Plant Reproduction and Development Quiz

Angiosperms are vascular plants that develop flowers and represent 85 percent of land plants. They are important domesticated plants.

Asexual reproduction in plants does not involve fertilization and results in clones, which are identical copies of the parent plant. It is achieved by mitotic cell division and occurs in a variety of structures and mechanisms.

Sexual reproduction in plants is based on meiosis and fertilization. Meiosis is a type of cell division that produces daughter cells containing half the number of chromosomes, while fertilization is the fusion of haploid cells termed gametes. Meiosis and fertilization occur in alternate phases of the plant's life cycle.

<p>Land plants have a life cycle with two distinct multicellular forms: the diploid phase, called sporophyte, and the haploid phase, called a gametophyte. Sexual reproduction is characterized by meiosis and fertilization occurring in alternate phases of the life cycle.</p> Signup and view all the answers

<p>Flowers are reproductive structures in angiosperms that produce gametes, attract pollinators, receive gametes from others, nourish embryos, and develop seeds and fruits, thus playing a crucial role in the sexual reproduction of angiosperms.</p> Signup and view all the answers
