The Structure Of Animal And Plant Cells

For a plant cell, the nucleus, without a doubt, is the most important organelle; but in the animal cell, the most vital structure is the mitochondria.

The fluid surrounding the cells called tissue fluid are bother watery environment. Also, it’s the outside of any large cell. The function is to protect the cells from the surroundings. It also allows things to enter in and out of the cell this will maintain the support of cell and shape. Nucleus

According to Mattias Schleiden and Theodor Schwann the cell is the basic unit of life(Cell Theory- OI). Two common types of cells are the plant and animal cells. Although both kinds of cells share many similar, abundant structures, they also have varying descrepancies from cell to cell. Without a doubt, the nucleus is the most important organelle in the plant cell, even though, the lysosome is the most important structure in the animal cell.

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

The nucleus is enclosed in a nuclear membrane which has pores to allow RNA and proteins. The nucleus functions the activity in a plant cell and stores the plant’s DNA. (Plant Cell Anatomy, n.d.)

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.

These parts are all paired to parts of cells. A quarterback is compared to a ER because it throws the whole game when he throws the ball. A cell wall is compared to the center because it protects the quarterback to throw the ball. A football field is compared to the cytoplasm because it is where all the players are at. A coach is like the nucleus because it controls the plays and tells the play. A golgi apparatus is compared to the running back because it sends the

This is made possible by the support lent to it by the slightly elastic cellulose cell wall. It will support a turgid cell enough to prevent it from bursting (see left). It is turgid cells such as this that provide a plant with its support. Animal cells on the other hand, do not have supporting cell walls, just cell membranes. As plants are always surrounded by water, it is vital for them to have cell walls, but animal cells, surrounded by blood (low water concentration), do not need as much support.

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

Nucleus: The nucleus controls the cell. like the cork of a baseball controls the trajectory and the direction.

The Cell wall is a hard, rigid layer that surrounds the cells of fungi, bacteria, and plants. The cell wall is located just beyond the cell membrane. The key purpose of the cell wall is to provide structure, flexible power, structure support,

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.

In regards to their basic structure, according to the SEER Training website, “cells consist of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.” (Training.seer.cancer.gov, 2017) This is true for animal cells however plant cells contain a fourth part which is known as the cell wall, it is located on the outside of the cell membrane and allows the cell to keep its rigid shape. It should also be known that there are types of cells that do not contain a nucleus, these are called prokaryotic cells and generally still have the same characteristics as cells that do have a nucleus which are known as eukaryotic cells. (Study.com, 2017) As seen in Figure 1 cells also contain organelles which keep the cell alive and allow it to function effectively.The cytoplasm of the cell which resides between the cell membrane and the nucleus is a gel-like liquid filling the inside of the cell. The cytoplasm allows the cell to have shape and allows the cell 's organelles to move around the cell as needed and function correctly. The nucleus is widely considered to be the control center or

Organelles are the internal structures of the cell that are important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles in plant cells. Lysosomes are also rarely found in plant cells but mostly found in animal cells.
