False, organelle doesn't have a function
Alll organelles are found in all cells
True
False, not all organelles are found in all cells
False, all organelles are found in eukaryotic cell
False, all organelles are found in prokaryotic cells.
Function of this organelle?
transport proteins
package and ship proteins
synthesize proteins
digests food and worn-out organelles
some organelles are found only in plant cells, while others are found only in animal cells.
True
False
Prokaryotic cells do have membrane-bound organelles.
True
False, they don't have membrane-bound organelles
a semi-fluid/gelatin like environment inside the plasma membrane where organelles are, and some chemical process occurs.
Nucleus
cell membrane
cytoplasm
ribosomes
select the correct sentence:
All types of cells have cell membrane
All types of cells have a cytoplasm
there are 5 types of cells
a cell consists of 5 organelles with similar function
Mention 3 organelles that are in te cytoplasm
Energy, Neurons, Heart
Neurons, Mitochondria, Ribosomes
Centriole, Nucleus, vacuole
None
Function of the cytoplasm
The function of the cytoplasm is to maintain the integrity of these genes.
The cytoplasm is help retain waste products.
The cytoplasm it is functions as a micro-machine for making proteins.
The cytoplasm is responsible for holding the components of the cell and protects them from damage.
The part of cell which occur between plasma membrane And nuclear envelope.
Nucleus
Cytoplasm
Cell wall
None
Granules made from protein and rRNA, site of protein synthesis
ribosomes
mitochondria
lysosome
endomembrane system
are short, numerous hair-like projections on the surface
Celia
flagella
nucleus
ribosomes
Cilia help in :
"select all apply"
help movement
help in cell division
feeding
sweeping substances along the surfaces
Flagella help in :
"select all apply"
help movement
help in cell division
feeding
sweeping substances along the surfaces
Nucleus are long, few projections on the surface of cells
True
False, cytoplasma are long, few projections on the surface of cells
False, ribosomes are long, few projections on the surface of cells
False, Flagella are long, few projections on the surface of cells
Cilia and flagella :
may be found in both
only found on eukaryotic
only found in prokaryotic
a cell managing structure (like the brain of the cell)
chromatin
Nucleus
lysosomes
centrioles
what does necleus contain :
DNA(chromatin)
nuclear pores
nucleolus
nuclear envelope
all of the above
store information used to make proteins for cell growth, function, and reproduction
DNA(chromatin)
nuclear pores
nucleolus
nuclear envelope
found inside of the nucleus and is responsible for making ribosomes
DNA(chromatin)
nuclear pores
nucleolus
nuclear envelope
(xx) is a membrane that covers the nucleus and is full of dots that are called (yy) which allows materials to come in and out.
xx = DNA(chromatin)
yy = nuclear pores
yy = nucleolus
xx = nuclear envelope
a nucleus is found in
only prokaryotic
only eukaryotic
both ( prokaryotic and eukaryotic )
a nucleus is found in
only prokaryotic
only eukaryotic
both ( prokaryotic and eukaryotic )
cell wall is a thick, rigid layer of fibers that surrounds the outside of the plasma membrane, protects the cell and gives it support
True
False, its cell membrane
False, its nuclei
Cell walls are found in :
select all apply
Plant cell
Fungi cell
eukaryotic cell
prokaryotic cell
(xx)= membrane is flexible , components ( proteins, phospholipids) can float around from one side of the membrane to the other
Fluids
Mosaic
(xx)= membrane is made of many small parts, when the parts are put together, they seem like one structure
Fluids
Mosaic
Forms a barrier and makes the membrane selectively permeable
Carbohydrate chain
Transport protein
Lipid bilayer
Transport protein
Forms a barrier and makes the membrane selectively permeable
controls what enters and leaves the cell
signals other cells
Proteins have receptor proteins and transport proteins
True
False
on the outer surfaces, transmit signals into the cell
Receptor proteins
Transport proteins
span the entire membrane creating a channel for substances to enter and leave the cell: helping with selective permeability
Receptor proteins
Transport proteins
Carbohydrates :
Forms a barrier and makes the membrane selectively permeable
function to identify chemical signals and help in cell recognition
turn in facing away from the watery environment
The ( x x ) of the phospholipid bilayer faces the watery environment inside and outside the cell
( x x ) = hydrophilic heads
( x x ) = hydrophobic tails
The ( x x ) turn in facing away from the watery environments
( x x ) = hydrophilic heads
( x x ) = hydrophobic tails
The membrane is composed of a phospholipid bilayer - two layers of phospholipids.
Each phospholipid is made up of :
2 correct answers
2 non-polar phosphate head that is attracted to water or hydrophilic ("water loving")
2 non-polar fatty acid tails that are repelled by water it hydrophobic ("Water fearing")
A polar phosphate fatty acid tails that are repelled by water it hydrophobic ("Water fearing")
A polar phosphate head that is attracted to water or hydrophilic ("water loving")
Select the false statements :
A phospholipid bilayer is A barrier is created that is polar on the surfaces and nonpolar in the middle, controlling what can easily enter and exit the cell
The phosphate heads face the inside and outside of the cell, the lipid tails are in the middle.
A polar phosphate fatty acid tails that are repelled by water it hydrophobic ("Water fearing")
A polar phosphate head that is attracted to water or hydrophilic ("water loving")
Most of the molecules in the plasma membrane are
lipids(fats)
DNA
proteins
genetics
functions of plasma membrane :
"Select all that apply"
allows nutrients to enter and wastes to leave the cell
controls what enters and exits a cell
helps maintain the cells homeostasis (maintain balance in an organism's internal environment )
is a selectively permeable - selects what permeates (sprwades throughout ) some substances are allowed to cross, other are kept out
all of the above
