Answer 2

Answer is option d " longitudinal section"

Explanation:

• Different parts seen in the longitudinal section of bean seed and their functions are as follows:
• Cotyledons are the embryonic part of the seeds of flowering plant that store nutrients for baby plant. These are the first leaves produced by plants but are not true leaves. They feed plant till true leaves develop and begin photosynthesis.
• Radicle is the part of a seed embryo that develops into the root and helps in the absorption of water and minerals.
• Epicotyl – Upper portion of the axis of a seedling, above the cotyledons and below the next leaf.
• Seed coat actually protects the seed from any damage such as physical, temperature related or water damage.
• The outer layer of seed called testa prevents the seed from drying, freezing and some times from the effect of fire.
• Testa as an outer layer provides a time delay factor which take care of the right time for the germination of the seed.
