confused as I thought that the bigger one was called small vacuole. Not only did I learn that the central vacuole is responsible for regulating the waste in a plant cell but also that they are larger in plant cells than in animal cells. The correct answer was Central vacuole because this picture shows a plant cell and in the plant cell the vacuole is much larger. E: The reason why I choose chloroplast was because I remember that the chloroplast was small and round so I was confused between the

Cell membrane - forms the outer covering of the cell, and is semi-permeable. Cytoplasm - is a gel-like matrix where all the other cell organelles are suspended inside the cell. Nucleus - contains the hereditary material DNA and directs the activities of the cell. Centrioles - organize the microtubules assembly during cell division. Endoplasmic Reticulum - are a network of membranes composed of rough and smooth endoplasmic reticulum. Golgi complex - is responsible for storing, packaging

Anatomy and Physiology Cell Organelles There are 50 trillion (50 million million) cells in the human body; they carry out chemical reactions essential to life, for example Blood cells. Nucleus The nucleus is the largest structure in any human cell, it contains gasps or pores, which allow protein and nucleic acid, pass through. It is the central part of the cell and it’s usually a lot darker than the rest of the cell because it absorbs stain quickly and stores the entire DNA (Deoxyribonucleic

Parts of a Cell There are two types of cells: Image 1 (Kaufman and Thompson) Prokaryotic Cell Image 2 (Kaufman and Thompson) Eukaryotic Cell A prokaryotic (pro- before; karyotic-nucleus or before the egg) cell does not have a true nucleus. A eukaryotic (eu- true; karyotic- nucleus) cell has a nucleus surrounded by a nuclear membrane. Let’s start with the CELL MEMBRANE Image 3 (Hese) Pretend the cell is a house

engineering removes part of the DNA of one species, then combines it with the DNA of a totally different species [that would never breed together naturally]. This is done by manipulating the biochemistry of the DNA during cell division (splitting of one cell into two new cells) and DNA replication (producing two identical copies of the cell’s genetic material). …For example, … part of the DNA from Bt bacteria, [is] inserted into the DNA of corn, to produce a totally new species of corn [Bt-corn]

Cell Essay This is my essay for converting a cell into a city. I started out with creating a cell wall. I made a Nordic wall of stone to protect the city. Next I did the cell membrane which I transformed into a draw bridge to fit the theme. For the cytoplasm I put grass because it makes up the shapes of the cell/city. The next big project was the chloroplast which I turned into solar panels and smokestacks because it takes in sunlight and releases CO2. On the inside I put greens and vines. The

Adrenoleukodystophy (ALD) Understanding an Animal Cell: Basic Units of Life The cell is the fundament unit of life. They make up the smallest level of a living organism in the human body, where the metabolic processes happen to in order to maintain life. It itself is considered a mini-organism made up from organs called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell contains the following organelles (Tracey

of the 21st chromosome in every cell. In medical terms “trisomy” refers to having an extra copy of a chromosome. The proper name for down syndrome is Trisomy 21 because of the extra copy of the 21st chromosome ("Facts about Down Syndrome”). Mosaicism occurs when a child is born with an extra chromosome in some but not all of their cells. Mosaicism normally has less severe symptoms than trisomy 21. Translocation down syndrome occurs

cloning it is the whole genetic of a single individual. There are different methods to do with this type of cloning but the most common is somatic cell nuclear transfer. The first step is to remove the nucleus from the mother egg. Second is to take a somatic cell from the individual being cloned, take out the DNA and put it in the egg of the mother. Then the cell that is formed from putting the two together is then induced to divide and form an embryo.
