2. Voronoi diagram - Wikipedia

   en.wikipedia.org/wiki/Voronoi_diagram

   Voronoi diagram. In mathematics, a Voronoi diagram is a partition of a plane into regions close to each of a given set of objects. It can be classified also as a tessellation. In the simplest case, these objects are just finitely many points in the plane (called seeds, sites, or generators). For each seed there is a corresponding region, called ...

3. Seed - Wikipedia

   en.wikipedia.org/wiki/Seed

   In botany, a seed is a plant embryo and food reserve enclosed in a protective outer covering called a seed coat (testa). More generally, the term "seed" means anything that can be sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote.

4. Vegetative reproduction - Wikipedia

   en.wikipedia.org/wiki/Vegetative_reproduction

   Vegetative reproduction. Production of new individuals along a leaf margin of the air plant, Kalanchoe pinnata. The small plant in front is about 1 cm tall. The concept of "individual" is stretched by this process. Kalanchoe daigremontiana produces plantlets along the margins of its leaves. When they are mature enough, they drop off and root in ...

5. Fibonacci sequence - Wikipedia

   en.wikipedia.org/wiki/Fibonacci_sequence

   In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn. The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from ...

6. Seedling - Wikipedia

   en.wikipedia.org/wiki/Seedling

   A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are ...

7. Double fertilization - Wikipedia

   en.wikipedia.org/wiki/Double_fertilization

   Double fertilization or double fertilisation (see spelling differences) is a complex fertilization mechanism of angiosperms. This process involves the fusion of a female gametophyte or megagametophyte, also called the embryonic sac, with two male gametes (sperm). It begins when a pollen grain adheres to the stigmatic surface of the carpel, the ...
