Experiment: Turgor in Potato Tissue 1. We labelled three test tubes A‚ B‚ C‚ D and added initials of people in our group. 2. Used a syringe or graduated pipette to put 20 cm3water in tube A and 10 cm3 in tube B. 3. Put 20 cm3 of 17% solution in tube C and 10 cm3 in tube B; put 20 cm3 pure sucrose solutions in tube D. 4. Working on the dissecting board I cut the ends off large potato. I was careful with the knife and cut it onto the dissecting board away from myself. 5. Used a cork

The muscle tissue of the heart is called the cardiac muscle it has 4 chambers with horizontal and vertical stripes‚ the muscle cells pump and its involuntary which means you don’t know you’re doing it. The muscle cells branch repeatedly to form a network‚ through which contracts and spread rapidly‚ each cell having a central nucleus. The muscular tissue has the ability to contract by producing movement. The heart would not function without muscle tissue because without having the

Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of

Furthermore‚ its primary function is to provide structural support of the body and has the capacity to store minerals‚ support muscle contraction resulting in motion‚ bears the load of the body and protects internal organs. The knowledge in Bone biology and its related application together with its challenges gave way to an emerging trend called the Bone Tissue Engineering. As it

Tissues to Tattoos 1. Why do some areas of the body have simple squamous epithelium and other areas have stratified squamous epithelium? Stratified squamous epithelium is used in areas of the body that undergo more abrasion (Epithelial Cells) than then areas of the body that require just having

When we’re sick we all use one thing a lot; facial tissues. We use them without even thinking about how they’re made or what was needed to make them. We just blow our noses and throw them away. You can tell how Eco foe your tissue just by what kind it is. Is it a two ply or a three ply? Is there special things in it like Vicks or not? The short life of a facial tissue starts out as a tree. Facial tissues are made from a mix of pine‚ spruce‚ fir‚ hemlock‚ larch‚ aspen and birch trees.

The primary xylem and primary phloem tissues are pushed inward into the] pith and outwards respectively by the continuous production of secondary tissues cut I off by the cambium ring. The primary xylem is gradually pushed inward and is found at the centre of the axis; whereas‚ the primary phloem‚ being soft in nature‚ gets completely crushed. These activities in the stelar region exert a great pressure outwardly. The cortex cells‚ the pericycle and the epidermis divide anticlinally to cope
