Question

What are the seed leaves that provide energy for young seedlings of angiosperms called?

Answer 1

Angiosperms are vascular plants. They are made up of stems, roots, and leaves. Angiosperm seeds are found in a flower as opposed to gymnosperms such as conifers and cycads. Angiosperm’s ovum is grown and developed into seeds in an ovary, which is usually in flower.

Complete answer:
Cotyledons (seed leaves) are the essential in the undeveloped organism of higher plants that, upon germination, develop into the seedling's early stage first leaves.
The cotyledons are an important component of the developing organism inside the plant's seed. The food supplies of the seed are stored in the cotyledons. When these reserves are depleted, the cotyledons turn green and begin to photosynthesise.
They mostly shrivel away as the primary genuine leaves take over food production for the seedlings. Cotyledons can be present on the plant for a few days or for a year. Monocotyledonous species are those that have only one cotyledon ("monocots"). Dicotyledonous plants have two undeveloped leaves.
Because dicot seedlings' cotyledons are photosynthetic, the cotyledons are almost identical to leaves. Genuine leaves and cotyledons, on the other hand, are formatively unmistakable. Cotyledons are formed during embryogenesis, along with root and shoot meristems, and are then present in the seed prior to germination. Genuine leaves, on the other hand, are formed post-embryonically (for example, after germination) from the shoot apical meristem, which is in charge of producing the plant's resulting ethereal segments.
The cotyledon of grasses and numerous different monocotyledons is an exceptionally adjusted leaf made out of a scutellum and a coleoptile. The scutellum is a tissue inside the seed that is particular to ingest put away food from the adjoining endosperm. The coleoptile is a defensive cap that covers the plumule (antecedent to the stem and leaves of the plant).

Note:
Gymnosperm seedlings additionally have cotyledons, and these are regularly factor in number (monocotyledonous), with from 2 to 24 cotyledons framing a whorl at the highest point of the hypocotyl (the undeveloped stem) encompassing the plumule. Inside every species, there is regularly still some variety in cotyledon numbers, for example Monterey pine (Pinus radiata) seedlings have 5–9, and Jeffrey pine 7–13 , yet different species are more fixed, with for example Mediterranean cypress continually having only two cotyledons
