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. Roots: Fibrous vs. taproot. Once the embryo begins to grow its roots, another structural difference occurs. Monocots tend to have “fibrous roots” that web off in many ...
Dicotyledons have two embryonic leaves on the seed. Some examples are pea, lentils, beans, etc. The root system of both these types of plants has unique, distinguishable characteristics. We will study them in this article. The anatomy of monocot and dicot roots are explained in the article. Monocot Root. A monocot root shows 5 distinct regions.
Dicot Root. These plant roots have a comparatively narrow, and tap root-like structure. Normally, dicots and monocots differ in four aspects which include stems, flowers, leaves, and roots. Here let us know more about the differences between a monocot and dicot roots of a plant. The Dicot and Monocot Roots are distinguished mainly based on the ...
A look at monocot and dicot stems. 1. The stem supports the plant, facilitates water and nutrient transport between the different parts of the plant, and contains tissues that help the plant grow. The stem supports the plant, holding up the plant’s leaves, flowers, and fruits. Within the stem, bundles of vascular tissue, consisting of xylem ...
Monocot plants have a fibrous root system. This type of root system is located near the soil surface, and it forms a dense network of roots that al...
There is no pith region in monocot roots. Even if the pith region is present it would be in a reduced state. It is formed of polygonal parenchymato...
The single-layered,thin-walled, colourless polygonal parenchymatous outer layer of the monocot root is called the piliferous layer. It is also call...
Cortex: It is made up of multi-layered oval parenchymatous cells and has intercellular spaces. These spaces help in gas exchange and storage of starch. In monocots, few layers of cortex below the epiblema give rise to a layer called exodermis which is made from multi-layered cuticularised sclerenchyma cells.
The phloem system consists of sieve tubes, phloem parenchyma and companion cells, Phloem fibres are absent or reduced. Pith: It is centrally located and is very small and is made of polygonal parenchymatous cells. It functions as a storage unit of food.
Most monocotyledons are angiosperms and the seed contains one embryonic leaf. Some examples are ginger, onions, and wheat. Dicotyledons have two embryonic leaves on the seed. Some examples are pea, lentils, beans, etc.
A: There is no pith region in monocot roots. Even if the pith region is present it would be in a reduced state. It is formed of polygonal parenchymatous cells and acts as a food storage unit.
Some plants have both tap roots and fibrous roots. Dicot plants show a tap root system and it grows down vertically. The root system penetrates deep into the soil and many small lateral roots arise from this type of root. 2.
Difference Between Dicot And Monocot Root 1 Monocotyledons or Monocot commonly refers to the flowering plants or angiosperms in which the seeds typically contain only one embryonic leaf or Cotyledon. Ginger, onions, wheat, and grass are the best examples of Monocotyledons 2 Dicotyledons or Dicot is generally referred to the flowering plants or angiosperms in which the seeds typically contain two embryonic leaves or cotyledon. All legumes, including beans, lentils, pea, and peanuts are the best examples of dicotyledons. There are around 1 lakh to 1.5 lakhs of different species of dicot plants.
Ginger, onions, wheat, and grass are the best examples of Monocotyledons.

In monocot stems, the vascular bundles are scattered throughout the ground tissue. Like monocot roots, monocot stems are protected by an outer layer of dermal tissue called the epidermis. The rest of the stem is made up of ground tissue and vascular tissue. The vascular tissue is arranged into bundles of xylem and phloem ...
The xylem transports water and dissolved minerals from the roots to the stem and leaves. The phloem transports dissolved sugars and organic compounds from the leaves to the stem and roots . Cambium (present in dicots but not monocots) gives rise to secondary xylem and phloem.
The stem supports the plant, facilitates water and nutrient transport between the different parts of the plant, and contains tissues that help the plant grow. The stem supports the plant, holding up the plant’s leaves, flowers, and fruits.
