The Great Cell WebQuest
Drag and Drop Cell Organelles - Test your knowledge of the cell by matching each structure with it's function by dragging the organelles to their proper spaces. Hold on, we're in for a rough ride! Task G'day, mate! We're getting ready to take you on the journey of your lifetime! It's been donkey's years since I've done this! You will be shrunk down to the size of a water molecule
The History of Animal Evolution
Their hard outer exoskeletons provided protection and would help to retain water, although the development of a waxy, waterproof cuticle was necessary for efficient water conservation. This unique situation was the starting point for the great evolutionary diversification of the mammals, which up until then had been nocturnal animals the size of small rodents
The Cell - Prokaryotic and Eukaryotic Cells
DNA in a prokaryotic cell is not separated from the rest of the cell but coiled up in a region called the nucleoid.As organized in the Three Domain System, prokaryotes include archaeans and bacteria.

The smallest structural unit of an organism that is capable of independent functioning, consisting of one or more nuclei, cytoplasm, and various organelles, all surrounded by a semipermeable cell membrane. a device for converting chemical energy into electrical energy, usually consisting of a container with two electrodes immersed in an electrolyte See also primary cell, secondary cell, dry cell, wet cell, fuel cell 6

In addition to having a nucleus, plant cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation
Interactive Cell Models
Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells
Interactive Eukaryotic Cell Model
Smooth ER plays different functions depending on the specific cell type including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and control of calcium release in muscle cell contraction. Smooth Endoplasmic Reticulum: Throughout the eukaryotic cell, especially those responsible for the production of hormones and other secretory products, is a vast network of membrane-bound vesicles and tubules called the endoplasmic reticulum, or ER for short

30 PamloAug 11, 2011 @ 11:11 amThis a good one but I am afraid i did not get what i wanted 31 AudrinnaAug 25, 2011 @ 6:18 pmI think there should be more about the unknown parts of the cell. The matrix, or inner space created by the cristae, contains the enzymes necessary for the many chemical reactions that eventually transform food molecules into energy
According to the Cell Theory, all living things are composed of one or more cells, and the functions of a multicellular organism are a consequence of the types of cells it has. No matter which type of cell we are considering, all cells have certain features in common, such as a cell membrane, DNA and RNA, cytoplasm, and ribosomes
September 25, 2012 at 8:24 pm Nikita Thanks a lot! It really helped me with my revisional Bio questions! October 3, 2012 at 7:18 am mukesh kaushik Very good ,i have taught my students .thanx October 4, 2012 at 10:58 pm kawneer THANK YOU IT HELPED ALOT !!!!!!! November 12, 2012 at 7:18 pm Justin thanks this helped a lot when i was tutoring.. Instead, use the methylene blue solution as the dye Observations When observing the onion skin cell, we noticed that the cells took on a brick-like structure and within the cells, small dots (the nuclei) can be seen
During this process, electrons are shuttled through an iron-containing cytochrome enzyme system along membranes of the cristae which result in the phosphorylation of ADP (adenosine diphosphate) to form ATP (adenosine triphosphate). In fact, chloroplast DNA, including the protein-coding RBCL gene, is often used at the family level to show the relationships between genera and species within plant families
The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP. Water flows across the respiratory surface of the gill in one direction while blood flows in the other direction through the blood vessels on the other side of the surface
What are Some Differences Between Plant and Animal Cells?
me and my cousin canesha was trying to search google and couldn't find anything but then we went to ask.com and they recommended this website and we had gotten a lot of information and my cousin was saying that my teacher was going to say this was a lot of information for just a 7th grader. Understanding basic cell structure helps to understand how the cells differ from each other, and they do differ in important ways, as plant cells provide different functions for the plant than animal cells provide for the body
The animal kingdom is unique among eukaryotic organisms because most animal tissues are bound together in an extracellular matrix by a triple helix of protein known as collagen. The process of cell fractionation enables the scientist to prepare specific components, the mitochondria for example, in large quantities for investigations of their composition and functions
Structure and Functions of Cytoplasm
The function of this organelle is to produce and store energy in the form of adenosine triphosphate (ATP) molecules, which are generated by using the chemical energy derived from food. However, the smooth operation of all these functions depends on the existence of cytoplasm, as it provides the medium for carrying out these vital processes
Plant cells vs. Animal cells - Biology Online
A plant cell is bounded by a cell wall and the living portion of the cell is within the walls and is divided into two portions: the nucleus, or central control center; and the cytoplasm, a fluid in which membrane bound organelles are found. The proteins synthesized on ribosomes bound to granular endoplasmic reticulum are transferred from the lumen (open space inside endoplasmic reticulum) to the golgi apparatus for secretion outside the cell or distribution to other organelles
Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles. parts of animal cell cell membrane, cytoplasm, nucleus 5According to the cell theory, proposed over 150 years ago Most cells are very tiny and can only be seen with the aid of a microscope
Plant and animal cells are both eukaryotic cells, so they have several features in common, such as the presence of a cell membrane, and cell organelles, like the nucleus, mitochondria and endoplasmic reticulum. Cellular respiration occurs in mitochondria on animal cells, which are structurally somewhat analogous to chloroplasts, and also perform the function of producing energy
Plant and Animal Cell Structures
Created with CAST's UDL Book Builder Golgi Body The Golgi Body packages and transports proteins, and holds waste products until the cell is ready to get rid of them. This is a semi-permeable membrane, in that it allows some things in such as water and food molecules, but keeps out other things that may be harmful or unnecessary
