Freshwater Marsh - a wetland located near creeks, streams, rivers and lakes Temperate ponds Marine (ocean or sea) - including euphotic (sunlit) zone littoral or intertidal zones coral reef (warm shallow salt-water environments based on coral formations) estuarine biomes (where rivers meet oceans) pelagic biomes (open seas near the surface) disphotic (twilight) zone midnight (aphotic) zone benthic biomes (bottom) sea trenches sea Caves And many more. Mountain biomes: there are a lot of different mountainous biomes, from grasslands at low altitudes, taiga (coniferous forests) below the treeline, and alpine (the same as tundra) Temperate Rain Forest - cool and wet Tropical Rain Forest - warm and very wet Land Cave - cool and dark Wetlands - there are many types of wetlands, including swamps, marshes, moors, bogs, fens, sloughs, etc
Note: If you are concerned about consuming large quantities of unhealthy theatre popcorn, try carrying a small Himalayan rock salt plate and lick it during the movie. Left: The cell membrane has pulled away from the cell wall marking the onset of plasmolysis called "incipient plasmolysis." Right: The entire cell contents (protoplast) within the membrane has shrunk into a blob in the center of the cell
Amazing Cells
3D animation THE FIGHT OR FLIGHT RESPONSE When the brain detects danger or a threat, cell signaling machinery springs into action, producing a variety of responses throughout the body. interactive explore CELL SIZE AND SCALE How big are cells compared with other objects, molecules, and atoms? learn more THE EVOLUTION OF THE CELL The endosymbiotic theory explains how relatives of ancient bacteria ended up in modern-day cells
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
They are also involved in the digestion of food particles brought into the cell through infoldings in the plasma membrane Structure A membrane bound sac lysosomes are a small vacuoles or vesicles in the cytoplasm filled with digestive enzymes. Structure Each cilia (or flagella) is a circular series of 9 pairs of microtubules (often containing an additional central pair of tubules) surrounded by a long slender sheath of plasma membrane
Interactive Bacteria Cell Model
Plasmid: Plasmids are small circular DNA fragments found in the cytoplasm that contain code responsible for antibiotic resistance and other characteristics. There are numerous proteins moving within or upon this layer that are primarily responsible for transport of ions, nutrients and waste across the membrane
Labeled Plant Cell Diagram and Functions
Function: Manufactures lysosomal enzymes, translating and folding of new proteinsSmooth Endoplasmic Reticulum Similar to the structure of the rough ER, the smooth ER is a separate interconnected network membrane structure that is free from ribosomes. Function: Site of multiple cell processes including, cell metabolismGolgi Body Known as the 'golgi complex' or the 'golgi apparatus', it is located near the nucleus
All About Animal Cells
Animal cells also contain structures such as centrioles, lysosomes, cilia, and flagella that are not typically found in plant cells.Animal Cells: Organelles and ComponentsThe following are examples of structures and organelles that can be found in typical animal cells: Cell (Plasma) Membrane - thin, semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents. While animal cells come in various sizes and tend to have irregular shapes, plant cells are more similar in size and are typically rectangular or cube shaped

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
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. by email wiseGEEK Slideshows These 10 animal facts will amaze you Top 10 amazing movie makeup transformations 10 most extreme places on Earth Top 10 facts about the world These 10 facts about space will blow your mind Can you see through these real-life optical illusions? Top 10 unbelievable historical concurrencies 10 hilariously insightful foreign words You won't believe these 10 facts about people Adorable animal families that will make you "aww" Animal and plant cells have some key similarities and noted differences
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
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
Similarities Between Plant and Animal Cells
Rough ER is responsible for protein synthesis, while the smooth ER synthesizes lipids and is responsible for carbohydrate metabolism and detoxification of drugs and other poisons.

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
