Why are flowers important to the life cycle of some plants but not others?

The answer lies in the phylogeny of Plant Kingdom. To begin with plants had gametophytic plant body and sporophytic stage was dependent on gametophytic stage. As the evolution progressed the gametophytic stage became dependent on sporophytic stage and further evolution resulted in the formation of flowers sothat seeds may be formed to overcome the adverse climates.

∙ 9y agoJust as in animals there are stages in the process of evolution that has culminated in the evolution of man.
In the plants also there are similar stages in the process of evolution and the process has culminated in the formation of flowering plants.The major stages are as follows:-
1)The Thallophytes- The plant body has no roots stems and leaves. Reproduction by different means;but never by means of flowers. Examples are all Algae and all fungi.
2) The Bryophytes - The plant body may show root like , stem like and leaf like organs but not always and these are not true roots,stem, and leaves.No flowers are produced.Examlpes are Mosses , Liverworts and their relatives.
3) The Peridophytes - For the first time the true roots, stem and the leaves appear in this group as they are the pioneer land plants.Sill no flowers are produced.Ex.- Ferns, Lycopods and the Horse tails.
4) The Spermatophytes - The roots , stem and the leaves are well established in this group.These are the true FLOWERING & SEED BEARING PLANTS ( Spermos = seed, don't confuse with sperm which is the male gamete.)They have two major sub groups viz. Gymnosperms and Angiosperms
A) Gymnosperms- ( Gymnos = naked; Spermos = seed.).
i)They do produce flowers; but they are not at all atractive and for a lay man they do not appear like flowers.
ii) They do produce seeds but they are not enclosed in side a fruit as there is no frut formation ( Due to absence of an ovary).So Gymnosperms = Naked seeds. Examples = The Conifers like Pinus and the members of red wood forests; The X'Mas Tree. Cycas of the deserts and many more.
B) Angiosperms - This is the most highly evolved group.In these flowering plants the seeds are ALWAYS enclosed inside a fruit (Angion = A vessel or a container; Spermos = Seed.).The fruit and seed formation is on a regular basis, as an ovary is always present. Most of the time flowers are attractive to man as well as insects and birds! No examples are needed.

When do flowers bloom?
Flowers are part of a plant's life cycle; it is the basis for reproduction for many types of plants.The first flowers appeared so long ago, no human was there to check the date.Answer:Fossil evidence indicates that flowering plants diverged from gymnosperms around 245-202 million years ago.The first flowering plants were present 140 million years ago.
How is the life cycle of an evergreen tree similar to the life cycle of a flowering plant?
It's not because flowers wither and come back when trees stay green all year.:)

Nitrogen needs to be fixed before it is used by plants.

Why are plants important to the water cycle?
plants purify the earths water.
When do you need plants?
yes, plants are very important to the human life for the reperatoin cycle or the oxygen and carbon cycle.
Why are bees important for plants?
Bumblebees are extremely important to the plant life-cycle. This is because they play a vital role in pollinating plants by spreading the pollen from one plant to another, ensuring that the plant can reproduce. Without bumblebees to pollinate plants, it would be very difficult to grow a lot of the foods we have come to rely on such as tomatoes, apples and cucumbers.
Why does the water cycle play an important role in the environment?
The water cycle plays an important role in the environment. This cycle recycles the water in the system for the plants and animals.
