Unit 5-6 Test Flashcards
Who discovers microorganism?
Leuevenhook
Who concluded all plants were made of cells?
Schleide
Who concluded that all animals were made out of cells?
Schwann
Who stated hat new cells could only be produced front the divisor if existing cells?
Virchow
What is the cell theory?
All living things are composed of cells
Cells are the basic unit of structure and function of living things
New cells are produced from prexsisting cells
What are some important characteristics of cells?
All have a cell membrane
Some pint in their lives they contain DNA
What are prokaryotes?
All single called
No nucleus for DNA
They are simple
What are plasmids?
A structure that can replicate
What are eukaryotes?
Mostly multicellular some single
Have nucleus
Complex
Membrane bound organelles
How are prokaryotes and eukaryotes similar?
All have a cell membrane
All have DNA
All have ribosomes
Who named cells?
Robert Hooke
What is the job of the nucleus?
The boss/ CEO of the cell
What is the use of cytoplasm?
“Work environment”
What roll do the organelles play?
The workers
What holds genetic material l?
Nucleus
Where do ribosomes come from?
The nucleus
What do robosomes do?
Assemble proteins
What does ER stand for?
Endoplasmic reticulum
What does the ER do
Assembles lipid proteins and other materials
What differences to the rough and smooth ER have?
Rough ER has ribosomes attached
Smooth ER does not
What is the Golgi apparatus l?
Post office
Modifies,sorts, and packages proteins
What does the lysosome do?
Garbage man
Digest or breaks down lipids,carbs,proteins, even organelle using enzymes
Only found on animal cells
What are vacuoles and what do they do?
The storage facility
Hold water,salt,proteins, and carbs
What are mitochondrial and what do they do?
The power plant
Converts chemical energy from food (glucose- 6ch12o6) into usable energy (ATP)
What are chloroplasts and what do they do ?
The solar panels
Capture light energy from the sun and convert into chemical energy (photosynthesis)
What is the cytoskeleton and what does it do?
Support beams
Maintain cell shape
What is the cell membrane and what does it do?
Broader control
Controls what enters and leaves the cell
Made up of proteins and lipids
What is the cell wall and what does it do l?
The cell she’ll
Provides support and protection
Only implants
What is diffusion?
When the solute moves from high to low concentration
What is facilitated diffusion?
A channel issued with passive transport of it goes straight through the membrane
What is osmosi
The diffusion of water
What are concentration levels?
Hyper tonic
Isotonic
Hypotonic
What is a hypertonic solution?
High levels of dissolved solute
What is an isotonic solution?
Equal levels of solute in both solution
What is a hypotonic solution?
Low levels of dissolved solute
What is osmotic pressure
Maintain so that cells don’t explode or shrivel
What is active transport?
Requires energy
Pumps molecules against their concentration gradient
What is endocytosis?
Unfolding if the membrane to bring things inside the cell
What is exocytosis?
Out folding of the membrane to remove objects from cell
How do cells move?
Flagella and cilia
