The larger, more familiar female cones of a gymnosperm which produce the female gametophyte.
The two things near the base of each scale on a gymnosperm seed cone where the female gametophytes develop. In them, meiosis produces haploid cells that divide to produce female gametophytes.
The sticky material secreted by female gymnosperms that catches pollen grains and ensures that they stay on the seed cone.
The structure which grows from a pollen grain which lands near an ovule, allowing it to fertilize the egg.
The outermost type of leaf in a flower which is often green and resembles ordinary leaves. Enclose the bud before it opens and protect the flower while it develops.
The type of leaf in a flower which is found just inside the sepals and is often brightly colored to attract pollinators such as insects to the flower.
The type of leaf in a flower which makes up the male part and produces the male gametophyte. Consists of an anther and a filament.
An oval sac at the tip of a filament where meiosis takes place, producing haploid male gametophytes (pollen grains).
The broad base on a carpel which contains one or more ovules where female gametophytes are produced.
Is it possible for a single angiosperm to have separate flowers on it to produce male and female gametophytes?
The eight nuclei and surrounding membrane contained within the ovule which form the female gametophyte of an angiosperm, or flowering plant.
A nutrient-rich tissue formed from the extra sperm nucleus and two polar nuclei in the embryo sac. It is a triploid (3N) cell and nourishes the seedling as it grows.
The name for the process where two fertilization events take place between the male and female gametophytes of an angiosperm.
The structure which provides protection and nutrition for the embryo and helps plants succeed on land.
A period during which an embryo is alive but not growing. The length of this period varies based on species. Environmental factors such as temperature and moisture can cause it to germinate.
The early growth stage of a plant embryo. They absorb water and swell, cracking the seed coat open.
The process in which some flowering plants reproduce asexually by mitosis alone, creating many genetically identical plants. It includes the production of new plants from horizontal stems, plantlets, and underground roots.
Cuttings, Grafting, and Budding
3 ways to produce identical copies of a plant or to produce offspring from seedless plants.
