When Robin Hooke Cell
Task 1 (B)
When Robin Hooke in 1665 first observed a cell under a basic microscope, he was unsure of the function of these cells. Hooke couldn’t see any indication of any main cellular organelles that we now know to exist within each individual cell. Due to advances in technology and ever evolving research, it is now widely evident that cells are fundamental to life. Each cell has a series of cell organelles and each of these organelles has a structure and function within the cell. Animal cells and plant cells have mutual organelles, although plant cells have organelles that animal cells do not have.
The cell membrane keeps the cell organised and separate from other internal surroundings. Cell membranes protect the cell from other factors within the body, allowing the other organelles within the cell to carry out their functions successfully. The cell membrane is semi-permeable allowing individual molecules to move within it. The cell membrane has a bilayer of phospholipid molecules, this bilayer has integrated proteins to allow transportation of materials in and out of the cell.

The nucleus controls all growth and reproduction within the cell and is seen as the most significant organelle within the cell. This organelle is enclosed within a double membrane, with the exterior membrane connected to endoplasmic reticulum and the interior membrane connected to nuclear pores. This double membrane protects the nucleus from the rest of the cell, ensuring that the DNA contained within the nucleus is fully protected.
Mitochondria is an organelle that helps produce energy for the cell. Like the nucleus, the mitochondria is enclosed within a double membrane. The inner membrane is folded increasing the surface area of the

Mitochondria- termed as the “powerhouse of the cell,” the mitochondria is responsible for the production of ATP and cellular respiration. Energy is converted in this structure and used for the different activities that take place within the cell. 5.

The cell membrane is selectively permeable and the turnstiles or gate only let people with a ticket into the stadium 2. Cell Wall - The cell wall in a cell is just like the support beams of a baseball stadium.
Overview Of Your Inner Fish By Neil Shubin
905 Words | 4 PagesThere is a common misconception about the field of paleontology. Many people believe it’s boring, that it’s irrelevant, and that it’s even a waste of time. However, as award winning paleontologist and author Neil Shubin argues in his novel, Your Inner Fish, the field of paleontology has the potential to change the way we view our bodies. Shubin rose to fame in the mid ‘00s after discovering a brand new fossil on the coast of Ellesmere Island. This fossil was of a creature that was part land animal and part fish, containing the flat head and joints of a land animal and the fins and webbing of a fish.
Essay On Henrietta Lacks
817 Words | 4 PagesThese cells are known as HeLa. HeLa cells contributed lots of scientific knowledge, but were also a curse to the Lacks family. Key Idea 1: The Anatomy of Cells Today, science textbooks everywhere are filled with the anatomy and structure of cells. We can credit much of this knowledge to HeLa.
Summary Of The Lives Of A Cell By Thomas
353 Words | 2 PagesThe Lives of a Cell the essay shares a characteristic structure by comparing the complicated cell life to us humans . Thomas does this in the essay by offering a theory which will provide unity and cohesion. In some cases, he echoes the accepted wisdom in the scientific community. On occasion, however, he will challenge the theories and conclusions set forth by his colleagues, even when he is reflecting on a subject in which he is not an expert. In addition to a common structure, all the essays are linked together by two themes.

308 Words | 2 PagesWhat three statements make up the cell theory? The three statements that make up the cell theory are all living things are made up of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells. 1c. How did the invention of the microscope help the development of the cell theory?

543 Words | 3 PagesEven though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.

860 Words | 4 PagesThe nucleus is generally in the center of a cell. A typical cell nucleus is so small that ten thousand could fit on the tip of a needle. One strand of DNA is around 6 feet long. This mean that 6 feet of DNA fits inside the nucleus, which occupies about 10% of a total cell (https://en.wikipedia.org/wiki/Cell_nucleus), of a microscopic cell. For this to happen eight separate histone protein subunits attach to the DNA molecule to

When waste products are present the cell membrane gets rid of it and the cell membrane allows important things inside . A great example of what the cell membrane allows in or out is water and oxygen. Specific molecules are only made to enter the cell which is also called semipermeable. Molecules can be passed by active transport or either passive transport.
Eukaryotic Cells Research Paper
208 Words | 1 PagesThis diagram identifies the eukaryotic cell is more evolved than the prokaryotic cells and has a more complicated structure. Eukaryotic cells are what makeup animals and plants. Unlike the prokaryotic cells most eukaryotic cells contain a nucleus surrounded by nucleoplasm within its own membrane and the eukaryotic cell contains many more types of organelles than the prokaryotic cell. The nucleus contains the DNA of the cell and coordinates the cells functions that include growth, reproduction, metabolism and protein synthesis. On the edge of the nucleus are nuclear pores, this allows the nucleus to communicate with the rest of the cell, found within the nucleus is the nucleolus a dense structure of a crystalline protein and nucleic acid used
Nucleus Organelles
147 Words | 1 PagesTypically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis. The nuclear envelope is a double-membrane structure that constitutes the outermost portion of the nucleus. Both the inner and outer membranes of the nuclear envelope are phospholipid bilayers.

Darwin's Black Box Analysis
589 Words | 3 PagesThe field of biochemistry, begun when Watson and Crick discovered the double-helical shape of DNA, has unlocked the secrets of the cell. There, biochemists have unexpectedly discovered a world of Lilliputian complexity. As Behe engagingly demonstrates, using the examples of vision, blood clotting, cellular transport, and more, the biochemical world comprises an arsenal of chemical machines, made up of finely calibrated, interdependent parts. For Darwinian evolution to be true, there must have been a series of mutations, each of which produced its own working machine that led to the complexity we can now see. The more complex and interdependent each machine's parts are shown to be, the harder it is to envision Darwin's gradual paths, Behe surveys the professional science literature and shows that it is completely hushed on the subject, obstructed by the elegance of the foundation
