Question

Even though the name protozoa means first animal, the larger protist group contains some organisms that appear plant like because they A. Have roots that anchor them in one place and cannot move to feed. B. Contain chlorophyll. C. Produce their own food using sunlight to carry out photosynthesis. D. Live in the soil while using nutrients like nitrogen and phosphorus to grow. A protozoan is a single cell. So, what makes a protozoan any different from any of the other individual cells found in a multicellular organism? A. The difference is that all of life's activities are carried out in the protozoan cell, which allows them to live independently or in colonies. B. The difference is that all protozoa have flagella that enable them to move to find food, whereas cells of multicellular organisms lack the ability to move independently. C. There is no real difference except that protozoa do not form parts of an animal's tissues. D. Protozoa have a nervous system and mouth. Some protozoa have specialized structures that carry out functions similar to those of a multicellular organism. Try and match the functions of animal bodies with structures within the plasma membrane of some protozoan organisms. Anus (or terminal region of large intestine) Stomach and small intestines Mouth Large intestine (and rectum) ___Cytopharynx ___Food vacuoles __Egestion vacuole ___Cytopyge

Answer 1

1.The correct answer is :B.contain chlorophyll.

Reason: Euglena is a plant like protist that contains chloroplasts containing chlorophyll.

2.A prootozoa is a single cell.So, what makes a potozoan different from any of the other individual cells found in a multicellular organism. The correct answer is: A.

Reason:Protists are unicellular but they have nucleus and membrane bound organelle in their cell and so can survive independently.

3.mouth------ cytopharynx

2.Stomach and small intestines -----Food vacuoles

4. Large intestine (and rectum)----Egestion vacuole

1.Anus or terminal region of large intestine ---- Cytopyge
