Microscope and basic cell
The type of microscope that uses light and lenses to create a magnified image of a specimen.
What is a light microscope?
Term describing the cell membrane's ability to allow only select substances in and out.
What is selectively permeable?
The organelle that acts as the cell's control center because it contains DNA.
What is the nucleus?
cheek cell was used
What type of animal cell was used in the experiment?
Simple, single-celled organisms such as bacteria that lack a nucleus or membrane-bound organelles.
What are prokaryotes (or prokaryotic cells)?
Cell wall, Nucleus, Cytoplasm, Cell membrane, seen under a light microscope
What are microstructures?
The double-layer structure formed by lipids that forms the core of the cell membrane
What is a phospholipid bilayer?
Thread-like structures of DNA and protein in the nucleus that carry genes
What are chromosomes?
It was used to stain the cell wall and nucleus in the plant cell for viewing under the microscope.
Why was iodine solution used?
Organisms like plants, animals, fungi, and protists whose cells contain a nucleus and membrane-bound organelles
What are eukaryotes (or eukaryotic cells)?
Uses beams of electrons to magnify and visualise objects - high resolution
What does a electron microscope do?
Unlike the selectively permeable cell membrane, the plant cell wall possesses this level of permeability.
What is fully permeable?
Openings in the double nuclear membrane that allow molecules to pass into and out of the nucleus
What are nuclear pores?
Supplies energy to the cell and is site of respiration
What is the function of the mitochondria?
A network of membranes without ribosomes and makes lipids
What is the smooth endoplasmic reticulum (ER)
A lens used to magnify the image
What is the objective lens?
Organisms like amoebas, bacteria, and yeast that consist of only a single cell carrying out all life functions.
What are unicellular organisms?
Has openings and allows molecules in and out, also is double.
What is a nuclear membrane?
The liquid part of the cytoplasm
What is the cytosol?
A network of membrane-bound sacs covered in ribosomes that makes and transports proteins.
What is the Rough Endoplasmic Reticulum (Rough ER)?
Eyepiece lens X Objective lens
How to calculate 'Total Magnification'
These molecules are scattered throughout the cell membrane bilayer to serve as channels, transporters, or receptors
What are proteins?
The dense, dark region inside the nucleus responsible for producing ribosomes.
What is the nucleolus?
Site of photosynthesis, containing a green pigment called chlorophyll
What are chloroplasts?
Organelle consisting of unconnected membrane sacs called cisternae that processes, sorts, and packages molecules into vesicles
What is the Golgi apparatus?
