in planaria
Nephridia are excretory organs found in some invertebrates that eliminate metabolic waste and excess fluids from the body through openings called nephridiopores. These structures help maintain proper osmoregulation and remove nitrogenous waste products from the body.
The gametophytes of gymnosperms live inside reproductive structures called cones. Gametophyte is the immediate result of fertilization in mosses.
Tiny structures found in the cytoplasm that carry out various functions are called organelles. These organelles include structures like mitochondria, ribosomes, and the endoplasmic reticulum, each responsible for specific cellular tasks such as energy production, protein synthesis, and lipid metabolism.
The reproductive structures of bryophytes are called gametangia. These structures produce the gametes (sperm and egg) necessary for sexual reproduction in bryophytes. Gametangia are typically found at the tips of the gametophyte plant.
You would find cells with hair-like structures on the surface of the skin called cilia or on the lining of the respiratory tract. These structures play a role in moving substances along the surface of the cell or organ they are found in.
protonephridia, metanephridia... Gills?
The flame-cell system in planarians consist of specialized cells called flame cells that are part of the excretory system. Flame cells have distinctive cilia that beat rapidly, creating a flickering appearance like a flame. These cells help regulate the osmotic balance and remove waste from the body by actively pumping fluids through the excretory system.
Solenocytes are excretory cells found in the protonephridia of some invertebrates, while flame cells are specialized excretory cells found in the excretory system of flatworms. Solenocytes have cilia that create a flow of fluid, whereas flame cells have a tuft of cilia that beat to create the flow of fluid. Both types of cells are involved in excretion and osmoregulation in their respective organisms.
chromosomes
They are called rhizoids.
the excretory system
Nephridia are excretory organs found in some invertebrates that eliminate metabolic waste and excess fluids from the body through openings called nephridiopores. These structures help maintain proper osmoregulation and remove nitrogenous waste products from the body.
An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.
The cells found in the excretory system are: one pore cell, one duct cell, one canal cell and a pair of gland cells.
Frogs have one excretory opening, known as the cloaca, which is used for both waste elimination and reproduction.
chromosomes
The excretory system is at the en of the large intestine. The waste from your body is extracted there... as in like urine and solid waste.
