Endosperm

Emergence of the embryonic axis

Embryonic axis and one or more cotyledons

Break down molecules into smaller units and release energy

Construct molecules from smaller units

Allow organisms to grow, reproduce, and maintain their structures

Catabolism breaks down molecules, while anabolism constructs molecules

By facilitating the physical and chemical processes inside the cells to maintain life

Study Notes

The seed coat, also known as the testa, functions to protect the seed from mechanical damage, drying out, and pathogens.
In monocotyledon seeds, the cotyledon is much reduced and modified to form the scutellum.
The radicle emergence marks the end of the process of imbibition during seed germination.

Catabolism is the process of breaking down complex molecules into simpler ones, releasing energy in the process, and its role in metabolism is to release energy for cellular activities.
Anabolism is the process of building up complex molecules from simpler ones, requiring energy, and its primary function in metabolism is to synthesize new molecules and maintain cellular structures.
The main purpose of metabolism in living organisms is to convert energy and nutrients into the components that make up living cells.
The key difference between catabolism and anabolism is that catabolism breaks down molecules to release energy, while anabolism builds up molecules requiring energy.
Metabolism contributes to the maintenance of life in living organisms by providing energy, synthesizing new molecules, and maintaining cellular structures.
