Question

Dustuingish between monocoats and diocots based on the type of roots and petals of flower

Answer 1

HEY!!!
Comparison between Monocot and Dicot Plants

There are some specific characteristics that help us identify the plant as a monocot or a dicot. Let us look at them.

Seeds

Plant embryos in seeds have structures called cotyledons. A cotyledon is the central portion of a seed embryo to which the epicotyl (immature shoot) and radicle (immature root) are attached. The number of cotyledons differs in these two groups of plants and that forms the basis for the main classification of monocots and dicots.  A seed of a monocot plant has one cotyledon and that of a dicot plants has two cotyledons.   (Note: This is easy to remember when you know mono=one and di=two).

Roots

Roots can develop either from a main radicle that is one large taproot with many small secondary lateral roots growing out of it, or can be a fibrous mass of roots that arise from the nodes in the stem, called adventitious roots. Monocots have adventitious roots,  whereas dicots have a radicle from which a root develops.

Leaves

Leaves have more than one characteristic that help differentiate a monocot from a dicot. If the leaf has a stalk, then the plant is a dicot. But, in the case of a monocot plant, the leaf is sessile, which means it is attached directly by its base without a stalk.

The next characteristic that helps in the identification is the venation. If the leaves have parallel venations that are long and thin, then the plant is monocot. If the leaves have a branched venation, then the plant is a dicot.

Flowering Parts

Monocot flowers tend to have a number of petals or other floral parts that is divisible by three, usually three or six. Dicot flowers on the other hand, are likely to have parts in multiples of four or five (four, five, ten, etc.). This character is not always reliable, and is not easy to use in identification of some flowers with reduced or numerous parts.

Pollen Structure

Monocot and dicot plants have different pollen structures. In a monocot, the pollen grain produced by the flower has a single furrow or pore through the outer layer. In a dicot plant, the pollen grain has three furrows or pores.

Answer 2

monocots have fibrous roots where as dicots have tap root .
number of petals in monocots are generally multiple of 3 and number of petals in dicots are generally multiples of 5 .
