Question

short answer sbi3u1 biodiversity ku /13 think /6 app /6 comm /10 q1. what is the main feature used to classify euglena as a plantlike protist? list four identifying features of paramecium ku /6 q2.a). gram positive and negative bacteria are different from each other comment. think /4 gram positive.

Explanation:

Q1: Euglena is classified as a plant - like protist mainly because it contains chloroplasts and can perform photosynthesis. Paramecium features include: it has a slipper - like shape, cilia for movement, a macronucleus and micronucleus, and a contractile vacuole for osmoregulation.
Q2.a: Gram - positive bacteria have a thick peptidoglycan layer in their cell wall and retain the crystal violet - iodine complex in the Gram staining process, appearing purple. Gram - negative bacteria have a thin peptidoglycan layer and an outer membrane, and they take up the counter - stain (safranin) and appear pink.

Answer:

Q1: Main feature of Euglena as plant - like protist: Presence of chloroplasts for photosynthesis. Four features of Paramecium: Slipper - like shape, cilia for movement, macronucleus and micronucleus, contractile vacuole for osmoregulation.
Q2.a: Gram - positive bacteria have a thick peptidoglycan layer, retain crystal violet - iodine complex (purple in Gram staining). Gram - negative bacteria have a thin peptidoglycan layer and outer membrane, take up safranin (pink in Gram staining).
