Given below is a diagrammatic sketch of a certain generalised cell.
(a) Name the parts numbered as I to 8.
(b) Is it a plant cell or an animal cell? Give two reasons in support of your answer.
(c) Give the functions of parts marked as 1, 6 and 8.

(a)1-Mitochondria 2-vacuole 3-starch granule 4-cytoplasm 5-nucleolus 6-nucleus 7-cell membrane 8-cell wall (b) plant cell because it has cell wall and a large vacuole (c) 1- synthesis of respiratory enzymes and produces cell's energy 6-regulates cell functions and contain chromosomes 8-give rigidity and shape to cell and provides protection

A car starts from rest and moves along y axis with a constant acceleration of 10 m/s2 for 10 seconds. If it continues with constant velocity, what distance it will cover in 24 second? OR The velocity-time graph of a particle of mass 50 g moving in a definite direction is shown in the following figure. Answer the questions based on this figure. (a) What is the velocity of the particle at point ‘A’? (b) Find the momentum of the particle at time t = 4 s. (c) What does the slope of a graph represent? (d) Calculate the distance travelled in 4 seconds
