contain nonphotosynthetic organisms‚ most or multicellular and they digest food externally. Plantae contain photosynthetic multicellular organisms‚ precise numbers are difficult to determine‚ but as of 2010‚ there are thought to be 300–315 thousand species of plants‚ of which the great majority‚ some 260–290 thousand‚ are seed plants. Animalia are nonphotosynthetic organisms‚ they are also multicellular like the fungi kingdom‚ but they digest there food internally. Viruses are very small infectious

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

evolve as a reaction to predators as defense. They evolved because food was becoming more complex and not something that they could suck up and digest simply by having them go straight into the stomach. More complex algae and seaweed evolved and the “herbivores” needed to break these down and get these into their mouths and these algae would take too long to digest in the stomach and couldn’t simply be taken by vacuum. Predators also needed a way to break

Unit 5 P1 Animal Cell Nucleus- the nucleus in an animal cell controls every activity that happens within the cell Cell membrane- The cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane

For example: When cows are fed corn‚ usually genetically modified corn‚ it makes them sick to their stomach--literally. Cows are actually one of the only creatures that can digest grass and turn into fuel. But‚ By the time a modern American beef cow is six months old‚ it

Fibrosis is caused by a single faulty gene that controls the movement of salt in the body. In people with Cystic Fibrosis‚ the internal organs become clogged with thick‚ sticky mucus resulting in infections and inflammation making it hard to breathe and digest food. For a baby to be born with Cystic Fibrosis‚ both parents must be carriers of the faulty CF gene. The diagram shows how CF is inherited. Where both parents carry the faulty gene‚ each child has a one in four chance of having CF‚ a two in four
