ONION EPIDERMIS INTRODUCTION An eukaryote is an organism whose cells contain a nucleus and other structures (organelles) enclosed within membranes. Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole a water-filled volume enclosed by a membrane known as the tonoplast which maintains the cell’s turgor (provide structural support) and controls movement of molecules between the cytosol

Different types of cells and their ultra structure The cell is the basic unit of life. Each cell can be regarded as a metabolic compartment‚ a separate place where the chemical processes of that cell occur. Cells are often designed to perform a particular function. Depending on that function‚ each cell type has an internal structure that suits it for its job. This is known as the ultrastructure of the cell. There are different types of cells inside the human body. They are the epithelial cells‚

The Onion’s mock press release about the MagnaSoles shoe inserts satirizes how products are marketed to customers. The article is riddled through with malapropisms‚ and the whole article is a parody of an advertisement. Sarcastic irony is used when statements are made in the article that are obviously meant to show that the opposite is true‚ and hyperbole‚ or exaggeration‚ is used to show how advertisers will try to convince people that their product is useful for many more issues than it is.

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

experiment was to see whether different temperatures will affect the cell membrane‚ thus would then releases the purple pigments out of the vacuole which causes the leakage of the purplish liquid. Background Information The outermost layer is the cell wall‚ which is present only in plant cells and is made up of a carbohydrate called cellulose and also has other protein substances embedded within it. The cell wall is a rigid layer and gives structural stability to the cell and also limits the permeability

plasmoylsis and turgor in plant cells Investigation * Get a single layer of plant cells. If you are using red onion‚ cut a 1 cm square from a fleshy piece of onion and then peel off a single layer of the red cells. If you are using rhubarb‚ peel a piece from the epidermis. If you are using toadflax peel a piece of the lower epidermis of a leaf. * Place the strip on a slide and cover it with a drop or two of distilled water. Add a cover slip. * Look at the cells through a microscope. Start
