Act Together Cell Theory Cells are the basic structural and functional units of life. In multicellular organisms different cells perform different functions. Different types of cells work together so that the organism functions as a co-ordinated whole Unicellular and Multicellular Organisms A multicellular organism is made up of many cells A unicellular organism only has one cell Plant Cell Animal Cell Basic Requirements Needed By Cells Cells have 3 basic

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

Understanding Haibun and Haiku Poetry through Basho’s “Hiraizumi” “Poetry is the revelation of a feeling that the poet believes to be interior and personal which the reader recognizes as his own.” ~Salvatore Quasimodo Basho’s travel journals‚ purportedly the earliest examples of haibun‚ a mix of prose and haiku‚ are often cited important reading for serious students of the form. They showed readers his Japan in a way that was both personal and that allowed us to share his journey‚ as if

a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

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
