Sexual vs. Asexual Reproduction Living things use lots of different strategies for producing offspring, but most strategies fall neatly into the categories of either sexual or asexual reproduction. Asexual reproduction generates offspring that are genetically identical to a single parent.
Budding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas.
Fragmentation or clonal fragmentation in multi cellular or colonial organisms is a form of asexual reproduction or cloning in which an organism is split into fragments. Each of these fragments develop into mature, fully grown individuals that are clones of the original organism.
Pollen is a fine to coarse powdery substance comprising pollen grains which are male microgametophytes of seed plants, which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of coniferous plants.
selfing A method of seed generation in which pollination is performed manually and the pollen donor and egg donor are from the same plant. Selfing and Outcrossing Most flowering plant species reproduce primarily by outcrossing, including the great majority of trees, shrubs, and perennial herbs.
A fruit is a ripened ovary (or compound ovary)… A brief treatment of fruit follows. For information on particular fruits, see apple, banana, orange, peach, and so on. For treatment of the fruit as a reproductive structure, see seed and fruit. For treatment of the cultivation of fruits, see fruit farming.
Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur. In seed plants, the offspring can be packaged in a protective seed, which is used as an agent of dispersal.
Vegetative reproduction in plants is defined as a type of asexual reproduction, wherein the vegetative parts, like roots, stem and leaves give rise to new plants. This mode of vegetative propagation or vegetative reproduction is associated with certain advantages and disadvantages.
