The cross-sections demonstrated the basic differences that distinguish a monocot plant for a dicot plant. When looking at the cross-section of the monocot stem you can see that the vascular bundles are scattered. These vascular bundles consist of only a phloem and xylem. The phloem is responsible for transporting soluble compounds (food) created by photosynthesis, to the rest of the plant, especially where they are needed. The xylem is important for the movement of water throughout the plant. Another difference that can be seen by looking at the cross-section of at stem is that the ground tissue (parenchyma) is not partitioned into pith and cortex. In the dicot stem cross-section the vascular bundles form a ring and they are made up of a phloem, xylem, and a cambium which divides the two. The ground tissue (parenchyma) for a dicot is separate into a pith (nutrient storage and distribution) and a cortex (conducting tissues). The Leaf cross-sections reveal the venation of each plant. For monocots, the veins appeared run parallel to each other, while the veins for the dicot plant had no clear pattern. The root cross-sections also displayed differences between the groups belonging to the phylum Anthophyta. The root cross-section of a monocot is formed by vascular bundles that are arrange in a ring. In the dicot root cross-section, the xylem is at the center in the form of an

The leaves of a plant are the main photosynthetic organs and are involved in gas exchange and water transportation throughout a plant (Evans et al, 17). A leaf typically consists of an upper and lower epidermis, the mesophyll cells, veins, guard cells and stomata. The mesophyll cells contains spongey cells which have large gaps between each cell to allow oxygen and carbon dioxide circulation. The mesophyll cells contain palisade cells, which are located beneath the upper epidermis. The palisade cells contain many chloroplasts, which are green organelles. Located in the internal layers of chloroplasts is the pigment chlorophyll which is involved in trapping the light energy in photosynthesis (Evans et al, 17).

The phrase “tree seeds” shows growth. At the end of its growth, the tree sprouts into a beautiful tree. Like the sprouting seed, there are seventeen phases to accomplish . White belt, yellow belt, yellow senior belt, orange belt, orange senior belt, green belt, green senior belt, blue belt, blue senior belt, purple belt, purple senior belt,

Plant cells have selectively permeable membrane that allows selective substances to penetrate into the cell. Cell membranes are consisting of lipid layer that are made up of phospholipids. (Essays, UK.2013). These phospholipids are amphipathic in nature, which have phospholipids head and tail respectively. Phospholipids heads are hydrophilic and tails

Diffusion, osmosis and active transport of substances in and out of the membrane is very important for all types of cells. One example is the root hair cell. These cells are the exchange surface in plants which are responsible for the absorption of water and mineral ions so without osmosis and active transport this would not be possible. The water is taken up by osmosis through the partially permeable membrane. The root hair cells are surrounded by a soil solution which contains small quantities of mineral ions but mainly water, so has a high water potential (slightly less than zero). The root hair cells themselves contain a high quantity of amino acids, mineral ions and sugars inside them (low water potential). Therefore water will move by osmosis from the soil solution and into the root hair cells, going down the water potential gradient.

Despite its importance osmosis may also damage cells by causing them to; a) shrink from water loss or b) burst from too much water gain. Plant cells [fig 3] have adapted themselves to ensure that these factors do not affect them, by forming a ridged wall, known as the cell wall, around their cells. The cell wall maintains the shape of the cell, and prevents the cell from bursting in a hypotonic medium by resisting water pressure. Plant cells have also adapted a larger vacuole, which occupies 80% or more of the cells cytoplasm (Davidson, 2004); allowing plants to store more water and nutrients per cell. Vacuoles also play a structural role in plant cells; by swelling when liquids contact them, plant vacuoles are able to control turgor pressure within the cell. This helps maintain the structural integrity of the cell as well as providing the plant with suitable amounts of water and nutrients; however the cell will never burst because the vacuole is contained within the cell wall. If plant cells are deprived of water their vacuole will begin to shrink, yet due to the cell the wall, the plant cell will be able to maintain its shape.

The Power of Hoping I had never voyaged alone nor had any kind of independent occurrence until the summer of fifth grade. Going to overnight camp was always a topic of conversation in my family. My grandmother, aunts, and mom all experienced summers up in serene Maine, and it was finally my turn to undergo what they had. Despite being an “unaccompanied minor,” I boarded a plane to Maine, eager to start my journey. I was picked up by a counselor who then drove me to my new home for the next month.

Second off we have the plant cell. The plant cell has chloroplasts unlike a animal cell (Doc.1). Chloroplasts hold

The tree itself is ancient; you have been told that most Fruit trees live, at most, fifty years, but this one has grown wide around the trunk and long in the branches. Despite its age, it still makes fruit. The tree makes almost every fruit in the world. Some say that this is the fruit tree after which the monastery was named, a true immortal tree. Other believe it to be a descendant of the original Fruit True. The Fruit Tree’s branches extend over a lake around the tree and reflects on it. It is normally a very peaceful spot, but now the atmosphere it thick. Abraham stands there with Master Shen, the oldest teacher in the

Water diffuses across the membrane from the region of lower solute concentration (higher free water concentration) to that of higher solute concentration (lower free water concentration) until the solute concentrations on both sides of the membrane are equal. The diffusion of free water across a selectively permeable membrane, whether artificial or cellular, is called osmosis. The movement of water across cell membranes and the balance of water between the cell and its environment are crucial to organisms. ("Diffusion And Osmosis - Difference And Comparison | Diffen"). A semi-permeable membrane known as the cell membrane surrounds the living cells of both plants and animals. Both solute concentration and membrane permeability are taken into account in the ability of a cell to gain or lose water. If there is a higher concentration of solutes in the surrounding solution, water will tend to leave the cell, and vice versa. The membrane forms a selective barrier between the cell and its environment and does not allow toxic substances from the surroundings to enter into the cell (Deena T Kochunni). The selective permeability allows the cell to regulate the flow of necessary substances into and out of the cell. In plants osmosis is also responsible for absorbing water and minerals from the soil by using the semipermeable membrane of the root (Deena T Kochunni). If the extracellular fluid has a lower osmolarity than the fluid inside the cell, it’s said to be

Plants rely on receiving their nutrients and water through soil. This is able to be done by a special kind of diffusion, called osmosis. Osmosis is when fluid passes through a semipermeable membrane to an either low or high concentration separating the two solutions. These high and low concentrations, will consists of having solute in each. Water will pass through the membrane, until each side is equal in concentrations. Although

In times of the past, farmers would take the pollen from one plant and cross pollinate that with that of another plant to create a hybrid of the two plants to have traits from both. This was often done to create a stronger plant or one that would yield larger or

For a horticulturist, the solution is simple. When an Esrog tree starts to grow, it is grafted onto the rootstock of other hardier and more resilient citrus trees, most often of the lemon or orange. The resulting tree will be much stronger and more resistant to disease, require less care, and have a doubled life-expectancy. The tree will also produce more plentiful and robust fruit.
