What are some key characteristics that distinguish between the monocotyledons and the dicotyledons?
What are some key characteristics that distinguish between the monocotyledons and the dicotyledons?
The characters which distinguish the classes.
| MONOCOTS | DICOTS |
|---|---|
| Flower parts in multiples of three | Flower parts in multiples of four or five |
| Major leaf veins parallel | Major leaf veins reticulated |
| Stem vacular bundles scattered | Stem vascular bundles in a ring |
| Roots are adventitious | Roots develop from radicle |
What do you mean by Monocotyledonous and dicotyledonous?
Flowering plants are divided into two groups – monocots and dicots. A monocot, which an abbreviation for monocotyledon, will have only one cotyledon and a dicot, or dicotyledon, will have two cotyledons.
What are two characteristics of monocotyledons?
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.
What are two characteristics of dicotyledons?
Comparison with monocotyledons
| Feature | In monocots | In dicots |
|---|---|---|
| Number of furrows or pores in pollen | One | Three |
| Number of cotyledons (leaves in the seed) | One | Two |
| Arrangement of vascular bundles in the stem | Scattered | In concentric circles |
| Roots | Are adventitious | Develop from the radicle |

What is monocotyledons in biology?
Monocotyledons (/ˌmɒnəˌkɒtəˈliːdənz/), commonly referred to as monocots, (Lilianae sensu Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon.
Do dicotyledons have broad leaves?
dicotyledon, byname dicot, any member of the flowering plants, or angiosperms, that has a pair of leaves, or cotyledons, in the embryo of the seed. Most common garden plants, shrubs and trees, and broad-leafed flowering plants such as magnolias, roses, geraniums, and hollyhocks are dicots.
What are dicotyledons give two examples?
Dicotyledons or Dicots are a group of plants of Angiosperms whose seeds have two cotyledons… Examples : Bean , pea , mango , tomato , potato , groundnut etc…
What are examples of dicotyledonous plants?
Examples of dicotyledonous plants are beans, buttercups, oaks, sunflowers, etc. The angiosperms (the flowering plants) can either be a monocotyledon (or monocot) or a dicotyledon (or dicot) according to the number of cotyledons in their seeds (which in the case of dicots the cotyledons are two, hence the name).
What are dicotyledons give any two examples?
Peas, almonds and cashews are examples of dicotyledonous or dicot seeds. Dicotyledons are also known as dicots. They are the groups into which all the flowering plants or angiosperms were formerly divided. The name dicotyledons refer to the seed having two embryonic cotyledons.
