what is the answer? a,b,c Some animals seem to be more similar to plants than animals. This is especially true for sessile ones—those that just sit in one place for the majority of their lives. For example, the giant clam Tridacna sits in one place all the time, sunning itself and essentially farming photosynthetic algal symbionts from which it draws its nutrients. Sea anemones and corals just sit in the same place their whole lives, catching organic material that falls from above. How is that any different from a pitcher plant? Answer the following questions to reach a conclusion: a. Why do we still refer to a giant clam as a metazoan? - Type answer here.b. How is a pitcher plant similar to a sea anemone? - Type answer here.c. How is it different? - Type answer here.

Plants are mainly multicellular organisms, predominantly photosynthetic eukaryotes of the kingdom Plantae. Plants are termed as autotrophs and are the primary producers in almost all of the ecosystems on the earth. Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Following are the characteristics of animals: All animals are made up of cells that do not have cell walls. All animals are multicellular organisms. Most animals reproduce sexually. Some are capable of asexual reproduction by fragmentation, budding, or parthenogenesis. All animals are capable of self-propelled motion at some point in their lives. All animals are heterotrophic and must consume other organisms for energy. All animals are capable of responding to external stimuli through the use of nerve, muscle, or contractile tissue.Why do we still refer to a giant clam as a metazoan? All organisms belonging to kingdom Animalia are called metazoans (any animal that undergoes development from an embryo stage with three tissue layers, namely the ectoderm, mesoderm, and endoderm). The giant clams are the members of the clam genus Tridacna that are the largest living bivalve molluscs (belonging to phylum Mollusca). The giant clams are considered as metazoans as they display most of the characteristics (mentioned above) shown by organisms in kingdom Animalia. How is a pitcher plant similar to sea anemone? Sea anemones Sea anemones are the marine, predatory animals of the order Actiniaria. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra. A typical sea anemone is a single polyp attached to a hard surface by its base, but some species live in soft sediment and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. The tentacles are armed with cnidocytes (stinging cells), cells that are both defensive and used to capture prey. Pitcher plants Pitcher plants are several different carnivorous plants which have modified leaves known as pitfall traps which are a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. Foraging, flying or crawling insects such as flies are attracted to a cavity formed by the cupped leaf, often by visual lures such as anthocyanin pigments, and nectar bribes. The rim of the pitcher (peristome) is slippery when moistened by condensation or nectar, causing insects to fall into the trap. They drown the insect, whose body is gradually dissolved. This may occur by bacterial action (the bacteria being washed into the pitcher by rainfall), or by enzymes secreted by the plant itself. Pitcher plant and sea anemone are both sessile (attached to a surface), heterotrophic organisms and use various predatory mechanisms to catch prey. How is it different? Sea anemone and pitcher plant differ as follows: Sea anemone belongs to kingdom Animalia (is an animal) and pitcher plant belongs to kingdom Plantae (is a plant). Sea anemone is exclusively found in marine habitat (sea water and oceans), whereas pitcher plant is terrestrial growing on soil surface.
