Question 2

It is a unicellular ciliate protozoa with a slipper-like shape

Answer 2

Paramecium

Question 3

Length of Paramecium

Answer 3

50 to 350 micrometers

Question 4

Where do paramecia live

Answer 4

Freshwater ponds, ditches, those having abundant decaying organic matter

Question 5

Parts of a paramecium

Answer 5

Pellicle
Cytoplasm
Oral groove (vestibulum)
Anal pore (cytoproct)
Contractile vacuole
Radiating canals
Trichocysts
Cytopharynx
Food vacuoles
Macronucleus
Micronucleos
Cilia

Question 6

Part of the paramecium that supports the cell membrane and give the paramecium its shape

Answer 6

Pellicle

Question 7

Jelly-like substance that is located within the pellicle, responsible for cell shape, transport, and storage

Answer 7

Cytoplasm

Question 8

2 types of cytoplasm

Answer 8

Endoplasm
Ectoplasm

Question 9

A large oblique shallow depression that guide food particles into the pharynx

Answer 9

Oral groove

Question 10

Also called cell mouth, where the particles enter into the cell

Answer 10

Cytostome

Question 11

Lies on the ventral surface behind the cytostome. It is an exterior opening where undigested food waste, water, or gas are expelled

Answer 11

Anal pore

Question 12

These structures play a major role in osmoregulation and excretion

They have the anterior and the posterior region

They work alternately

Answer 12

Contractile vacuoles

Question 13

Paths to the contractile vacuoles

Collects water from the surrounding cytoplasm

Answer 13

Radiating canals

Question 14

Hair-like structures and a type of extrusome used for defense mechanisms and providing stability during feeding, and appear as thread-shaped filaments

Answer 14

Trichocysts

Question 15

Primary site for intake of food particles

Answer 15

Cytopharynx

Question 16

Digests food with the help of enzymes

Answer 16

Food vacuoles

Question 17

Center of all metabolic activities of the paramecium

Answer 17

Macronucleus

Question 18

Controls the reproductive abilities of the paramecium

Answer 18

Micronucleos

Question 19

Small hair-like projections used for locomotion, capturing food particles, and sensing the environment

Answer 19

Cilia

Question 20

What is the ciliary movement of paramecia

Answer 20

Wave-like manner
Spiral trajectory

Paramecium moves in a straight line, rotating about in its longitudinal axis in a counterclockwise direction

Question 21

How many cycles per second does the paramecium’s spiral movement revolve

Answer 21

1 cycle per second

Question 22

The ideal modern organism for studying biological processes and cellular structure

Answer 22

Paramecium

Question 23

2 ways by which paramecia reproduce

Answer 23

Asexual reproduction (binary fission)
Sexual reproduction (conjugation)

Question 24

Regulated cell functions such as respiration, protein synthesis, digestion

Answer 24

Macronucleus

Question 25

Where is macronucleus located

Answer 25

In the middle dorsal part of the body opposite to the cytopharynx

Question 26

Storage site for generic material.
Gives rise to macronucleus.
Involved in sexual reproduction

Answer 26

Micronucleos

Question 27

Guides food particles into the pharynx (gullet)

Answer 27

Oral groove
