Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation.
The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation.
The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.
The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle.
This is much easier to understand if you see a diagram.

How many stages are in the life cycle of a seed plant?
The life cycle of a seed plant typically consists of two main stages: the sporophyte stage (where the plant produces spores through reproductive structures like flowers or cones) and the gametophyte stage (where the plant produces gametes through the process of fertilization).
How many stages does a plant life cycle have?
A plant life cycle typically has four stages: seed germination, growth and development, reproduction, and seed formation.
How would you describe the plant life cycle?
The plant life cycle is divided into two main stages: the sporophyte stage and the gametophyte stage. The sporophyte stage begins when a seed germinates and grows into a mature plant that produces spores. These spores develop into gametophytes, which produce gametes (egg and sperm) that combine to form a new sporophyte plant. This cycle repeats itself to perpetuate plant growth and reproduction.
What are the two alternating phases of a plants life cycle?
The two alternating phases of a plant's life cycle are the reproductive phase (gametophyte) where plants produce gametes, and the vegetative phase (sporophyte) where plants grow and develop. The gametophyte phase produces gametes through meiosis, which then fuse during fertilization to form a new sporophyte plant.
During the life cycle of a plant gametophyte is to n as sporophyte is to?
During the life cycle of a plant, gametophyte is to n as sporophyte is to 2n. Gametophyte produces haploid gametes through mitosis, which fuse during fertilization to form a diploid zygote that develops into a sporophyte through mitosis.
What are the two major stages of a plant life-cycle?
The Sporophyte stage and the gametophyte stage
What are the stages of life cycle of a flowering plant?
the stages of flowering plant's life cycle starts as a seed then the seedling,mature plant and finally death.
How many stages of plant life are there?

What are the two dominant life stages of a plant?

What is the life cycle of a string bean plant?
The life cycle of a string bean plant has four stages. These stages are, seed, germination, leaf growth, and flowering.
How many stages does a plant life cycle have?

The stages through which a plant or animal goes in its life?
life cycle
Life cycle of a bean plant?
4 stages.
Stages through which a plant or animal goes in its life?
Plants go through stages of seed germination, growth, reproduction, and death, while animals go through stages of birth, growth, reproduction, and death. These life stages are essential for the survival and continuation of each species.
What are the stages of a flowering plant's life cycle?
the stages of flowering plant's life cycle starts as a seed then the seedling,mature plant and finally death.
What plant has the same number of stages in its life cycle as the lady's finger plant?
the balsam and cucumber plant
