* Hold the shape of the cell.
* Strengthen the cell.
Covering the cell membrane of the plant cell, there is the cell wall. The cell wall is composed of two
layers of rigid, hard cellulose embedded in compounds like pectin and lignin. Pores in the cell wall allow
molecules to pass through. The cell wall has two parts. The primary cell wall is formed during the growth
of the cell. After the cell has stopped growing, a secondary cell wall forms. This secondary wall is made of
lignin and cellulose, woven together tightly, to prevent further growth and to form and strong protective
* Helps dissolve waste products
* Creates a "medium" for vesicles to travel through
* Aids in cell metabolism
* Serves as a home for the cytoskeleton.
The cytoplasm is the jelly-like material that makes up much of the cell. It is 80% water and usually clear
in color. It also contains many salts. The liquid portion is referred to as cytosol. In fact, "cytoplasm" means
"cell substance." The cytoplasm is also the home of the cytoskeleton, a network of
cytoplasmic filaments that are responsible for the movement of the cell. The cytoplasm is constantly
moving and churning due to cytoplasmic streaming.
Size: Between 2 and 3µ
* Serves as "processing center" for cell.
* Packages and processes new proteins.
* Prepares proteins for secretion or storage.
The Golgi Apparatus is a series of stacked membranes in the cytoplasm that packages proteins for
secretion or storage in vesicles. Inside the membranes are sacs of fluid or gel-like substances. The Golgi
Apparatus takes proteins in transport sacs from the endoplasmic reticulum and sends it through a series of
these membranes. The proteins are then "modified"' as they pass from membrane to membrane. After the
vesicle of proteins has finished its trip through the Golgi Apparatus, it buds off the organelle in a Golgi sac,
ready to be stored or transported to other parts of the body.
Size: 7 to 8 NM (nanometers)
* Controls what enters and exits the cell.
* Separates cell from outer environment.
On the outside of all cells, there is a layer of protein and lipid (fat) called the cell membrane or the
plasma membrane. This membrane is found in ALL cells. The membrane is selectively permeable, meaning
it allows some molecules to enter and some not to. The membrane allows molecules in through two forms

- What is a cell. According to Genetic Home Reference, “Cells are the basic building blocks of all living things.” There are two main branches in which a cell can be categorized. These branches are prokaryote and eukaryote. In the prokaryote category are bacteria; in the eukaryote category are plants and animals. Although plant and animal cells have a lot of differences, they also have their fair share of similarities. For instance, an animal cell has a centrosome, but so does a plant cell. An average animal cell is made up of centrioles, cytoplasm, endoplasmic reticulum (smooth ER and rough ER), golgi complex, lyosomes, microtubules, mitochondria, nucleus, nucleolus, necleaopore, and ribosome...

- Our planet, the Earth, is the third planet from the Sun, and usually is known as the Blue Planet. Its location in the Solar System and the particular characteristic of being the only planet with abundant water, have made possible the development of life here. Thousands of millions of years ago, the first living organisms evolved from a non-living matter, and since then the Earth has been inhabited by many different species. Those, who have dedicated their research to study and classify living organisms, best known as taxonomists, have divided them into categories, taking as a definition pattern the principal features of each species....

Water in plants Water plays a critical role in plants as it makes up 85% to 95% of the plants’ weight and 5% to 10% of the seeds’ weight which makes it the most abundant complex in plant cells(1995). Water is also involved in organic compounds synthesis, support the plant(95). Reactions occur in water, and solvents move in the water(95).... [tags: Cell wall, Osmosis, Cell, Plant cell]

Arbuscular mycorrhiza The most common and abundant mycorrhiza is AM which belongs into the endomycorrhizas and inter alia associates with approximately 74% of all Angiosperm plant species, number of Gymnosperm species and some Cryptogamic species (Brundrett, 2009)....

- Opposite of bacteria, plant and animal cells divide using a process called mitosis. Mitosis begins after the same basics steps in plants and animals, but there are some exceptions. Also, mitochondria divide and are pass out to both daughter cells. In photosynthetic plant cells, chloroplasts must also divide and be given away to both daughter cells. Plant cells lack the structures found in animal cells that are called centrosomes, so the spindle fibers in plant cell mitosis proceed from a structure called the microtubule organizing center....

- Animal Cells vs. Plant Cells Introduction Cells are the basic units of life, and they can be found everywhere that you look and go. Most cells cannot be viewed without the aid of a microscope. Plant and animal cells are very different not only in their structure shape but in their functions as well. The diagrams found in the book on pages 65-66 are described as generalized cells that are used for study purposes (Mader & Windelspecht, 2016). According to Carl Woese, a professor of microbiology at the University of Illinois, eukaryote cells are more structurally complex than those of their prokaryotic counterparts....

- stress, thereby inhibiting leaf expansion after the loss of cell turgor pressure (Iqbal and Ashraf, 2005). Principally, reduction of cell turgor pressure leads to stomatal closure and limits CO2 assimilation and reduced photosynthetic rate resulting lessening of chlorophyll content, which ultimately responsible for lowering of plant biomass because of low production of photosynthetic assimilates (Netondo et al., 2003). However, some researchers discovered that the roots are less affected by salinity and increase of root-shoot ratio will enhance absorption of water and nutrient, and strengthen the capacity of the plant in saline resistance and in poor soils, which was helpful for the plant to...

membrane or carrier molecules. Active transport consists of endocytosis, exocytosis, and the sodium-
potassium pump. The membrane also protects the cell from the outside environment, keeping the cytoplasm
and its organelles in, and all of the stuff outside out.
Size: 2 to 3 µm
* Serves as "respiration" center" for cell.
* Makes energy for the cell.
Floating inside the cytoplasm are a series of fairly large organelles called Mitochondria. These
organelles, the size of some bacteria, serve as the cell's respiration centers, the place where energy for the
cell is produced. Since the Mitochondria serves as a center for energy production, there are varying
numbers of mitochondria in different cells. Muscles have many mitochondria due to the amount of energy
they need, but skin cells have very few. The mitochondria (singular: mitochondrion) have two membranes.
The outer membrane protects the organelle, and the inner membrane is folded into a series cristae or long
Size: Highly variable
* Serves as "transportation system" for cell.
* Moves proteins and vesicles around cell.
The Rough Endoplasmic Reticulum (or ER) serves as a home for the ribosomes of a cell and as a
"highway" for the cell's proteins to be transported on. Being close to the ribosomes allows for the quick
transfer of proteins from them to the rest of the cell. This "highway" is composed of interconnected
membranes and vesicles. The process of transporting these newly created proteins is critical to the cell, and
is required for furthur survival. The ER is very closely associated with the Golgi Apparatus.
Size: Varies from 10+µ to quite small.
* Serves as large storage centers for cell.
* Hold water and many nutrients
Inside the cell, surrounded by the cytoplasm, is the vacuole. In a plant, the vacuole acts as an extremely
large storage area, and serves as a "control" for the turgor pressure in the cell. The vacuoles that perform
the latter are called contracile vacuoles. They take on excess water and then squeeze it out of the cell to
prevent cytolysis. The other task of the vacuole is also very important. It stores enzymes and toxic wastes
that cannot be stored anywhere else in the cell. Usually, there is only one vacuole per plant cell, and it can
take up to nearly 90% of the cell's total volume.
