Reproduction in Plants Class 7 - Worksheet/Questions This worksheet is for Class 7 Science and covers the topic of Plant Reproduction. This is an important Science topic that will also serve as a foundation for plant biology in future classes. As a result, students must have a thorough understanding of the subject. 1. Fill in the blanks: _________ propagation is the process of producing new individuals from the vegetative component of a parent. The transport of pollen grains from the anther to the stigma of the same or another flower of the same species is known as ___________. Seed dispersal takes place through __________, __________, and __________ The merging of male and female gametes occurs during ____________. 2. State True/False: Pollination is the process of transporting seeds to distant locations. The fruit is formed by successive divisions of the zygote. Yeast multiply in two ways: asexually and sexually. Pollen grains are a flower’s male gametes. Ginger has nodes and interno

What are the characteristics of matter?   Everything around us is made up of small particles known as matter, as we all know. These particles have a few distinguishing characteristics that we will discuss. These characteristics can be divided into two categories: physical and chemical . We recommend going over the differences between physical and chemical changes first for a straightforward separation between the two groups. You can brush up on your concept by visiting our blog . The physical and chemical properties of matter are now dependent on how the properties of the substance change, in the same way that physical and chemical changes are dependent on how the properties of the substance change. It does not need to undergo any changes or transformations in order to identify the physical properties of matter. Chemical qualities of matter, on the other hand, necessitate the transformation of substances into other forms of matter. Physical Properties of Matter Matter's physical qu

Class 7 Science Motion and Time What is motion? The motion of an object is defined as the change in its position with respect to time. When the position of an object does not change with respect to time, the object is said to be at rest or stationary.  What is the difference between uniform and non-uniform motion? The differences are- Uniform motion It is a type of motion wherein the object moves in a straight line. Its velocity remains unchanged along that straight line, irrespective of the time duration. It occupies equal distances at equal time intervals. Uniform motion has zero acceleration. The uniform motion and the actual speed of the object are identical. The equal distance at an equal interval of time. The distance to time graph is a straight line. Non-uniform motion Contrary to Uniform motion, Non-Uniform Motion is a type of motion wherein the object moves at different speeds and does not cover the same distance at equal time intervals, irrespective of the duration of the t
