Apr 13, 2022 · Learn how scientists use sample size and reproducibility to develop experiments. Even a well-planned experimental inquiry can include variability and errors beyond the experimenter’s control. There may be small variations in environmental conditions or the experimenter may not take the most accurate readings.
Feb 10, 2022 · Plants reproduce in two ways: 1) sexual and 2) asexual. Sexual reproduction involves the participation of two parents. Here, offspring are produced by combining the genetic material of male and female sex cells or gametes through fertilization.
Oct 28, 2022 · Flowering plants reproduce sexually through a process called pollination. Flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. Pollen contains the male gametes. Pollen must be moved to a part of the pistil called the stigma for reproduction to take place.
In many plant groups, fragmentation of the plant body, followed by regeneration and development of the fragments into whole new organisms, serves as a reproductive system. It is common horticultural practice to propagate desirable varieties of garden plants by means of plant fragments, or cuttings.

Feb 2, 2017 · Scientists divide plants into two main groups depending on whether they reproduce by seeds or spores. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed.
