Comparison of plant cell and animal cell
| Plant Cell | Animal Cell |
|---|---|
| Cell wall is present outside the plasma membrane. Generally regular in shape. | Cell wall is absent. Generally irregular in shape. |
| Plastids are present. | Plastids are absent except in Euglena. |
| A permanent and large vacuole is present. | Vacuoles are many, small and temporary. |
Two circles intersect at two points B and C. Through B, two line segments ABD and PBQ are drawn to intersect the circles at A, D and P, Q respectively (see Fig. 9.27). Prove that ∠ACP = ∠ QCD

ABCD is a trapezium in which AB || CD and AD = BC (see Fig. 8.14). Show that
(i) ∠A = ∠B
(ii) ∠C = ∠D
(iii) ∆ABC ≅ ∠∆BAD
(iv) diagonal AC = diagonal BD [Hint : Extend AB and draw a line through C parallel to DA intersecting AB produced at E.]

(ii) The kind of person he wants to be (appearance, ambition)
