Living Environment/Biology A Tour of the Cell CellsTissuesOrgansOrgan SystemsOrganisms *Cells are made up of smaller functional parts known as cell organelles (little organs). Cell organelles are specialized cell structures that perform specialized jobs in the cell.* 1. Cytoplasm- *Jelly-like substance inside of the cell 2. Mitochondria- *In cellular respiration oxygen is used to extract energy from sugars‚ fats‚ and other nutrients 3. Cell membrane- *It is a selectively permeable

BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

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

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

Measuring the Effect of Light Intensity on Photosynthesis Introduction Photosynthesis captures energy from sunlight. Plants‚ algae‚ and some bacteria use the energy captured during photosynthesis for their metabolic reactions. During photosynthesis in plants‚ chlorophyll and enzymes in leaves convert certain wavelengths of light into chemical energy. A simple equation can be used to represent photosynthesis. Enzymes and Chlorophyll light energy CO2 H2O carbohydrate O2 In this investigation

* Food: Omnivores or scavengers feeding on dead or decaying plants or animals. Some may eat live plants. * Habitat: Breath with gills‚ need a moist environment‚ under rocks for example. * Predators: Vertebrates and invertebrates. * Interesting behaviors: Pill bugs: curl up into a ball for when feel attacked or insecure. * Impact on the ecosystem: Positive: food for other animals Negative: can eat and damage plants * Where to find: Under logs‚ moist leaf liter‚ in pet food

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process that breaks down food to use as energy. The three main stages are glycolysis‚ citric acid cycle‚ and electron transport (Simon‚ Reece‚ & Dickey‚ 2010). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? During glycolysis‚ a team

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan
