What is plant in plant biology?
Plants are the eukaryotes that comprise the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Plantae), any multicellular eukaryotic life-form characterized by (1) photosynthetic nutrition (a characteristic possessed by all plants except some parasitic plants and underground orchids), in which chemical energy is produced from water, minerals, and carbon dioxide with the aid of pigments and the .The plant kingdom consists of multicellular eukaryotic life-forms (see eukaryote) with six fundamental characteristics: photosynthesis as the almost exclusive mode of nutrition, essentially unlimited growth at meristems, cells that contain cellulose in their walls and are therefore somewhat rigid, the absence of organs .Plantae, comprising multicellular organisms that typically produce their own food from inorganic matter by the process of photosynthesis and that have more or less rigid cell walls containing cellulose, including vascular plants, mosses, liverworts, and hornworts: some classification schemes .Plants are the eukaryotes that comprise the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll.Chlorophyll is found in the chloroplasts of a plant’s cells, which are small structures. Answer: A chloroplast is a type of plastid (a saclike organelle with a double membrane) that is responsible for photosynthesis, or the conversion of solar energy into chemical energy for growth.
What is a stoma vs stomata?
A stoma is a pore or aperture surrounded by two guard cells that allow gas exchange. Stomata is the plural term for stoma. Stomata allow for gas exchange to occur, mainly carbon dioxide to enter the plant to make food molecules such as glucose and for oxygen to be released by the plant. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores — called stomata — to take in carbon dioxide and release oxygen. Stomata are tiny, microscopic and critical for photosynthesis. Thousands of them dot on the surface of the plants.Cut flower foliage, and to a lesser extent flower petals and stems, contain microscopic pores called stomata. Functioning stomata are made of two guard cells that permit the stomate (pore) to open and close in response to changing environmental conditions.Excretion of gaseous waste in plants takes place through stomatal pores on leaves.
Is a stoma for urine?
A urostomy is a type of ostomy surgery that creates an opening (stoma) in your abdomen for urine (pee). This opening allows urine to leave your body in a different way (urinary diversion). A surgeon attaches the stoma to a place in your urinary tract to let urine leave your body. Urostomy pouches are special bags that are used to collect urine after some types of bladder surgery. Instead of going to your bladder, urine will go outside of your abdomen into the urostomy pouch. The surgery to do this is called a urostomy. Part of the intestine is used to create a channel for the urine to drain.
