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

Cytoplasm Cell Membrane Nucelous Nuclear Envelope Nuclear Pore Lysosomes Microtubles Microtubules- Is a component of the cytoskeleton. Centriole- Aids in cell division and it’s only in animal cells. Lysosomes- Clean-up organelle it digests and breaks down lipids‚ carbs‚ and proteins. Nuclear Pore- Dots on the envelope which allows material in the and out of the nucleus. Cell Membrane- It surrounds the cell and regulates what enters and leaves the cell. It is selectively

Background Information: Cell Transport When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires energy? ACTIVE Which CELL PART provides the energy for

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

Chapter-8 Cell: The Unit Of Life What is a cell? Cell is the basic or fundamental structural and functional unit of an organism. What is cell biology? The branch of biology that deals with the study of cell structure and function is called cell biology. DISCOVERIES; Who discovered cell? Robert Hooke observed a live cell in 1665. He observed the cell(actually the cell walls) in the slice of cork under his compound microscope ‚coined the term cell‚ recorded his observations in micrographic

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

Imagine a busy factory making the latest must-have toy. Whether they make bicycles‚ cell phones‚ or hot air balloons‚ most factories are set up the same way. All factories have outside walls that protect and support them and inside walls that create different work areas. They usually have a production line where a product is put together and an executive department that decides what product is made. A finishing department processes and prepares the product for shipping‚ and a packaging department

Germany’s political division’ To what extent do you agree? I agree to a certain extent with the statement as although it initially seems that the First World War narrowed the existing political divisions within Germany in this period‚ as the war proceeded‚ the resentment greatened‚ in part due to huge losses and the economic crisis that prevailed over the country. Therefore because of this the political divisions increased‚ and by the end of the war the polarisation (division) of German politics

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
