Fertilizers are essential in plant growth due to the lack of some nutrients in the soil. They contain three distinct categories which are the primary nutrients‚ secondary nutrients and metals. (hazri). In order for a plant to develop growth‚ the basic needs of carbon (C)‚ hydrogen (H)‚ and oxygen (O) are required which are available in the air and water. Also‚ a boost of macronutrients are also essential for plant growth which are obtainable from chemical fertilizers mainly nitrogen (N)‚ phosphate

Parts of plants Each part of a plant has a very important function. All plants produce flowers for the same reason: to make seeds so another plant can grow. Leaves: These are the parts of the plant where food is made by photosynthesis. Leaves take in carbon dioxide from the air‚ water from the soil‚ and energy from the sunlight. During photosynthesis‚ the leaves use light energy to change carbon dioxide and water into food. (sugar) Flowers: These are the reproductive parts of

CHAPTER 36 PLANT CELLS The first barrier to form between daughter cells is the middle lamella. Daughter cells expand to their final size and make polysaccharides for a primary wall. After expansion stops waterproofing materials are added for a secondary wall. Water and dissolved materials move from cell to cell by way of pit pairs. A pit is a thin spot in the primary wall where the secondary wall is absent or separated from the primary wall by a space. Strands of cytoplasm called

The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period
