(a. amoeba, e. euglena, v. volvox, p. parameci)i. food vacuo ii. oral groove iii. contractile vacuole iv. nucleus v. cilia vi. cell membra. __b. c. d. e. f. name the organismg. _____________4. match the letters pictured to the correct structures: i. (a. amoeba, e. euglena, v. volvox, p. parameci)i. colony ii. offspring iii. contractile vacuole iv. nucleus v. chloroplast vi. cell membranvii. eyespot viii. flagella

Explanation:

Step1: Identify organism

The organism has cilia, oral groove, and a characteristic oval shape with specialized vacuoles, which matches Paramecium (P.).

Step2: Match structure A

A points to the outer layer: Cell Membrane (VI)

Step3: Match structure B

B points to the dark, rounded internal structure: Nucleus (IV)

Step4: Match structure C

C points to the funnel-like indentation: Oral Groove (II)

Step5: Match structure D

D points to hair-like projections on the surface: Cilia (V)

Step6: Match structure E

E points to the star-shaped regulatory vacuole: Contractile Vacuole (III)

Step7: Match structure F

F points to the small sac for digestion: Food Vacuole (I)

Step8: Name the organism

Based on structures, it is Paramecium (P.).

Answer:

A. VI. Cell Membrane
B. IV. Nucleus
C. II. Oral Groove
D. V. Cilia
E. III. Contractile Vacuole
F. I. Food Vacuole
G. P. Paramecium
