Flowering plants are plants that produce flowers which contain stamen and ovaries. After fertilization, the petals drop off, the ovary enlarges to become the fruit and the ovules become the seeds. There are fleshy and juicy fruits like tomatoes and durians as well as dry fruits like nuts and peas.
As we know, plants need space, nutrients and light to live. Seeds cannot grow well under the shade or overcrowded conditions. As plants have limited movement, it is necessary for them to disperse their seeds through other agents. Dispersing seeds and fruits increases the chances of survival for new plants as they are moved away from the parent plants. Thus, intraspecies competition becomes less and they will have the basic needs to grow healthy.
