Q5. Assertion: animals store food reserves as glycogen or fat. Reason: animal cells lack cell walls. Are both true, and does the reason explain the assertion?
Both are true (NCERT page 19), but the reason does not explain the assertion.
Q6. Which of these is not a feature of Kingdom Animalia: (a) multicellular, (b) cell wall of chitin, (c) holozoic nutrition, (d) reserves as glycogen?
(b). Animal cells lack cell walls; chitin walls belong to fungi.
Q7. What does NCERT say about the growth of animals?
They follow a definite growth pattern and grow into adults that have a definite shape and size (page 19).
Q8. Where in NCERT are the salient features of the animal phyla described?
In Chapter 4 (NCERT page 19).
Q9. Which column of NCERT Table 2.1 lists both holozoic and saprophytic nutrition?
Animalia (NCERT page 11).
Q10. Do all animals move from place to place?
No: NCERT says most of them are capable of locomotion (page 19).
Q11. How do Animalia and Plantae differ in cell wall and mode of nutrition (NCERT Table 2.1)?
Animalia: no cell wall, heterotrophic (holozoic/saprophytic etc.). Plantae: cellulose cell wall, autotrophic (photosynthetic) (NCERT Table 2.1, page 11).
Q12. A single-celled eukaryote has no cell wall and ingests food. Is it an animal?
No. Animals are multicellular (NCERT page 19). A protozoan such as Amoeba fits the description, but these few traits alone are not enough to identify its precise protist group.
