Answer:
1 . annual: A plant that completes its life cycle within a year's time
2 . dicotyledon: A flowering plant with seeds having two seed leaves
3 . cotyledon: A seed leaf
4 . entropy: A running down
5 . endosperm: A food storage tissue
6 . monocotyledon: A flowering plant with seeds having one seed leaf
Explanation:
Annuals are plants that grow, reproduce, and die in one year or less. These are mostly herbaceous plants. Some of the examples of annuals are corn, geranium, and marigold.
Flowering plants are categorized as dicotyledons and monocotyledons based on the number of seed leaf present in their seeds. The dicotyledons have two seed leaves in their seeds while monocotyledons have only single cotyledon in their seeds. Here, cotyledons represent the seed leaf associated with the embryo within the seeds. The cotyledons may function as storage organs. They absorb the food reserves and become large, thick, and fleshy. Gram is a dicot plant while wheat and corns are examples of monocots.
A mature seed of flowering plants has an embryonic plant and food reserved. These food reserved may be present in the form of cotyledons and/or endosperm. The endosperm is a nutritive tissue and is triploid in flowering plants.
Entropy represents the energy of a system that can not be used to perform any task. This energy rather makes the system random or unorganized. During energy transfer, the part of the energy lost as heat represents entropy.
