- cellulose, lignin, and pectin
- proteins, oils, and starches (correct)
- minerals, water, and enzymes
- sugars, amino acids, and vitamins

Study Notes
Seed Development
- After double fertilization, each ovule develops into a seed.
- The ovary matures into a fruit, encapsulating the seeds and aiding in dispersal.
Nutrient Storage
- The sporophyte embryo develops from the zygote.
- The seed stores proteins, oils, and starches, initially within the endosperm.
- In some species, nutrient storage shifts to the cotyledons (seed leaves) of the embryo.
Completion of the Life Cycle
- Upon germination, the embryo grows into a new sporophyte.
- The mature sporophyte produces flowers and fruits, completing the angiosperm life cycle.
