A unicellular animal P having no fixed shape ingests a food particle by forming temporary finger-like projections Q. The food particle is engulfed with a little surrounding water to form a temporary stomach R inside it. The chemicals S from surrounding cytoplasm enter into R and break down food into small and soluble molecules by chemical reactions. The digested food is absorbed directly into cytoplasm by the process T. The undigested food is thrown out of the body by the rupture of a cell organelle U in a process called V.
(a) Name the unicellular animal P.
(b) What are (i) Q, and (ii) R?
(c) Name (i) chemical S, and (ii) process T.
(d) Name (i) organelle U, and (ii) process V.
