Why seed plants are most successful?

The class X students of a secondary school in Krishinagar have been allotted a rectangular plot of land for their gardening activity. Saplings of Gulmohar are planted on the boundary at a distance of 1m from each other. There is a triangular grass lawn in the plot as shown in the figure. The student are to sow seeds of flowering plants on the remaining area of the plot. Taking A as origin, find the coordinates of the vertices of the triangle.

Also calculate the areas of the triangles in these cases. What do you observe ?

These questions consist of two statement each, printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses. A. If both Assertion and Reason are true and Reason is a correct explanation of the Assertion. B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion. C. If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion: The fungi are widespread in distribution and they even live on inside other plants and animals. Reason. Fungi are able to grow anywhere on land, water or other organisms because they have a variety of pigments including chlorophyll, carotenoids, fucoxanthin and phycoerythrin.

You have heard about serveral insectivorous plants that feed on insects. Nepenthes or the pitches plant is one such example. Which usually grows in shallow water or in marsh lands. What part of the plant os modified into a 'pitcher'? How does this modification help the plant for food even though it can photosynthesize like any other green plant?

For an experiment in Botany,two different plants, plant A nad plant B were grown under similar laboratory conditions.Their heights were measured at the end of each week for 3 weeks.The results are shown by the following graph. During which week did Plant A grow most?
