Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside 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

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

CHAPTER 1 Cell Structure and Organisation Cells * All living organisms are made up of cells * The simplest living organisms have one cell only * His name is unicellular-e.g. bacteria. * Most other living organisms have many cells- his name is multicellular- e.g. Man‚ plants‚ animals. * Cells can be seen only under microscope Cell structure All cells have the following structure in common: a) Cell membrane- a very thin layer of protein and fat‚ surrounding the cell. It is

structure of a cell to is a car. The reason I choose to do a car is because it is very similar to the structure of a cell and because to me it was the most interesting choice to choose from. Another reason I choose to compare the cell to a car is because it seemed to be the easiest one for me to do as compared to a Hogwarts or a city. Doing a house or a prison would have also been fairly easy but they were already picked by the people at my table. That wars why I choose to compare the human cell to an automobile

Animal Cell Song I’m here to talk to you about animal cells. They are made up of many organelles. Chromosome‚ nucleus‚ those are a few They need them to live like me and you. Well we’ll start with the nucleus the “command center.” It’s the brain of the cell and keeps it away from danger. It’s a safe haven for the chromosomes. They store DNA like our own. The precious DNA carries our genes. Genes tell the cell what to do like info. machines. Now let’s talk about the mitochondrion

Biology- Animal cell The NUCLEUS is the largest organelle in the majority of cells. It contains genetic information in DNA‚ which is responsible for the cells unique characteristics. The nucleus is separated from the rest of the cell by.... ...The NUCLEAR ENVELOPE is used as a barrier which separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important

generalized eukaryotic plant cell. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Plants are unique among the eukaryotes. The interiors of plant cells‚ like all eukaryotic cells‚ contain numerous organelles‚ which are membrane bounded structures that close off compartments within which multiple biochemical processes can proceed simultaneously and independently. The cell membrane of the plant cell has a phospholipid bilayer

Biology- cell organelles assignment Animal cells: Introduction: An animal cell is called a eukaryotic cell; it has a cell membrane‚ cytoplasm and a nucleus. The cell surface is covered by a membrane only. The cell membrane is strong and keeps the cell together even though it is thin and flexible. The cell membrane also controls what goes in and out of the cell e.g. nutrients go in and waste comes out. The cytoplasm is inside the nucleus and it controls the cells activities. An animal is
