No, generally speaking, all plants have to flower and bear fruit to reproduce offspring, pollination vectors include wind vectors (such as gramineae, sedges, pine and ginkgo, etc.), insect vectors, autoflowers (monoecious, dioecious), pollinating insects mainly include bees, flies, butterflies, moths, beetles. Bees are mainly honey bees and wall bees, which pollinate plants in the process of pollen and nectar collection. Flies are mainly aphid-eating flies, and sometimes they also feed on nectar for nutrition; Butterflies and moths mostly feed on nectar, pollinating in the process of sucking nectar, butterflies feed and pollinate during the day, and moths feed and pollinate at night. Scarabs pollinate when they feed on plant flowers, such as apples, pears, peaches, plums, cherries and apricots.

According to the condition of pistils and stamens, flowers can be divided into two types: in a flower, the stamens and pistils exist at the same time, which is called a hermaphroditic flower, such as the flower of peach and wheat. A flower that has only stamens or pistils is called a unisexual flower, such as the flower of a pumpkin or loofah.
The flowers that have only stamens are called male flowers; Those with only pistils are called female flowers. If the female flower and the male peanut are on the same plant, it is called monoecious, such as corn. If the female and male flowers do not grow on the same plant, they are called dioecious, such as mulberry.
Plants that rely on insect pollination are called insect-borne flowers and belong to unisexual flowers.

Everyone knows that plants are mostly pollinated by insects, but this plant is amazing, relying on bats!

<> self-pollination: that is, pollen falls from anthers to the stigma of the same flower, such as wheat, rice, cotton, soybean and other plants are mostly self-pollination.
Cross-pollination: that is, pollen falls from the anthers of one flower to the stigma of another flower, such as corn, peach and other plants are cross-pollinated.
The two most important mediums for cross-pollination are wind and insects. Flowers that rely on wind pollination are called wind-borne flowers; Flowers that rely on insect pollination are called insect-borne flowers.
Pollination is the process by which mature pollen is dispersed from stamens, anthers, or microsporangia to the stigma of the pistil or ovules. Pollination is a unique phenomenon of higher vascular plants, and male gametes are transported to female gametophytes through pollen tubes, so that plant fertilization is no longer mediated by water, which is of great significance for adapting to the terrestrial environment.
Under natural conditions, pollination includes both self-pollination and cross-pollination. Pollinators mainly include insects (including bees, beetles, flies and moths) and wind. Hummingbirds, bats and snails can also pollinate, and some plants pollinate through water.

Of course, after the seeds of the plants mature, they immediately break away from the mother tree, and after a period of dormancy, and then germinate into young plants in the soil under the conditions of suitable temperature, water and air. >>>More
Insect-borne flowers mostly have the following characteristics: >>>More
Strictly yes.
For example, when dividing organisms into two kingdoms, plants and animals, including algae, fungi, lichens, mosses, ferns, and seed plants; In the system of the Five Kingdoms, the plant kingdom includes only multicellular photoautotrophic taxa, while fungi, lichens, and unicellular algae, as well as prokaryotic cyanobacteria, are not included. >>>More
