Bile is synthesized by hepatocytes of the liver and stored and concentrated in the gall bladder. It contains bile salts (sodium glycocholate and taurocholate) that emulsify fats, aiding lipase action. Bile also contains bile pigments (bilirubin, biliverdin) from hemoglobin breakdown. Pancreas secretes pancreatic juice with digestive enzymes. Gall bladder only stores bile, doesn't produce it.
Explanation:
Amoeba, a protozoan, moves and captures food using temporary, foot-like extensions of its cytoplasm called pseudopodia (false feet). This type of movement is called amoeboid movement and is driven by the assembly and disassembly of microfilaments (actin) in the cytoskeleton. Cilia and flagella are hair-like structures used by other protozoans like Paramecium and Euglena.
Explanation:
Cuscuta (dodder) is a total stem parasite that wraps around the host plant and absorbs nutrients through haustoria. It lacks chlorophyll and leaves. Mimosa is sensitive plant, Nepenthes is insectivorous, Aloe vera is a succulent. Parasitic plants derive some or all of their nutrition from other living plants. Cuscuta is economically important as a weed.
