The life cycle of angiosperms, or flowering plants, features an alternation between diploid sporophytes and haploid gametophytes. These plants are known for their complex structures, including roots, shoots, and specialized tissues that enable them to adapt to various environments. Their reproductive process is highlighted by the flowers' role in gamete production and the unique phenomenon of double fertilization, which results in both a zygote and a triploid endosperm. This cycle contributes to the diversity and success of angiosperm species.

The dominant form of angiosperms, visible as the mature plant, that produces haploid spores through meiosis
Male and Female Gametophytes
The less conspicuous generation responsible for producing male and female gametes through mitosis
Tissue Types
The three types of tissue (dermal, vascular, and ground) that make up the gametophyte and have various functions
The alternation of generations is a crucial aspect of the angiosperm life cycle, allowing for reproduction and lifecycle continuity
The below-ground system that provides stability, absorbs water and minerals, and stores food
Components
The above-ground system consisting of stems, leaves, and flowers that support the plant, carry out photosynthesis, and facilitate reproduction
Tissue Types
The three types of tissue (dermal, vascular, and ground) that make up the shoot system and have various functions
The organization of the root and shoot systems allows angiosperms to thrive in diverse environments
The primary reproductive structures of angiosperms that contain both male and female gametophytes
Specialized Tissues
The protective dermal tissue, nutrient-transporting vascular tissue, and multifunctional ground tissue that support the reproductive organs
Meristematic Tissue
The undifferentiated cells that play a crucial role in plant growth by continually dividing and giving rise to various plant tissues
The process of pollen from the anther being transferred to the stigma of a flower, leading to the formation of a diploid zygote
The unique process in angiosperms where one sperm fertilizes the egg, forming a zygote, and another sperm fuses with two polar nuclei to form the triploid endosperm
The formation of seeds, protected by fruits, that aid in their dispersal and contribute to the widespread success and diversity of angiosperm species
