| Embryo | Monocotyledon contains one cotyledon. | Dicotyledons contains two cotyledons. |
Dicot. Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. … Whereas monocots have one cotyledon (vein), dicots have two. This small difference at the very start of the plant’s life cycle leads each plant to develop vast differences.
To distinguish between monocots and dicots, we need to compare different structural traits of angiosperms, viz. roots, stems, leaves and flowers. … If it is a single seed leaf, then it is categorised as monocots and if it is a pair of leaves then it is categorised as dicots.
Monocot leaves are narrow, slender, and longer than dicot leaves. Dicot leaves are broad and relatively smaller than monocot leaves. Monocot leaves are isobilateral in symmetry. Dicot leaves are dorsoventral as the upper and lower surfaces of the leaves are distinguished.
Monocots have vascular bundles throughout the stem’s ground tissue while dicots have their vascular bundles arranged in a ring.
The monocot embryo contains one cotyledon while the dicot embryo contains two cotyledons. This is the key difference between monocot and dicot embryo.
| Monocot Stems | Dicot Stems |

| The vascular bundles are present in a scattered manner, without a specific arrangement. | The vascular bundles have a specific shape. They are also arranged in the form of one or two rings. |
Differences between monocots and dicots Monocots have vascular bundles throughout the stem’s ground tissue while dicots have their vascular bundles arranged in a ring.
Monocot and dicot differ in their roots, stem, leaves, flowers and seeds. The main difference between monocot and dicot is that monocot contains a single cotyledon in its embryo whereas dicot contains two cotyledons in its embryo.
Monocot and dicot plants contain stomata in their leaves as well as in their stem. … The main difference between stomata of monocot and dicot plants is that the guard cells of the monocots are dumbbell-shaped whereas the guard cells of dicot plants are bean-shaped.
A monocot has one seed leaf, and a eudicot has two seed leaves.
The structure which is not common between dicot and monocot embryo is Hypocotyl. Endosperm.
| Zygote | Embryo |
|---|---|
| The term zygote is from Greek word ‘zygotos’ which means to ‘join’ | The term embryo is from Latin work ’embryum’ which means ‘that which grows’ |
| Zygote is unicellular | Embryo is multicellular |
| Feature | In monocots |
|---|---|
| Flowers | Parts in threes (trimerous) or multiples of three (e.g. 3, 6 or 9 petals) |
| Pollen: Number of apertures (furrows or pores) | Monocolpate (single aperture or colpus) |
| Embryo: Number of cotyledons (leaves in the seed) | One, endosperm frequently present in seed |
Vascular structures in the stem move water and nutrients upward from the root to the leaves and transport food downward from the leaves to the root. Monocot stems have bundles of vascular tissue scattered throughout, whereas vascular bundles in dicot stems are arranged in a ring.

Monocots are characterized by leaves that have parallel veins. This means that all the veins start at the base of the leaf and move parallel to one another toward the end. Eudicots have leaves with net veins. These leaves have one main vein in the center of the leaf (mid rid or central vein).
Physical characteristics Monocot plants are marked by seeds with a single cotyledon, parallel-veined leaves, scattered vascular bundles in the stem, the absence of a typical cambium, and an adventitious root system.
How do cells in a meristem differ from cells in other types of plant tissue? They continue to divide; Meristem is embryonic tissue, and it retains the ability to divide.
Monocot embryo is a rudimentary stage of monocots that can develop into a new individual. It occurs inside the seed. Monocots contain one embryonic leaf or cotyledon in its embryo. … A large endosperm is present in the monocot seed as well.
The Epiblast is the immature parts of the embryo. It is a flap like structure. Since, it is around the growing part of the cotyledon. It may be named as the second cotyledon because it is similar to the other cotyledon present in dicot plant even though it is an undeveloped part.
Examples of Monocot Seeds: Rice, wheat, maize, bamboo, palm, banana, ginger, onion, garlic, lilies, daffodils, iris, tulips are examples of Monocot seeds. Characteristics of Monocot Seeds: Cotyledon is single with an embryo.
Difference between Gamete and Zygote: Gametes are unfertilized reproductive cells. Zygote is a fertilised egg or a fertilised egg. As a product of meiosis, gametes are always haploid cells. Since zygote is the product of the fusion of the male and female gamete haploid, it is a diploid structure.
The embryo is the developing organism from fertilization to the end of the eighth week of development. … The foetus is the developing organism from the beginning of the third month to birth.
The zygote contains all of the genetic information (DNA) needed to become a baby. … The zygote spends the next few days traveling down the fallopian tube. During this time, it divides to form a ball of cells called a blastocyst. A blastocyst is made up of an inner group of cells with an outer shell.
