and animal cells have several differences and similarities. For example‚ animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes. Animal Cell Plant Cell Cell wall Absent Present (formed of cellulose) Shape Round (irregular shape) Rectangular (fixed shape) Vacuole One or more small vacuoles (much smaller than plant cells). One‚ large central vacuole taking up 90% of cell volume.

are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell injury is hypoxic injury‚ or

Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

A well known species familiar to all is the classic‚ simple‚ ordinary goldfish; however‚ due to genetic mutation‚ a new‚ unique version of the species was born‚ the see-through goldfish. This goldfish was created due to the efforts in reducing the need for student dissections‚ as all its functioning organs are completely seen through‚ due to its pigment-less‚ fully transparent‚ scales and skin. This see-through goldfish can live up to 20 years and even get as heavy as five pounds! The mutation

Surviving in the deep‚ dark waters… How do they do it? The underwater sea creatures have their own ways of adapting to the harsh environment but they make it despite the circumstances. Between Squids‚ Zombie Worms‚ Yeti Crabs and Jellyfish‚ they all have their own unique skills to adapt. Giant Squids are located near the ocean floor. Their diet consist of mostly fish and other squids making it extremely efficient to get their source of food. The squids main predictor though is the sperm whales.

Stem cells agreement by Zayne Burnham Many scientists are now researching special types of cells called stem cells. Stem cells are very important and have the potential to cure many diseases; however there are also many issues to consider when using stem cells. Stem cells research has created concern for some in the community‚ national and international.beacause the best source of stem cells is growing human embryo. The dilemma is that the growing embryo is the earliest stage of human life extracting
