Why plants need nutrients?
- Plants already receive non-mineral nutrients from the air Plants already receive non-mineral nutrients from the air and water. (Hydrogen, Oxygen, and Carbon)and water. (Hydrogen, Oxygen, and Carbon)
- 13 out of 16 nutrients are mineral nutrients.13 out of 16 nutrients are mineral nutrients.
- These 13 nutrients come from soil, which are later These 13 nutrients come from soil, which are later dissolved in water and the roots of the plant absorbs these dissolved in water and the roots of the plant absorbs these nutrients.nutrients.
- Nutrients from the soil may not always be enough, so Nutrients from the soil may not always be enough, so farmers use fertilizers to make up for the loss. farmers use fertilizers to make up for the loss.
- The nutrients needed are broken into two categories… The nutrients needed are broken into two categories…

• Vascular plantsVascular plants: have two network tubes in the plant : have two network tubes in the plant (roots, leaves, stem). One of the network tubes transports (roots, leaves, stem). One of the network tubes transports food made in the leaves to the plant and the other food made in the leaves to the plant and the other transports water. This water and food is used to reproduce. transports water. This water and food is used to reproduce. Flowering plants are one kind of vascular plant. Nutrients Flowering plants are one kind of vascular plant. Nutrients and water enter the plant through the roots. There are and water enter the plant through the roots. There are water tubes in the roots that carry the water to the water water tubes in the roots that carry the water to the water tubes that are in the stem. Then the water tubes in the tubes that are in the stem. Then the water tubes in the stem carry the water to the water tubes that are in the stem carry the water to the water tubes that are in the leaves. Some of the water gets evaporated during leaves. Some of the water gets evaporated during transpiration. The food tubes transport food made in the transpiration. The food tubes transport food made in the leaves to the food tubes in the stem and roots. Some of leaves to the food tubes in the stem and roots. Some of the food tubes run from the leaves to the rootsthe food tubes run from the leaves to the roots..
Roles of the tissues :• Xylem: transports water and Xylem: transports water and
soluble mineral nutrients from soluble mineral nutrients from the roots all the way through the the roots all the way through the plant. It is used to replace the plant. It is used to replace the water lost during water lost during transplantation. The sap in transplantation. The sap in xylem is made of mainly water xylem is made of mainly water and inorganic ions, but it can and inorganic ions, but it can have organic chemicals too.have organic chemicals too.
• Phloem: the living tissue that Phloem: the living tissue that carries organic nutrients that are carries organic nutrients that are called photosynthate, called photosynthate, particularly sucrose (a sugar) to particularly sucrose (a sugar) to all of the part of the plant that all of the part of the plant that need it.need it.
• Meristem: the tissue that is Meristem: the tissue that is in all plants that has in all plants that has undifferentiated cells undifferentiated cells (meristematic cells) that is (meristematic cells) that is found is the places where found is the places where growth takes place in the growth takes place in the plant. These cells cannot plant. These cells cannot divide or produce cells of a divide or produce cells of a different type so they are different type so they are responsible for the basic responsible for the basic plant structure and plant structure and initiation of new organs.initiation of new organs.
• Vascular Cambium: the Vascular Cambium: the source of secondary xylem source of secondary xylem and secondary phloem. and secondary phloem. This is located between This is located between the tissues in the stem and the tissues in the stem and root. Consists of two types root. Consists of two types of cells: Fusiform initials of cells: Fusiform initials and Ray initials.and Ray initials.
• Cork Cambium: is a tissue Cork Cambium: is a tissue that is responsible for that is responsible for secondary growth that secondary growth that replaces the epidermis in replaces the epidermis in the roots and stems.the roots and stems.
Mesophyll: the tissue Mesophyll: the tissue between the lower and between the lower and upper epidermis of leaf upper epidermis of leaf blades made of blades made of parenchyma-like cells.parenchyma-like cells.
• Stele: the central part of Stele: the central part of the root or stem the root or stem containing vascular containing vascular tissue and sometimes a tissue and sometimes a pith. This transports pith. This transports water and nutrients water and nutrients throughout the plantthroughout the plant
nutrients in part 1 are important to each
plant and explanations:
• Corn: Most important- nitrogen mostly needed Corn: Most important- nitrogen mostly needed for plant growth. molybdenum is the second for plant growth. molybdenum is the second most important. Mo fixes the atmosphere of most important. Mo fixes the atmosphere of nitrogen.. without it, there is little nitrogen nitrogen.. without it, there is little nitrogen production which may cause a decrease in production which may cause a decrease in plant growth. these two nutrients work hand in plant growth. these two nutrients work hand in hand for successful plant growth. the rest of hand for successful plant growth. the rest of the nutrients follow the patterns to keep the the nutrients follow the patterns to keep the plant steady in growth while nitrogen and plant steady in growth while nitrogen and molybdenum are used mostly.molybdenum are used mostly.
• Pepper: manganses is Pepper: manganses is an an important nutrient for important nutrient for rapid growth in rapid growth in peppers.. although it peppers.. although it is beneficial, too much is beneficial, too much of manganese can of manganese can cause mangases cause mangases toxicity. the leaves toxicity. the leaves begin to turn yellow begin to turn yellow and causes and causes defoliation. defoliation.
• Onion: sulfur is vital in Onion: sulfur is vital in successful plant successful plant growth. it becomes as growth. it becomes as a protein for onions a protein for onions and aids in rapid and aids in rapid growth. because of the growth. because of the mass of sulfur, that is mass of sulfur, that is why people cry when why people cry when cutting onions. cells cutting onions. cells release enzymes which release enzymes which break down sulfur into break down sulfur into sulfenic acids which sulfenic acids which irritate the eye. irritate the eye.
Discussion
• First nutrients inter the plants and move up First nutrients inter the plants and move up the xylem by mass flow, this doesn’t mean the xylem by mass flow, this doesn’t mean that all the nutrients will get to where they are that all the nutrients will get to where they are needed. They must be transported from older needed. They must be transported from older leaves, shoots, fruits, and other parts using leaves, shoots, fruits, and other parts using the phloem.the phloem.
