Study Notes
Organisms reproduce using a variety of methods, depending on their classification. Plants utilize pollination, where gametes, usually sperm, move from male to female structures. Animals typically depend on fertilization, which involves males transporting sperm inside females to reach eggs for fertilization. Insects like butterflies rely on males providing chemicals called sex peptides that attract females. Fertilization in mammals takes place internally, while in birds, fertilization occurs externally followed by internal incubation of the egg. Sexual reproduction is common across many groups of organisms, ensuring genetic mixing.
Asexual reproduction, however, does exist. For instance, hydra and starfish can reproduce without fusing gametes, while fungi can clone themselves via mitosis. Different types of organisms employ distinct ways of reproducing, reflecting their evolutionary paths and specific requirements.
