eukaryotic organelles. ”A eukaryotic cell is sectioned by internal membranes into different functioning categories called organelles. For example‚ the nucleus houses DNA‚ the genetic component that controls the cells activities. (Boundless. “Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also gives the cell its shape. The Nucleus or the brain

Plant Cell Plant cells are eukaryotic cells or cells with membrane bound nucleus. Generally‚ plant cells are larger than animal cells and are mostly similar in size and are rectangular or cube shaped. Plant cells are similar to animal cells in being eukaryotic and they have similar cell organelles. What is a Plant Cell? Back to Top Plant cells are eukaryotic cells i.e.‚ the DNA in a plant cell is enclosed within the nucleus. The most important distinctive structure of plant cell is the presence

Title: Animal and Plant Cell Structures Instructions: Your lab report will consist of the completed tables. Label each structure of the plant and animal cell with its description and function in the tables provided. When your lab report is complete‚ post it in Submitted Assignment files. 1. Animal Cell: Observe the diagram showing the components of an animal cell. Using the textbook and virtual library resources‚ fill in the following table: Animal Cell |Number

Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into

Animal cells vs. Plant cells Five Similarities Animal and plant cells have many of the same characteristic. Animal cells and plant cells are both eukaryotes. They both have cell nucleus which contain chromosomes or DNA‚ as well as cell membrane encompassing the cell to control the substances moving in and out of the cell. They both contain enzymes from liposome for breaking down larger molecules. Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum

concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs
