Hydra plain w.m.

" Various mounting techniques and staining processes -Identifying features clearly distinguishable -Rigorous quality control standards Hydra are in the phylum Cnidaria and are related to jellyfish and sea anemones. Research suggests that hydra are one of the few animals that maintain telomere length and do not go through cellular senescence. Therefore, they are biologically immortal.We offer a variety of individual Hydra slides demonstrating a range of structures and systems. Individual Hydra slides are available in the following formats. Hydra, Plain (whole mount)- Stained, well-relaxed specimen showing general structures. Hydra with Food (whole mount), Schneider's and fast green- Selected to show ingested food particles within the gastro vascular cavity. Hydra, General Structure (cross section), hematoxylin & -eosin- Shows the differentiated cells of the epidermis and gastro dermis separated by the noncellular mesoglea. Hydra, General Structure (longitudinal section), hematoxylin & -eosin- Demonstrates cellular structure and body plan. Hydra, Nematocysts (whole mount), giemsa stain- Demonstrates nematocysts, coiled and discharged. Hydra with Ovary (whole mount) Schneider's and fast green- Demonstrates adult hydra with ovaries. Hydra with Spermaries (whole mount) Schneider's and fast green- Hydra showing spermaries, the organs that produce spermatozoa. Hydra with Bud (longitudinal section) hematoxylin & -eosin- Shows the gastro vascular cavity as a continuous structure from parent to bud. Hydra with Bud (whole mount) Schneider's and fast green- Whole mount showing Hydra with bud, demonstrating asexual reproduction. Hydra, Plain & -Budding Specimens (whole mount) Schneider's and fast green- Composite slide showing plain adult hydra and hydra with bud side by side."
