Question

Name any two features on the basis of which you will categorise any plant a monocot or a dicot plant.

Answer 1

Any plant can be categorized as either monocot or dicot based on the following feature: (any two)

1. Seed - Monocot seed has one cotyledon and dicot seeds have two cotyledons.

2. Roots - Monocots have adventitious roots, whereas instead of roots dicots have radicle from which a root develops.

3. Stem - Monocot has weak stem whereas dicot has a strong stem.

4. Leaves - Monocot doesn't have stalk ie., it is attached directly with the stem, whereas dicot has stalk i.e., leaves attached to stem via a stalk.

5. Veins - Monot plant leaves have parallel veins that are long and thin, whereas dicot plant leaves have branched veins.

6. Cells - At a microscopic level, they have different shapes of guard cells and in case of dicots, they are abundantly present on the lower side of a plant.

7. Monocots have bulliform cells on leaf surface whereas they are absent in dicots. Bulliforms are large bubble-shaped cells that grow in clusters or groups on the surface.
