Question

An individual mixotroph loses its plastids, yet continues to survive. Which of the following most likely accounts for its continued survival? It relies on photosystems that float freely in its cytosol. It must have gained extra mitochondria when it lost its plastids. It engulfs organic material by phagocytosis or by absorption. It has an endospore. It has multiple alveoli. Which factor most likely caused animals and plants in India to differ greatly from species in nearby Southeast Asia? The species became separated by convergent evolution. The climates of the two regions are similar. India is in the process of separating from the rest of Asia. India was a separate continent until 45 million years ago. In a sample of pond water, a new organism is identified with the following characteristics It consists of 70 cells surrounded by rigid cell walls that join the cells together Inside each of these identical cells are mitochondria and chloroplasts. Such an organism would most likely be classified as a colonial photosynthetic eukaryote. fungal photosynthetic eukaryote colonial photosynthetic prokaryote. multicellular photosynthetic prokaryote colonial eukaryotic fungus. Which of the following is the most likely sequence of events, from earliest to most recent, in the evolution of sponges (organisms with many cells that lave different functions)? single-celled eukaryote single-celled prokaryote multicellular eukaryote colonial eukaryote 2, 1, 4, 3 2, 1, 3, 4 1, 2, 3, 4 1, 2, 4, 3 The chloroplasts of land plants are thought to have been derived according to which evolutionary sequence? cyanobacteria rightarrow green algae rightarrow land plants cyanobacteria rightarrow green algae rightarrow fungi rightarrow land plants red algae rightarrow brown algae rightarrow green algae rightarrow land plants cyanobacteria rightarrow red algae rightarrow green algae rightarrow land plants Green algae differ from land plants in that some green algae.

Explanation / Answer

24. The correct answer is option C - cell engulfs the solid particle and form phagosome. Phagocytosis is the process of removal of pathogens and cell debris.

25.  The correct answer is option D - India was sepearate continent until 45 million years ago. Under the condiotions of primitive earth, life is formed and it leads to simple forms changed into complex.

26. The correct answer is option A - Eukaryote cells have rigid cell walls and definite nucleus than prokaryote. Rigid cell walls contain mitochondria and chloroplasts.

27. The correct answer is option A - Prokaryotes dont have a definite nucleus and 70S ribosomes are present in the cells. Eukaryotes have define nucleus with 80S ribosomes.

28. The correct answer is option A - Cyanobacteria also called as Blue green algae comes under prokaryotes, followed by green algae comes under Eukaryotes and land plants also under eukaryotes.
