Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers , which are the reproductive structures of angiosperms , are the most varied physically and show a correspondingly great diversity ...
Adventitious buds form on roots near the ground surface, on damaged stems (as on the stumps of cut trees), or on old roots. These develop into above-ground stems and leaves. A form of budding called suckering is the reproduction or regeneration of a plant by shoots that arise from an existing root system.
The drawings are by Albrecht Meyer and the engravings by Veit Rudolph Speckle. Fuchs included ornamental plants and plants brought back from the Americas, and had the whole plants, including roots, flowers and fruits, illustrated from life so that they could be identified.
A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm.Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do not have a surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones.
The small plant in front is about 1 cm (0.4 in) tall. The concept of "individual" is obviously stretched by this asexual reproductive process. Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents.
These cones, especially the woody female cones, are considered the "archetypal" tree cones. The female cone has two types of scale: bract scale and seed scale (or ovuliferous scale), one subtended by each bract scale, derived from a highly modified branchlet. On the upper-side base of each seed scale are two ovules that develop into seeds after ...
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes , as well as facilitating fertilization and supporting the development and birth of offspring.
Pneumatophores (respiratory roots) – Part of tap-root system as respiratory roots; found in many mangrove trees. They arise from the thick, mature branches of tap-root systems, and grow upwards. The inner tissue of respiratory roots is full of hollow, airy, tube-like dead cells, giving it a spongy texture.
