Multiple Choice Questions
(a) It shows metamerism, and the number of segments varies from 100-120
(b) The first segment at the anterior end of the body is called as the ‘buccal segment’ or Peristomium
(c) The first segment is Prostomium
(d) The skin of earthworm is brown due to the presence of porphyrin
Show Answer & Explanation
Answer: (c) The first segment is Prostomium
Explanation:
1. Earthworm's first segment (peristomium) bears the mouth; the prostomium is a lobe above the mouth, not the first segment. The other statements are right.
Teacher's Note:
1. Prostomium is not a segment.
(a) Setae, muscles and hydrostatic skeleton
(b) Setae alone
(c) Muscles alone

Show Answer & Explanation
Answer: (d) Clitellum or Cingulum – 9th to 14th segment
Explanation:
1. The clitellum covers the 14th to 16th segments, not 9th to 14th, so (d) is the wrong match.
Teacher's Note:
1. Clitellum forms the cocoon.
(a) Chromophil cells
(b) Chloragogen cells
(c) Calciferous gland cells
(d) Albumen cells
Show Answer & Explanation

Teacher's Note:
1. Typhlosole means blind tube.
(a) Pheretima represents a closed type of blood vascular system
(b) Blood glands are present in 4th, 5th and 6th segments, they produce blood cells and haemoglobin dissolved in plasma

(d) In dorsal vessel blood flows in forward direction and is without valves
Show Answer & Explanation
Answer: (d) In dorsal vessel blood flows in forward direction and is without valves
Explanation:
1. Earthworm has a closed system, blood glands in segments 4, 5, 6 and four pairs of hearts in 7, 9, 12 and 13. The dorsal vessel has valves, so saying it has no valves is incorrect.
Teacher's Note:
1. Valves prevent backflow.
(a) 11 & 12
(b) 12 & 13
(c) 14 & 15
(d) 10 & 11
Show Answer & Explanation
Answer: (d) 10 & 11
Explanation:
1. Two pairs of testes lie in the 10th and 11th segments.
Teacher's Note:
1. Ovaries in the 13th.
(a) Female genital pore to spermathecae
(b) Male genital pores to spermathecae
(c) Spermathecae to cocoon
(d) Male genital pores to outside
Show Answer & Explanation
Answer: (b) Male genital pores to spermathecae
Explanation:
1. During copulation, sperms are exchanged from the male genital pores of each worm into the spermathecae of the other.
Teacher's Note:
1. Mutual exchange.
(a) Fertilization is external and cross fertilization
(b) There are two pairs of testes in 10th and 11th segments and one pair of ovaries attached at the intersegmental septum of 12th and 13th segment
(c) Accessory glands are present on the ventral surface of 17th and 19th segments
(d) Earthworm is unisexual
Show Answer & Explanation
Answer: (d) Earthworm is unisexual
Explanation:
1. Earthworm is hermaphrodite (monoecious), not unisexual; the other statements are correct.
Teacher's Note:
1. Cross fertilisation due to protandry.
(a) Burrowing
(b) Fertilisation
(c) Producing cocoons
(d) Locomotion
Show Answer & Explanation
Answer: (c) Producing cocoons
Explanation:
1. The clitellum secretes the cocoon in which eggs are laid, and also secretes albumin.
Teacher's Note:
1. Glandular band.
(a) Supra-oesophageal and dorsal vessel to ventral vessel
(b) Dorsal vessel to sub-oesophageal vessel
(c) Lateral oesophageal vessel to subneural vessel
(d) Dorsal vessel to subneural vessel
Show Answer & Explanation
Answer: (a) Supra-oesophageal and dorsal vessel to ventral vessel

(c) Presence of genital papillae
(d) None of these
Show Answer & Explanation
Answer: (c) Presence of genital papillae
Explanation:

Teacher's Note:
1. Papillae on 17th and 19th.
(a) Oesophagus
(b) Gizzard
(c) Stomach
(d) Intestine
Show Answer & Explanation
Answer: (b) Gizzard
Explanation:
1. The gizzard occupies the 8th and 9th segments; the oesophagus is in the 6th and 7th.
Teacher's Note:
1. Gizzard grinds soil.
(a) Pharyngeal nephridia
(b) Septal nephridia
(c) Integumentary nephridia
(d) Integumentary and pharyngeal nephridia
Show Answer & Explanation
Answer: (c) Integumentary nephridia
Explanation:
1. Integumentary nephridia open directly to the outside (exonephric), whereas septal and pharyngeal nephridia open into the gut (enteronephric).
Teacher's Note:
1. Exo- means outside.
(a) Ammonotelic
(b) Ureotelic
(c) Uricotelic
(d) Ureotelic and ammonotelic
Show Answer & Explanation
Answer: (d) Ureotelic and ammonotelic
Explanation:
1. Earthworm excretes mainly ammonia when water is plentiful and urea when water is scarce, so it is both ammonotelic and ureotelic.
Teacher's Note:
1. Adapts to water.
(a) 3, 4, 5
(b) 4, 5, 6
(c) 5, 6, 7
(d) 6, 7, 8

Answer: (b) 4, 5, 6
Explanation:
1. Pharyngeal nephridia are tufts of nephridia in the 4th, 5th and 6th segments.
Teacher's Note:
1. Enteronephric.
(a) Muscular Gizzard – 8-9th segments
(b) Oesophagus – 9-14th segments
(c) Intestine – 15th segment onward
(d) Typhlosole – 27-95th segment
Show Answer & Explanation
Answer: (b) Oesophagus – 9-14th segments
Explanation:
1. In Pheretima the oesophagus is in segments 6-7 and the stomach in 9-14, so the 9-14th segment oesophagus match is incorrect.
Teacher's Note:
1. Gizzard 8-9, intestine from 15th.
