He described about this in his book “Micrographic”.  Cell is a Latin word which means ‘a little room’. The word cell was derived from a Greek word “Cellulae” which means small room. First living cell was discovered by A.V. Leeuwenhoek with the improved microscope in pond water. Q. What are Living Organisms made up of? Answer: All living organisms that we observe around us are made up of cells. Q. Who gave the cell theory? What does it state? Which organism is an exception of cell theory?

CBSE PHYSICS: IX Motion And Rest Formative Check Points For FA-01.. : Q. Define terms (i) One radian (ii)  Angular displacement (iii) Angular velocity Answer: One radian is defined as the angle subtended at the centre of the circle by an arc equal in length to its radius. Angular displacement : In a circular motion, the angular displacement of a body is the angle subtended by the body at the centre in a given interval of time. It is represented by the symbol  q  (theta).                                Angular velocity : The angular displacement per unit time is called the angular velocity. it is represented by the symbol  w (omega). Angular velocity  w  =  q /t In figure, the arc AB of the circle has length  l   and subtends an angle  q  at the centre C Click on given link to read full post:   Check Points For FA-01
