Determine which of the following plants are monocots and which of them are dicots.
pansies
hydrangeas
sunflowers

The answer is that all of them are dicots.

The angiosperms are the flowering plants. They are divided into two classes - the dicots and monocots. The monocots have one cotyledon in the seed while the dicots have two cotyledons in the seed. However, if we cannot assess the number of cotyledons, we can look at some morphological characteristics of monocots and dicots:

- The monocots have petals in multiples of three. The dicots have petals in multiples of four of five.

- The monocots have parallel leaf vein. The dicots have reticulated leaf veins.

So, none of those flowers have petals in multiples of three and they have reticulated leaf veins. Therefore, they all must be dicots.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
