And just like us, these products have a life cycle. Older, long-established products eventually become less popular, while in contrast, the demand for new, more modern goods usually increases quite rapidly after they are launched. Because most companies understand the different product life cycle stages, and that the products they sell all have a limited lifespan, the majority of them will invest heavily in new product development in order to make sure that their businesses continue to grow.
The Life cycle will sprout and produce a tiny, immature plant called a seedling. The seedling will grow to adulthood and form a mature plant.
The mature plant will reproduce by forming new seeds which will begin the next life cycle. As described above this life cycle is generally used by the flowering plants.
The flowering plants include trees, grasses, shrubs, and, of course, flowers. There are also lower types of plants including ferns and mosses. These also have a life cycle but they do not produce seeds.
They produce a different type of reproductive cells called spores. In the flowering plants, there are male and female structures inside the flower.
These produce the seeds. A more detailed explanation and examination of seeds is found in the Bean Plant Activities section. It is instructive to examine flowers and seeds of various plants in order to study and learn their Life cycle and differences.
It is also necessary to study ferns and mosses and compare them with the flowering plants. Flower study Materials various flowers or pictures of flowers Note: The students should be aware about flowers if they are allergic to them or if they have asthma. In cases where the presence of pollen and flowers in the classroom raises health issues, it is better to use pictures.
Science Journals Procedure 1. Students brainstorm in class about what plants are included in the term flowering plants. Their suggestions and discussions are written on the board and in their Science Journals. They learn that in addition to common flowers, the flowering plants include trees, shrubs and grass plants.
Students examine pictures of flowers.
Flowers have various parts which can be studied. An example is shown below. They learn the different parts by completing a definition table as suggested below.
Flower Part What the flower part does Stamen The stamen is the male part of the flower. It produces pollen which fertilizes the immature seeds. Pistil The pistil is the female part of the flower. It contains the immature seeds. After the immature seeds are fertilized they become the seeds which produce the next cycle of plants.
Petal Many flowers have petals which have bright colors to attract insects. The insects carry pollen which fertilizes the immature seeds.
Sepal The sepals appear like small green leaves. They are protective structures used when the flower is not completely developed in the bud stage. Receptacle The receptacle supports the flower on the end of the stalk. Students note differences between different types of flowers. Some flowers have sepals and petals that look the same.
The gladiolus flower is an example. The sepals are colored the same as the petals and do not appear like small green leaves.
Trees have flowers but they do not resemble the flowers usually displayed in flower shops. Tree flowers do not have the bright petals because trees do not use insects for pollination.
They rely on the wind so there is no need to attract insects. Corn plants have tassels at the top of the plant which produce pollen. They have silks which are connected to the ears of corn.Life cycle, in biology, the series of changes that the members of a species undergo as they pass from the beginning of a given developmental stage to the inception of that same developmental stage in a subsequent generation.
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state.
"The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual.
Eventually, however, the hydrogen fuel that powers the nuclear reactions within stars will begin to run out, and they will enter the final phases of their lifetime.
Coupling Stage. The next stage in the family life cycle may be coupling. Using qualities such as trust that you gained in the independence stage, you can explore your ability to commit to a new family and a new way of life.

A bee, very much like a butterfly, undergoes four stages to complete one life cycle. In chronological order, they are egg, larva, pupa and adult.
