A sex organ (or reproductive organ) is any part of an animal's body that is involved in sexual reproductive organs together constitute the reproductive testis in the male, and the ovary in the female, are called the primary sex organs. All others are called secondary sex organs, divided between the external sex organs—the genitals or genitalia, . ADVERTISEMENTS: In this article we will discuss about the anatomy of equisetum. Also learn about its spore-producing organs. Cut thin transverse sections of different plant parts, stain in safranin-fast green combination, mount in glycerine and observe the anatomical details: T. S. Internode of Aerial Sterile Shoot: ADVERTISEMENTS: In a cross-section following structures . The conception of human life and the propagation of the species has long been a subject of curiosity in all civilizations. Although much is now known about the biology of reproduction, a great deal remains to be discovered about the diseases and disorders that can damage the reproductive system. Ethical concerns surrounding the issues of birth control and Reviews: 2. Horsetail (Equisetum) Mature Strobilus. Horsetails (Equisetum arvense) are hollow-stemmed plants that anchor deep into the ground by an extensive, creeping root system. Also commonly known as mare's tail, horse pipes, or snake grass, their origins reach far back into the past, some million years.
The reproductive system or genital system is a system of sex organs within an organism which work together for the purpose of sexual non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. Unlike most organ systems, the sexes of differentiated species often have significant : , The female reproductive system is made up of the internal and external sex organs that function in reproduction of new humans, the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and to carry a foetus to full internal sex organs are the uterus, Fallopian tubes, and : 1. Add the following labels to the diagram of the male reproductive organs below. testis | epididymis | vas deferens | urethra | penis | scrotal sac | prostate gland. Diagram of Male Reproductive System with labels added 2. Match the following descriptions with the choices given in the list below. Scouring rush (Equisetum hiemale L.) and horsetail (Equisetum arvense L.) are known to have high Si and Takahashi (a) investigated the response of these two plants to Si. As shown in Figure and Table , Si -deficiency significantly reduced the growth of both Si uptake during a period of 24 h by both plants was not affected by transpiration .
What are Trophorestorative? The "Trophic" state is representative of the vital capacity of a system or tissue in the body. Often these herbs have tissue specificity within the body, such as endocrine, skin, lungs, heart, stomach and female reproductive organs. How do Trophorestoratives Work? In chronic states of irritation or depression, some degree of vital deficiency will. Plant reproductive system - Plant reproductive system - Physiology of plant reproduction: The maturation of sporophytes and gametophytes, as manifested by their ability to produce spores and gametes, respectively, involves both internal and environmental factors. With respect to the former, the organism must have completed a certain minimum period of vegetative . Introduction to the Reproductive System. The major function of the reproductive system is to ensure survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for survival of the individual. An individual may live a long, healthy, and happy life without producing offspring, but if the species is to . Animal reproductive system - Animal reproductive system - Arthropods: The phylum Arthropoda includes a vast number of organisms of great diversity. Most arthropods are dioecious, but many are hermaphroditic, and some reproduce parthenogenetically (i.e., without fertilization). The primary reproductive organs are much the same as in other higher invertebrates, but the .
