Answer 1

Grass is a monocot, the rest are dicots. The quickest way to tell the difference is to look at the plant's leaves. For more about these two groups, visit:

Answer 2

grass is not.

Monocots include grasses, sedges, lilies, orchids and onions. The arum family (jack-in-the-pulpit, Caladium, Spathiphyllum, Philodendron, Anthurium) are monocots, but often have broad leaves with netted veins. Palm trees are monocots, but they don't make proper wood and don't increase in girth like broadleaf trees. They are like a giant corn plant.

Dicots include broadleaf trees, shrubs, most flowers, and vegetables. Dicot or dicotyledon refers to flowering plants which at the time of germination have two cotyledons or embryonic seed leaves. Synonyms of Dicot include dicotyledon, magnoliopsid and exogen.
