1. In an albuminous (endospermic) seed, the primary food storage tissue for the developing embryo is the:

2. What is the name of the single, shield-shaped cotyledon in a grass (monocot) embryo, like maize?

3. During epigeal germination, which part of the embryo elongates rapidly to push the cotyledons above the soil surface?

4. In hypogeal germination, which embryonic part elongates to bring the plumule out of the soil while the cotyledons remain underground?

5. Besides water absorption, what other crucial function does the micropyle perform during the initial stages of germination?

6. The process of physically damaging the seed coat to allow water absorption and break dormancy is known as:

7. What type of enzymes are activated during seed germination to break down complex stored food (like starch, proteins, fats) into simpler, soluble forms?

8. Which physiological process within the germinating seed immediately utilizes the mobilized food reserves to provide energy for cell division and growth?

9. Seeds like those of cotton, milkweed, and dandelion are adapted for dispersal by wind due to the presence of:
