Plants need the insects to carry the pollen to seeds. Since the neighbor sprayed insecticide because the Japanese beetles attacked their rose garden‚ there are no insects there to carry the pollen. Fruits won’t form unless the flowers are pollinated. Insects are considered pollinators for plants‚ without them the pollen would not go around. Pollination is needed to produce new seeds and create a wide variety of plants. 4. Table 16.7 Uses of Seeds Plants: Angiosperms and Gymnosperms Uses of

bananas and nectarines combined. The seeds can vary from ¾ to 1 ½ inches in length and there can be anywhere from 100 to 500 seeds in a single fruit. A milky white latex rubber surrounds all of the seeds. Jackfruit only come in only two varieties but the names very from area to area the basic types are "Khuja" which is green‚ hard and smooth‚ with juicy pulp and small seeds and "Ghila" which is rough‚ soft‚ has thin pulp‚ isn’t very juicy‚ and has large seeds. This fruit has very picky growing conditions

sporangium. Nature had to evolve protection for the gametophytes‚ and it came up with an embryo inside the ovary‚ carpel‚ or pistil. The seed also evolved a hardened protective covering to aid in reproduction. Seed became carried in fruits‚ which were eaten by animals that dispersed the seeds and aided in reproduction. In addition‚ seed dormancy allows the seed to remain latent for extended periods of time. Lastly‚ the evolution of internal fertilization using the pollen tube and endosperm helped

INTRODUCTION The oil seed crop Arachis hypogea L. (groundnut/peanut) belongs to family the leguminosae and sub family Papillionacea. The seed containing 50% oil and 25 to 30% proteins can be used as meal for food and feed (Ahmad and Rahim‚ 2007). In Pakistan‚ about 85% of total groundnut is grown in Potowar tract of Punjab‚ 13% in

Several studies show that music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant

and wheat seeds affect the plants growth rate and competition. The competition occurs when resources are limited to the plants. The two types of competitions that occur are interspecific and intraspecific. Interspecific is a competition between two different species and intraspecific is a competition between the plants own species. This experiment was conducted by taking 6 pots containing soil and placing certain amount of seeds‚ radish or/and wheat seeds‚ in each pot. A total of 384 seeds were needed
