For example flowers. I know they rely on insects to pollinate but how do they actually procreate another flower?

Through spores..

If a plant has flowers then generally they rely upon sexual reproduction to reproduce, one of the many exceptions being the strawberry plant, which produces seeds as well as reproducing asexually.
Asexual reproduction is where the plant produces a clone of itself. It shoots out a runner, and on the end of the runner another plant is produced. The runner can then be broken and the new plant, which is the same as its parent, is able to survive on its own.
Also daffodils have flowers and yet they do not produce seeds. These are bulbous plants. Once pollinated, instead of producing seeds, the bulb splits to form another plant.
I'm not entirely sure if I'm spelling it properly but I have a plant with ribosomes/rhyzosomes called triangularis oxalis and it produces flowers. When the flowers have been pollinated, another ribosome/rhyzosome grows, which can be broken off and will grow a new plant. These odd little nodules are found at the base of the plant and act like bulbs but aren't the same shape or texture.
Is this what you were after?

The only seedless plants are moss and ferns, and they reproduce by spores, which are single-celled and they germinate just like a seed does. There are two kinds of seed plants, gymnosperms and angiosperms, the first being pines cycads, etc, plants without fruits or flowers. All flowering plants have seeds, and what happens is something like this: either an insect of the wind pollinates a flower, the ovary is modified to produce a fruit, inside which will be a seed. The seed then germinates and creates a plant that will have flowers.

One of the special things about plants is that many of them can vegetatively reproduce - this means that they can reproduce on their own (asexually), commonly by underground roots that grow out away from the plant and a new plant will spring up from it (eg. mint and daisies do this), or through humans as cuttings etc. (eg. many gardeners do this). Some plants also grow new baby plants on their leaves that drop when they are big enough and can grow on their own (eg. mangroves do this), and also by using special hormone treatments, scientists can make new plants out of only a few cells from a parent plant. However, these forms of asexual reproduction are not technically considered to be reproduction because the new plants are genetically identical to the parent (ie. they are clones of it) so we say they are part of a genet instead - this is a group of plants that are able to grow independently from each other but are genetically identical.

However, there are ways to reproduce without seeds and pollen. It's only flowering plants (angiosperms) that produce true seeds. These are common but evolved relatively recently. Plants like ferns, palms, and mosses use a different type of reproduction involving spores. Generations of these plants are really different to ours as they have 2 stages - one where male and female plants mate and one where a new kind of plant reproduces with its self - very complicated!

But what about seedless fruits? We can easily buy these - eg. seedless grapes or bananas. These varieties grow flowers that are pollinated and intend to reproduce sexually, but do not produce seeds because they have been genetically manipulated not to - fruits develop but seeds do not. Wild bananas and grapes always produce seed or the species will not survive more than one generation, but in agriculture cuttings can be taken and used to grow new plants. Remember these plants are clones - there are only 7 genets of commercial banana grown in the world, ie. all bananas are clones of one of only 7 parent plants!

but most flowers produce seeds, very few don't. Most of the non flowering plants are things such as ferns, which use spores. The rest have other methods, such as branches that droop to the ground where they will root and create other plants. There are some that have been selectively bred that are sterile, so they don't produce viable seed, and they are produced on a commercial scale by cuttings, or using special media that allow them to develop a plant from just a few cells.

Uhhhh.... flowers produce seeds.

Other plants that don't produce seeds can spread in other interesting ways.
Firstly, roots can spread, and other 'suckers' can spring up from the same root system. This is what bamboo does.
Secondly, if low hanging branches become covered in soil, they can spring roots and become a new plant.
Thirdly, with the assistance of humans, you can take cuttings and plant the sticks in sand, and grow a new plant. This does't happen in the wild.

They do create seeds.
As far as I know there are only a couple of other ways. With bulbs like daffodils, new bulbs grow on the roots of the parent and spread that way.
Some other 'creeper' plants like ivy, rhododendron (sp?) product roots from branches when they are buried or touching the ground.

Most produce seeds though (some flwors make seeds as small as dust, so you can't always tell.

flowers do not produce flowers but the seeds & the food which give birth to a new plant where the process continue.
seedless plants reproduce by asexual means called vegetative propogation. it idludes: grafting, cutting,etc. there are also some methods such as braches reach uder soil and give rise to a new plant or roots such as that of banyan tree give rise to new plant without producing seeds.
runners are also the kind of plants that grow without seeds such as grass.

Plants are autotrophs; they make their own organic nutrients. The term "organic" refers to compounds that contain carbon. Organic nutrients such as sugars are made by photosynthesis.

Plants are adapted to living on land. For example, the above-ground parts of most plants are covered by a waxy layer called a cuticle to prevent water loss.

Aquatic plants are secondarily adapted to living in water.

The basic alternation of generations life cycle is illustrated in the following websites:

any plant that has flowers creates seeds. some plants use insects to transfer pollen to other flowers, some like conifers, use the wind to transfer pollen
Plants without seeds have spores - mushrooms and fungi, ferns.
