what are the three points to the cell theory
what do compound light microscopes look at
A compound microscope uses two or more lenses to produce a magnified image of an object, known as a specimen, placed on a slide (a piece of glass) at the base.
What does the vacuole do? and how is it diffrent in plants vs animals cells
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane.
What do scanning electron microscopes look at
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons
What is a ribosome?
A structure upon which proteins are assembled
What is a theory?
A theory is a statement that has not been tested
what do dissecting microscopes look at
Dissecting and compound light microscopes are both optical microscopes that use visible light to create an image
what are the pumps called
Primary active transport, also called direct active transport, directly uses metabolic energy to transport molecules across a membrane
What are the 2 types of cells?
Prokaryotic and Eukaryotic
What do chloroplasts do?
This is where photosynthesis occurs. They contain a green substance called chlorophyll.
What is a scientific law?
a concise statement that summarizes the results of many observations and experiments
What is an organelle?
any of a number of organized or specialized structures within a living cell.
What do lysosomes do?
break down macromolecules, highly acidic inside (5 PH)
Which one of the 2 is a plant cell?
eukaryotic
Which one of the 2 is an animal cell?
eurokroytic
ATP is a type of energy used by cells. What organelle makes this?
mitochondria
Does it require energy?
no
Which one of the 2 is a bacteria cell?
prokroytic
What is the nucleus?
protons and neutrons
What is active transport?
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
What is the function of the cell membrane?
to control what enters and leaves the cell
What does Golgi do
1) Manufactures polysaccharides from simple sugars and modifies the carbohydrate tags on proteins or lipids. Some proteins are packaged into secretory vesicles to be released from the cell via exocytosis. 2) Makes lysosomes.
How are proteins made?
By joining amino acids into long chains called polypeptides
What is the cell membrane?
Holds the cell together and controls what goes in and out
What does Smooth and Rough ER do
Image result for What does Smooth and Rough ER do biologywise.com Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. ... Smooth ER (SER) acts as a storage organelle.
What is facilitated diffusion?
Movement of specific molecules across cell membranes through protein channels
What is diffusion?
The movement of particles from an area of high concentration to an area of low concentration.
What is osmosis?
diffusion of water
What are the 2 main differences between the prokaryotic and eukaryotic cells
plant cells have chloroplast and cell wall
whats the function of the ribosome
site of protein synthesis
