Plants+influences.

Many things influence a plant's growth, but mostly a plant is influenced by sun and water. Auxins promote cell growth and fruit development. Ethylene promotes leaf abicission and fruit ripening. Abscisic acid imposes seed dormancy and winter dormancy. Hormones are plant development and growth. Tropisms are growth or movement of plants toward or away from something in environment. Negative Tropism is the movement away from stimulus. Positive Topism is the movement toward enviromental stimulus. Phototropism is the response to light to ensure that they get plently of light. Geotropism plant growth response to gravity. Thigmotropism is the growth in response to touch. Parenchyma is the abundant tissue type. It consists of living cells, makes bulk of plant. Collenchyma helps strengthen the plant. Schlerenchyma are wallsthat are made up of dead cells. Xylem moves water. Phloem moves sugar and other colutes. The cuticle is waxy protective layer. Meristematic is the ability for cells to divide. Epidermis carry photosynthesis. Cambium is the layer of the meristem tissue in stems and roots of the plant that produce all growth in a diameter, including new xylem and phloem cells. Fibrous is close to the soil surface. Taproot is tapering root with slender, short, side branches. Root hairs penetrate spaces between soil particles. Fertilizers can effect plants because it gives the plant nutrients to grow so it makes the plant grow faster and healthier.
