Fertilization
Plants can be self-fertile or require a pollinator plant. Cross-fertilization occurs with plants that rely on a pollinator plant.
When planning a fruit tree purchase, it is important to know whether the plant is self-fertile or whether it requires a pollinator. If a plant is self-fertile you need only one tree of that kind to produce fruit. If a plant requires a pollinator, you will need two trees to get fruit.
Super simple plant anatomy
PLANTS, WHETHER TINY HERBS OR GIANT TREES, are basically made up of three parts: roots, stems, and leaves. Roots are the parts growing downwards into the ground. They take in part of the plant's nourishment, including water, from the soil, and they anchor the plant into the soil. Roots usually branch many times as they grow. The smaller branches are called rootlets.
Growing upwards from the roots is a stem. At certain places along the stem, according to plant type, there are leaves. Leaves, as a group, make up the plant's foliage. The stem acts as a conduit, carrying nourishment from the roots to the leaves. Leaves also take in food from the air. These nutrients, along with the nutrients transferred to the leaves from the root system, begin to change within the leaves. When exposed to sunlight, the nutrients change into a form that the plant can actually use for its health and growth. This process is called photosynthesis.
A healthy growing plant extends its roots and rootlets further and further out into the soil. Reaching out lets it have access to more soil nutrients and more water. Meanwhile, in a healthy plant, the stem becomes longer. It develops more leaves, or sends out more branches, which in turn develop more leaves. The many leaves obtain more light and air, aiding plant nutrition. Your job as a gardener is to help each of your plants meet its growth needs.
• Each male stamen consists of an anther and a filament, while the female pistil has three parts — a stigma, style, and ovary. When pollen lands on the stigma, pollination occurs.
