The filament is a stalk that holds the anther up. The anther produces the pollen. Each anther is made of microsporangium that contain diploid microsporophytes. These microsporophytes divide by meiosis and produce microspores that will then be haploid. The microspore then develops into a pollen grain made up of the male gametophyte and a surrounding pollen wall. This wall will protect the pollen grain as it is transported.
The male gametophyte contains two haploid cells. One is called a generative cell. This cell will divide to form two separate sperm. The other cell is called the tube cell and it will produce a pollen tube. Megasporangia produce megaspores which then will give rise to the female gametophyte. Protecting the megasporangium is a layer of sporophyte tissue called the integument.
The megasporangium, megaspore and the integuments as a whole is called the ovule.

As with all living organisms, the olive has its own growing cycle — from dormant period to birth sprout , to infancy flower buds , to juvenile fruit , to adult olive ripe , and finally to death harvest.
Because olives are renewable, the olive growth cycle begins again every spring. For the olive life cycle to run full circle, various external and internal conditions must be favorable for the olive tree. For instance, the olives require adequate space, water, nutrients, and enough sunlight for their successful growth.
Olive trees grow best in subtropical zones. However, even with great conditions, various stresses such as insects, diseases, weather, and time itself weaken the olive tree and can cause olives or the tree itself to die. Although an olive growth cycle may be stopped at any time for many different reasons, a new growth cycle can begin again next spring.
At first, there is a dormancy period for 1 — 3 months in the olive growth cycle. This is the time when olive tree rests after the harvest season-ending January and collects the energy and recourses to start a new olive life cycle. Olive trees need a cool, dry climate during winter to go dormant and produce new buds following with blooms needed for fruiting. In February, after the olive tree has been pruned, the floral induction begins.
As a result, new sprouts begin to grow and covers all the olive tree. Please bear in mind, the sprout season may start even later, depending on your climate zone. But here is described an olive growth cycle around the Mediterranean coast. Later in March, you can spot flower buds appearing on evergreen olive trees see an image in the infographic below. This is the start of the olive flowering season in May.

Overall, it takes around 3 months to build up an olive fruit. Finally, olives reach their last stage in the growth cycle in October. And the olives start to mature and ripe until they are ready for the harvest in early December up to the end of January. For example, the green color is unripe young olive. There as the dark purple or black is ripe olive.
Olives grow on the olive trees planted in the ground in warm temperate climates or indoors in containers or pots in cooler climates.

Once approved, it will be added to Wikifarmer. This destroys the viability of the seeds, even if they have not been removed from the fruit. It is recommended that you pick undamaged, ripe fruit from the tree.
It should be selected while it is still a green color, not yet turned black. Place the fruit in a bucket and cover with water. Bruise the fruits until the encasing shell is lightly broken, but not hard enough to break the pits. Soak overnight, stirring occasionally.
Clean all the fruit off the pits and nick the ends of each pit with a pair of clippers. Be careful not to nick too deep as this will ruin the seed. Soak the seeds again for 24 hours in room temperature water.
Prepare a cold frame to receive the seed pots. Place each seed in an individual growing pot filled with a half and half mix of sand and compost. Put the pots in the cold frame.
