Seeds definitions Flashcards

The process where a sperm cell from pollen unites with an ovule in a flower, leading to the formation of a zygote that will develop into a seed and eventually a new plant.

The process by which a fertilized egg (zygote) develops into a multicellular plant embryo within a seed, involving cell division, differentiation, and formation of primary meristems.

The initial cell formed after the fertilization of an ovule by sperm, which divides to form the plant embryo and supporting structures.

A cell derived from the zygote that forms the suspensor, a structure supporting the developing plant embryo.

Embryonic leaves in seeds that provide initial nutrients to the developing plant; their number distinguishes monocots (1) from dicots (2).

Plants with a single embryonic leaf (cotyledon), parallel leaf veins, scattered vascular bundles, fibrous roots, and floral parts typically in multiples of three.

Plants with two cotyledons in their seeds, characterized by net-like leaf venation, flower parts in multiples of four or five, and vascular bundles arranged in a ring.

The embryonic stem segment between the radicle and cotyledons, crucial for seedling emergence and initial growth.

Embryonic root of a plant that emerges during germination, anchoring the seedling and absorbing water and nutrients for growth.

Nutrient-rich tissue in seeds that provides essential nourishment to the developing plant embryo during germination.
