulated
Monocots have one cotyledon
Dicot hyave 2 cotyledon
- They divide in two halves
- There are two cotyledons
- The cotyledons are thick & fleshy
- The Endosperm is usually absent
- The Embryo is large
- Coleoptile & Coleorhiza are absent
- They don't divide in two halves
- There is only one cotyledon
- The cotyledons are thin & narrow
- The Endosperm is Present
- They embryo is small
- Coleoptile & Coleorhiza are present
Monocots and Dicots present quite a few different characteristics. Priminary and most importantly of monocots are consistment of seeds being single piece. While continueing, flowers have petals in multiple of three. In dicots having a case of multiples of four and five. Monocots also permit parallel veins while dicots perform reticulated veins. Steam vascular bundlers being scattered in monocots though are considered ring in dicots.
Numbering of palm, onion, lilly, and onions are in monocot format as for the dicot section, oak, mustard, blueberry, cacti, and even sunflowers. Matter of fact, a surfiet amount in dicots is numbered to 170,000 containing increasement and are also more assorted and comprised due to these numbers. While 65,000 containing decreasement in monocots. Being herbaceous plants consist long, narrow leaves alongside parallel veins in defining Monotyledonae meaning another word for moncot. In docotyledonae as in defining docot either being herbaceous being tomato, woody, or even hickory tree like.
The primary and most important difference is that monocots consist of seeds that are a single piece-an example of which is corn, while dicot seeds can be split into two, like in the case of peas.
Another important difference is that while in monocots the flowers have petals in multiples of three, in the case of dicot these are in multiples of 4 or 5. As far as the leaves are concerned, monocots exhibit parallel veins while dicots have reticulated veins. There are many other features that distinguish the two. Take the case of the embryo for instance. As the name would suggest, and as one would imagine, an embryo in a monocot has a single cotyledon while the embruo with the dicot comes with two cotyledons. Then again in the case of monocots the pollen is with a single furrow or pore, whereas in the case of a dicot it is with three furrows or pores.
In the case of monocots the stem vascular bundles are scattered whereas in the case of dicots these are in a ring. The roots happen to be what is referred to as adventitious in the case of monocots, while the roots develop from radical when it comes to the dicots. Yet another trait that distinguishes the monocot from the dicot is the fact that in the case of the former, secondary growth is totally absent whereas in the case of dicots, it is sometimes present.
A monocot has only one seed leaf (monocot is short for 'monocotyledon'. A cotyledon is a seed leaf, and 'mono' means one). This seed leaf is usually the same shape as the adult leaf, long and thin, and the leaf veins nearly always run parallel to the central midrib. Sometimes, the adult leaves are pinnate, as in many palms, but the veins are parallel on each leaflet. There are several monocot plant families that are instantly recognisable. Many food plants are grasses. So crops like wheat, oats, barley and sweetcorn are all monocots. Palms, Orchids, and most bulbous plants are monocots.
A dicot has two cotyledons (dicot is short for 'dicotyledon', and 'di' means two). The seed leaves are usually rounded and fat, because they are the two halves of the seed. The first true leaves can be many different shapes, from long and thin to rounded or palmate. Most trees and shrubs and many garden annuals and perennials are dicots, and there are many more species of dicots than there are monocots.
