    The cell is the basic functioning unit of organisms in which chemical reactions take place. These reactions involve an energy release needed to support life and build structures. The cell consists of membrane bound organelles‚ which are responsible for the division of labour. There are two main classes of cells- Prokaryotes which are cells without a nucleus‚ where the DNA is spread around the cytoplasm of the cell‚ an example of a prokaryote is a bacterium (See Figure 1). The other class is the Eukaryotes

    Analysis of the Poem “Mending Wall” by Robert Frost This poem is about a time when the author went up to fix the stone wall that stood between his property and his neighbors. The poem talks about the experience and the authors thoughts about the experience. “something there is that doesn’t love a wall” The author is wondering‚ probably as he travels to the wall‚ what it is that might destroy a wall. What exists that does not want a wall to stand. “that sends the frozen-ground-swell

    An example of a specialised animal cell could be of a nerve cell. The nerve cell contains axons of motor and sensory neurons‚ which are in bundles of fascicles. They are surrounded by connective tissue which is the sheath of perineurium which ensures that the cells do not get damaged. This lso helps do that the function of the cell is carried out correctly (Nerve Anatomy or Structure (Expanded View)‚ 2017). The function of a nerve cell is to emit impulses through electrical signals fromt the brain

The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices

    Lab Report Comparing Animal and Plant Cells The cell is the fundamental structural unit of all living organisms. Cells help carry out the functions of life and together support the organism to function as a whole. Cells are divided into two main categories of eukaryotes and prokaryotes. Animal cells and plant cells fall into the division of eukaryote cells that have both a nucleus and organelles. In this lab‚ animal and plant cells will be compared through a microscope to identify differences

    typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers (nm)) thick‚ which is partially permeable. It consists mostly of lipids and proteins. The lipids found in cell membranes

    Cell division consists of two processes: mitosis and cytokinesis. Mitosis— division of the nucleus and its chromosomes— is divided into five phases:prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. Mitosis is followed by cytokinesis‚ when the cytoplasm splits to form two separate daughter cells. The cytoplasm of a cell in late interphase contains two centrosomes‚ each of which may contain a pair of centrioles. In the nucleus‚ the chromosomeshave been replicated during S phase‚ but are
