chloroplasts
Capture energy from the sunlight and covert it into food that contains chemical energy
What does the cromatin do when the cell prepares to divide?
It coils up into chromosomes
Organelle
Organized or specialized structures within a living cell
What are ribosomes used for?
Making proteins
Some ribosomes are ——— while others are on the ———— ————-
-free -endoplasmic reticulum
Organelle DNA
Mitochondria and Chloroplasts contain their own genetic info in the form of DNA molecules
plant cells have..
water vacuole, chloroplasts, cell wall
Nuclear pores are...
holes that allow things to go through the envelope
Name three different types of microscopes
-Transmission microscope -Scanning microscope(3D) -Light microscope
The nucleus is the... and it...
Control center of the cell and it processes and contains DNA in the form of a Chromotin
chloroplasts
Capture anger from the sunlight and covert it into food that contains chemical energy
Nucleolus
Found inside the nucleus and produces ribosomes
What did Rudolf Virchow discover?
New cells are only produced from living cells
hydrophilic is...
water loving
Chemical reactions take place where?
The surface of the inner membrane
Prokaryote is..
Bacteria
What is the cell theory?
-the theory that all living things are composed or made of cells -cells are the basic unit of life -new cells are only produced from living cells
Chromatin is the...
Structure that DNA is in
hydrophobic is..
Water fearing
Eurkaryote
organized membrane bound organelles, with a nucleus
Animal cells don't have...
cell walls
Prokaryote
unicellular organism lacking a nucleus and not membrane bound
DNA
A complex molecule containing the genetic information that makes up the chromosomes.
Plants and animal cells are
Eukaryotic
cell membrane is made of..
phospholipid bilayer
the vesical is used for
storage or transport
What did Matthias Schleiden conclude?
All plants are made of cells
Nucleus envelope
protects the nucleus
The mitrochindria is the...
powerhouse of the cell
What type of microscope did Robert Hook invent, what did he name, and why?
-A compound microscope -Cork tissue reminded him of cells and he named cells, cells.
2 cellular boundaries are...
cell wall and cell membrane
Where is the cell wall found? What does it do?
-outside the cell membrane -It provides support and protection for the cell
plant cell vacuole
one large central vacuole; absorbs water and keeps the plant upright
The cell membrane does what two things?
-Controls what goes in and out of a cell -Communicates with other cells
All cells have what 4 things?
DNA, cell membrane, ribosomes, cytoplasm
How many protein subunits do ribosomes have?
2
Lysosome function
digestion of unneeded material
what are 2 things microtubules do and what are they?
-maintain cell shape -help divide cells -hollow tubes made of protein
What is a light microscope?
A microscope that uses a series of glass lenses and visible light to magnify an image. This microscope magnifies images up to 1,000 times the actual size.
What did Theodore Schwann conclude?
All animals are made of cells
Nucleolus function
Makes ribosomes
What resolution did the new and improved microscope have? What did it show and focus on? Aron Van Leevwenhoek
-it had a 200X resolution -It could see cells that were alive such as blood cells and microscopic organisms
What are three types of an electron microscope?
-transmission -light -scanning
cytoskeleton structure and function
-structure: network of micrfilament and microtubules (both made of protein) -helps maintain cell shape -involved in cell movement
What is a scanning microscope? meaning... What does it show?
The surface in 3D
Mitrochindria and chloroplasts are different because..
they contain their own genetic info in the form of DNA molecules
micrograph
photo taken through a microscope
What do most microscopes do?
They use lenses to magnify the image of an object by focusing light or electrons
What is a transmission microscope? meaning... What does it show?
Internal
Lipids
Detoxification
