and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining; it takes in nutrients

over time 1. Living things are based on a universal genetic code a) All organisms sore the complex information they need to live‚ grow and reproduce in a genetic code written in a molecule called DNA. b) That information is copied and passed from parent to offspring c) With a few minor variations‚ life’s genetic code is almost identical in every organism on Earth 2. Living things grow and develop a) Every organism has a particular pattern of growth and development b) During development‚

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

Adaptations of Living Organisms to the Antarctic’s Extreme Conditions. The Antarctic‚ also called the south pole‚ is one of the world’s seven continents and lies at around 60° south of the equator (Singh et al..‚ 2010). The Antarctic is an example of an extreme environment. An extreme environment is a habitat that most life-forms find intolerable‚ or even‚ sometimes‚ lethal (Rampelotto‚ 2013). It is the Antarctic’s average temperature of minus 60 degrees Fahrenheit‚ average ice depth of 6‚500

It contains wide range of life forms. 1.1 What is living – Living organisms are self-replicating‚ evolving and self-regulating interactive systems capable of responding to external stimuli. Living organisms exhibit following distinctive characteristics. All Living Organisms grow: Twin characters of growth are increase in (a) mass and (b) number of individuals. Cell division leads to growth of an organism. External Growth is shown in non-living bodies where the accumulation of

Strong evidence suggests that different types of photosynthetic cyanobacteria underwent endosymbiosis that evolved into different