The rest of the stem is made up of ground tissue and vascular tissue. The vascular tissue is arranged into bundles of xylem and phloem that are scattered throughout the ground tissue. Within each bundle, the phloem is located closer to the outside of the stem, and the xylem is located closer to the inside of the stem. 3.
The stem provides new living tissue for the plant via primary and secondary growth. There are two types of plant growth, and the stem plays an important role in both of them. Primary growth occurs in all groups when a plant grows taller and when it develops roots, branches, leaves, and flowers.
Secondary growth occurs when dicot stems and roots grow wider. Frequently, this involves the development of a woody stem, which arises from a combination of the activities of the stem’s vascular cambium and cork meristem tissues. However, not all dicots that undergo secondary growth have woody stems—for example, tomato, carrot, ...
This is similar to the function of the cambium in dicot roots. Within the vascular bundles, the xylem is located interior to the cambium ring, and the phloem is located exterior to the cambium ring, accompanied by sclerenchyma ground tissue. The ground tissue located interior to the cambium ring is referred to as the pith.
There is also a different type of pollen structure present in the two classes. Monocots developed from plants with a single pore or furrow in the pollen, whereas dicots developed from plants with three furrows in their pollen structure.
Monocot. Embryo. As the name suggests, the dicot embryo has two cotyledons. Monocotyledons have one cotyledon in the embryo. Leaf venation. Leaf veins are reticulated (branched). Leaf veins are parallel. Type of leaves. Dorsiventral.
Flowering plants are divided into monocots (or monocotyledons) and dicots (or dicotyledons ). This comparison examines the morphological differences in the leaves, stems, flowers and fruits of monocots and dicots.
Dorsiventral. Isobilateral. Stomata in leaves. Some dicots are epistomatous i.e., they have stomata only on one surface on their leaves. Monocots are amphistomatous i.e., monocot leaves have stomata on both the upper and lower surface. Bulliform cells. Dicot leaves do not have bulliform cells.
Stomata. Stomata are pores found in the epidermis of leaves that facilitate gas exchange, i.e., the process by which gases move passively by diffusion across a surface. Monocot leaves have stomata on both their surfaces, but some dicots have stomata on only one surface (usually the lower one) of their leaves.
The classification of flowering plants or angiosperms into two major groups was first published by John Ray in 1682, and later by the botanist Antoine Laurent de Jussieu in 1789, replacing the earlier classifications.
The vascular system is divided into a cortex and stele. Bundles of vascular tissue scattered throughout the stem with no particular arrangement, and has no cortex. Pollen. Pollen with three furrows or pores. Pollen with a single furrow or pore. Presence or absence of wood. Both herbaceous and woody. Herbaceous.
Also, different from monocots is the roots of dicot plants originate from the radicle. Another way dicots are distinct from monocots is their flowers and flower parts are arranged in multiples of four or five . In addition, the cross section of a dicot stem shows the vascular bundles arranged in a circular pattern.
Monocot plants have one cotyledon. They also have long narrow leaves with parallel veins. Cutting a cross section from the stem of a monocot shows the vascular bundles scattered around in the plant tissue. The young plant stores food in the form of starches and other nutrients in a structure called the endosperm.
Cotyledons may last only a few days after the seed germinates (ephemeral) or last up to a year (persistent). Monocots and dicots differ in several ways which help in their identification and understanding of their origins. Paleobotanists, scientists who study the origins of plants, hypothesize that dicotyledons evolved first, ...
Dicots. As opposed to monocots, dicots (also called eudicots) have two cotyledons during germination which supply the young plant with food and nutrients. The leaves of dicot plants come in a variety of shapes and sizes and the veins form branching patterns.
Last Updated: April 24, 2019. Angiosperms are plants that live on land and reproduce using seeds in flowers and fruits. Monocotyledons and dicotyledons, also known as monocots and dicots, respectively, are two types of angiosperm plants. The Italian physician and biologist Marcello Malpighi (1628 – 1694) was the first to use the term cotyledon ...
