2.7.- COMPARACION ENTRE LAS CELULAS Recuerda que las celulas procarionticas son celulas primitovas que no tienen organelos rodeados por membranas. Su material nuclear se encuentra flotando en el citoplasma. Las bacterias se clasifican como procariontas. Las celulas eucariontas son las mas avanzadas y contienen organelos rodeados por membranas. Su material nuclear esta rodeado por una membrane nuclear. Las celulas de las plantas‚ los hongos y los animals son eucarionticas. Las celulas de las plantas

modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus‚ 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been widely used and abused‚ people began to treat everything with this ‘miracle’ drug. If antibiotics are continually used as bacteria grows exponentially more resistant to them then eventually society will fall back

IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between

Male System The structure and function of the human male reproductive system‚ is very similar to that of many other mammals. The male system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization. Male Reproductive System Male Reproductive System Structures 1. testes -- produces sperm and the hormone testosterone 2. scrotum -- pouch enclosing the testes keeping the sperm at an optimum temperature
