Answer:
1=Function of Plumule (shoot tip): The plumule is the part of the embryo that develops into the shoot bearing the leaves of the plant. The plumule gives rise to aerial shoots. The function of cotyledon: They store reserve food material or serve as photosynthetic organs in young seedlings.
2=An embryo is the early stage of development of a multicellular organism. In general, in organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs.
3=. In botany, a hilum (pronounced /ˈhaɪləm/) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). ... The adjectival form hilar denotes the presence of such a mark, and can be used as a distinguishing characteristic of a seed or spore........!!!!!
4=A microphone is the device responsible for transferring sound as it travels through the air, and converting it into electrical impulses that can be amplified by PA systems, or recorded by either analog or digital recorders.
5= Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.
