What isnt found in animal cells?
Vacuoles
Carbohydrates
Plasma Membrane
Lipids
What do all cells have in common?
Cell Membrane
Cell Wall
Ribosome
Glucose
Prokaryotic Cells have a nucleus
What do eukaryotic cells contain?
Nucleus, Cell membrane, cytoplasm
Nucleus Cell Wall Cytoplasm
Ribosome Cell wall Cell Membrane
What do Prokaryotic cells have?
Bacteria
Cats
What is the cytoplasm
Includes the fluid within the cell and genetic material
Contains heat within the cell
Contains only DNA
Which of the 4 have a cell wall?
Plants, Bacteria, Fungi, Algae
Plants, Algae, Water, Bacteria
Bacteria, Water, Algae, Heat
What do cells walls exchange?
Gas and Water
Heat and Water
Cells and DNA
Cellulose
What are plants made of?
Ribosomes
Cholorplast
DNA is the information of the cell which is the nucleus.
Chromatin does what?
DNA bound to make only protein
DNA bound to make only cells
DNA bound to make only organelles
Chromosomes is DNA condensed during cell divison
What do the nucleolus and the nuclear envelope do?
Nucleolus make ribosomes and has a nuclear envelope have 2 layers with pores that allow for the passage of material with RNA to go out
Nuclelous make ribosomes and nuclear envelope have 1 layer with pores so it allows for passage of material with RNA to go out.
Nucleolus makes cells and nuclear envelopes have no layers
Cytoskeletons maintains cell shape and network of protein filament
What are organelles?
Specialized structures within the cytoplasm who perform specific roles.
Specialized structures within the nucleus who perform specific roles.
Endoplasmic reticulum have 2 types which are
Rough er are covered in Smooth ER are synthesis of
Ribosome use and found free in cytoplasm and ER
Ribosomes are found free in where?
Nucleolus
Cytoplasm and ER
Cell wall
Golgi apparatus construct lysonomes and use ❌
Lysonomes break things down into smaller molecules
Flagella are the tail for moving and every cell has one.
Vacuoles are the storage of what?
Waters Salts Proteins Carbs
Gas Salt Sugar Carbs
Proteins Carbs Lipids
Water and Protein
What does the mitochondria (Powerhouse) What does it do and what does it contain
Take food create energy for the cell
Has 2 membranes and contains their own DNA
Takes food creates energy for the cell
Has 2 membrane and doesnt contain DNA
Phospholipids are fats with phosophorus
Phosopholipids are the wall
What is true about the Fluid Mosaic Model
Proteins act as the doors, cells are easy to get in, cells need a nametag and have hydrophobic cells meaning scared of water.
Proteins acts as the doors cells are not easy to get in cells need a nametag and are hydrophobic
Proteins dont do anything
Cholosterol is good for the cell and keeps from from becoming a solid.
Phospholipids have a double layer with tails facing each other and heads on both the inside and outside of the cell.
Plasmids are made of what?
DNA
What is true about Passive transport
it moves molecule without extra energy
it moves molecules without energy
it moves molecule with plenty of extra energy
are moving molecules with extra energy
Diffusion is the movement of molecules from areas of low to high concentration has extra energy and is passive
What is true about molecules
they are claustrophobic
they are small and non claustrophobic
They are claustrophobic and run to equilibrium
Osmosis is
diffusion of water across membrane. selects which things get through
diffusion of water across membrane does not select which things get through.
Diffusion of cells selects which things get through
❌ is 5% salt and 3% salt in the cell and is of high concentration of dissolved particles.
❌ is 2% salt and 5 % salt in the cell and is low concentration of dissolved particles.
❌ can go anywhere
when a cell is in a hypotonic solution it's going to suck to water and if you add more water it will become diluted. They will eventually explode and will create LYSE.
When a cell is in a hypertonic solution....
water can move and water will always flow to the bigger number
water can move and always will flow to the smaller number
water cant move and will always flow to bigger number
cells just sneak in
❌ is a way to take in large food items in pouches which is a form of endocytosis
Endocytosis create pouches to move large items into a cell
What did anton van leewenhoek discover
microscope and was the first to see life in water
plants
cells
Matthias schleiden said ❌ and we cant prove him wrong
Theodor schwann said all animals arent made of cells
❌n 1855 said all cells come from existing cells.
all eukaryotic cells have organelles with animal plant fungi cells. While prokaryotic has a cell membrane and a cytoplasm with bacteria
Diffrence between animal and plant cells?
Animal cell doesnt have a cell wall and plant cells dont have a lysosome Animal cells dont have chloroplast while plant cells have cholorplast
animal cells do have a cell wall and plant cell have a lyosome
Animal cells have a cell wall and plant cells dont have a cell wall
Cells Tissues Organ Organ System Organism
are a group of similar cells that perform a particular function.
are groups of tissues working toghether
❌ are a group of working organs to perform specific function
What is true about unicellular organisms?
includes prokaryotes and eukaryotes
algae yeast fungi bacteria
simple cells are unicellular
includes prokaryotes and eukaryotes including ribosomes
algae yeast fungi bacteria water
simple cells are not unicellular
are jobs for each type of cell
All cells have DNA Cell Membrane Cytoplasm
What is the organelle that act like a post office?
golgi body
ribosome
ER
❌ helps move molecules around the inside of the cell
