How do amoebas obtain food?
When an amoeba wants to eat a food particle, it extends a long, variably shaped structure around the item and engulfs it whole. These long structures are called pseudopodia, and amoeba can make and adjust them as necessary to move or capture food.

where are dorsal and ventral blood vessels found in earthworms?
The top-side of an animal is called the dorsal surface The bottom-side of an animal is called the ventral surface
How do paramecium obtain food?
To gather its food, the paramecium uses its cilia to sweep up food along with some water into the cell mouth after it falls into the oral groove. The food goes through the cell mouth into the gullet.

what does a capillary do?
A capillary is a small blood vessel that allows blood that is rich in oxygen and nutrients to flow from the arteries into the veins. A capillary is a small vessel that is characterised by a thin wall that allows blood to easily pass through.
What is a food vacuole?
A food vacuole is a membrane-bound organelle found in some unicellular eukaryotic cells. The vacuole digests food which has been taken into the cell by a process known as phagocytosis.
What are cnidocysts?
Cnidocytes are prey-capture and defensive cellsunique to animals of the phylum Cnidaria.
Description of cyclosis
Cyclosis is the circulation or streaming of the cytoplasm within some living cells. In plant cells, chloroplasts may be moved around with the stream, possibly to a position of optimum light absorption for photosynthesis.

Why do we say jellyfish and hydra have a 2 way digestive system?
Food goes in and out of the same place.
How Do Jellyfish Get Food?
Preys are brought (by tentacles, if they have any) into the cavity, called coelenteron, where it is digested. Jellyfishes have an incomplete digestive system, meaning that the same orifice is used for both food intake and waste expulsion.
Describe a grasshoppers heart.
Putting it simplistically, a large tube functions as a heart and squishes the hemolymph (a blood and tissue fluid combo) around, washing over the internal organs.
What do grasshoppers have so they can do chemical digestion?
Salivary glands (occur in buccal cavity) chemically digest the carbohydrates in the grasses and similar foods they eat.
Where does digestion occur in jellyfish or hydra?
The gastrovascular cavity.
what is hemolymph?

Where is the typhlosole and what purpose does it serve?
it is located inside the small intestine and On an earthworm, the function of the typhlosole is to improve the efficiency with which the intestines absorb nutrients.
what is meant by an open circulatory system?
pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
What purpose do nematocysts serve?
stinging nematocysts function primarily for the capture of prey, and secondarily as a defense mechanism. There are many types of nematocysts, such as those that function to inject toxins to immobilize prey, and those which serve to entangle and hold onto the intended meal by wrapping around it.
