Class IX: Biology Chapter 5: The fundamental unit of life. Chapter Notes Key learnings: 1) In 1665‚ Robert Hooke first discovered and named the cells. 2) Cell is the structural and functional unit of all living organisms. 3) Organisms may be unicellular or multicellular. A single cell constitutes the unicellular organism whereas many cells coordinately function in case of multicellular organism. 4) The size‚ shape and volume of the cell are related to the specific function that they

Comparing Plant and Animal Cells Hypothesis: I predict I will see the following organelles when observing a plant and animal cell under a microscope: the cell membrane‚ cell wall‚ nucleus‚ and the endoplasmic reticulum. Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present

are 50S and 30S. Ribosome in eukaryotes is of 80S type‚ and the two comprising subunits are 60S and a 40S. Since the cell size in prokaryotes is relatively smaller to that of the eukaryotes‚ the organelles like mitochondria‚ golgi bodies‚ endoplasmic reticulum and chloroplast are absent in the small-sized prokaryotic cells whilst Eukaryotic cells house all these membrane bound organelles inside the cell. Cell division in prokaryotes is simple‚ and occurs by binary fission

Chapters 6‚7 &31 Question 1 1 out of 1 points Some enzymes contain molecules in the active site that help facilitate chemical transformations. These molecules are called: Selected Answer: coenzymes. Correct Answer: coenzymes. Question 2 1 out of 1 points People with high cholesterol levels often take drugs in an attempt to lower their cholesterol levels. One such drug is Lipitor. How does this drug work? Selected Answer: It acts as a competitive

membranes that is so long it accounts for more than half of the total membrane that is found in the cell. I’m also divided into two distinct sections of the ER that differs in the structure and function. That’s right little newbie it’s the Endoplasmic Reticulum. Now listen carefully newbie the rough ER is always making its own proteins and other things so it could add it to it’s own membrane. It’s important because the portions of the ER’s membrane its pinched off so it can form a seal sacs that’s

allows chemical reactions to take place and helps materials move around the cell. It is mainly made up of water and also contains enzymes‚ salts and organelles. Ribosomes- Produce proteins and is usually found in the cytoplasm or on the rough endoplasmic reticulum. Cell membrane- It protects the interior of the cell by controlling what goes in out of the cell. Golgi apparatus – Collects simple molecules to combine them together

there is also a lot of restaurants. These restaurants give us food to refill and give us energy to continue our visit. This could be our endoplasmic reticulum because this organelle makes lipids and gives us proteins. Inside the restaurants are chefs‚ which make our food to eat are just like ribosomes which makes proteins for us inside the endoplasmic reticulum. After all this eating and refueling for the body you need a place to throw away your trash like a
