Life cycle entails the course of development of an organism, i.e. from the time of inception to growth to finally maturity when an organism can viably produce another of its kind. In certain organisms, life cycle includes the different generations of species.
What’s a life cycle of an organism?
A life cycle is defined as the developmental stages that occur during an organism’s lifetime. In general, plants and animals go through three basic stages in their life cycles, starting as a fertilized egg or seed, developing into an immature juvenile, and then finally transforming into an adult.
What is life cycle simple definition?
A life cycle is a course of events that brings a new product into existence and follows its growth into a mature product and eventual critical mass and decline. The most common steps in the life cycle of a product include product development, market introduction, growth, maturity, and decline/stability.
What is life cycle example?
The definition of a life cycle is the series of changes that happen to a living creature over the course of its lifetime. An example of life cycle is a caterpillar turning into a butterfly. A progression through a series of differing stages of development.
Why do organisms have life cycles?
individual organisms die, new ones replace them, which ensures the survival of the species. During its life cycle, an organism goes through physical changes that allow it to reach adulthood and produce new organisms. Since these changes are common within a species, they can be grouped into stages of development.
What are the stages of life cycle?
The major stages of the human lifecycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years. Proper nutrition and exercise ensure health and wellness at each stage of the human lifecycle.
What are the types of life cycle?
A life cycle is a period involving one generation of an organism through means of reproduction, whether through asexual reproduction or sexual reproduction. In regard to its ploidy, there are three types of cycles; haplontic life cycle, diplontic life cycle, diplobiontic life cycle.
What is life cycle answer?
A life cycle is a series of stages a living thing goes through during its life. All plants and animals go through life cycles. It is helpful to use diagrams to show the stages, which often include starting as a seed, egg, or live birth, then growing up and reproducing. Life cycles repeat again and again.
What is a life cycle short answer?
Life cycle means the stages a living thing goes through during its life. In some cases the process is slow, and the changes are gradual. Humans have various stages of growth during their lives, such as zygote, embryo, child and adult. The change from a child to an adult is slow and continuous.
What is the life cycle of fish?
The life cycle of marine fishes is comprised of four developmental stages: egg (or embryonic), larval (yolk-sac and non-yolk-sac), juvenile and adult. The eggs and larvae of marine fishes are called ichthyoplankton.
What is a butterfly’s life cycle?
There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.
What are the 2 phases of life cycle?
Explanation: Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures.
How are organisms life cycle different?
All living things (organisms) have a life cycle. They are born, grow up, reproduce and die. Different groups of organisms (species) have different kinds of life cycles. Yet the life cycle of an insect is very different from the life cycle of a mammal or a reptile.
What is the difference between plant and animal life cycle?
Life Cycle of a Plant: Plants start as seeds, then most form flowers and fruit. Plants start as seeds. Life Cycle of an Animal: Animals start from eggs or live birth, then they grow up and mate. Animals begin life either from an egg or as a baby that is born ready for life.
