NUTRIENTS & WATER 4 YOU AND ME

Transpiration is water vapor leaving the plant through cells called stomata. This may occur in leaves, roots, flowers, and stems. Transpiration happens when stomata cells are opened. This process is necessary in order to let in carbon dioxide from the air to use in photosynthesis. Transpiration can cool off the plant, change the osmotic pressure of the cells, and make mass flow of nutrients and water from roots to shoots possible. Turgor pressure is caused by the osmotic flow of water from an area of low solute concentration outside of the cell to a higher solute concentration in the vacuole. This pressure pushes the plasma membrane against the cell wall of the plant. The vascular tissue transports water and nutrients through out the plant,There are two main tissues that carry out the functions of the vascular tissue; the xylem and the phloem. There are two meristems within the vascular tissue, the vascular cambium and the cork cambium.

Xylem is a type of tissue within the vascular tissue of a plant. It transports water from the roots through the rest of the plant. It also replaces water that was lost from photosynthesis and transpiration. Xylem is made up of two cell types called tracheids and vessel elements. These cells are long and the vessel elements are connected together into tubes called vessels. Stomata are pores in leaves and stems epidermis that are used for gas exchange. Guard cells are what protect the stomata...exactly like what a guard does. Guard cells control the size of the opening in the stomata. Oxygen and carbon dioxide enter the plant through stomata. These are used in photosynthesis and cellular respiration as well. At the same time, oxygen is leaving the plant, along with water vapor. The guard cells are wrapped around the stoma, which makes a circular shape around the stoma.

 

Soil & Plant Growth:

not enough nutrients, so plant growth is not well. A high amount of nutrients is needed, and if this is successful, the plant will thrive. Clay and sand negatively affect draining of plants therefore it'll cause them to not grow well. Lastly, plants anchor themselves in the soil, so if there is not much then they will not last through wind and storms.

Now, the casparian strip is part of cell wall that is chemically different on the endodermis. The endodermis is the innermost layer in some plants that lays between the cortex and the stele. It blocks the passive flow of things such as water and solutes into the stele. The stele is considered the root or stem.
