Eukaryotic cells have a nucleus and include animal and plant cells.
Cell membrane controls the __________ of ____________ into and out of a cell.
Cell membrane controls the movement of substances into and out of a cell.
__________ is a jelly like substance where __________ take place inside a cell.
Cytoplasm is a jelly like substance where reactions take place inside a cell.
Respiration releases _______ and takes place inside ______________ in cells.
Respiration releases energy and takes place inside mitochondria in cells.
Proteins are made inside ___________ in cells.
Proteins are made inside ribosomes in cells.
Cell ______ are made of cellulose and give a cell __________.
Cell walls are made of cellulose and give a cell structure.
A ________ stores cell sap and gives a cell structure.
A vacuole stores cell sap and gives a cell structure.
Chloroplasts contain ____________ used for _______________.
Chloroplasts contain chlorophyll used for photosynthesis.
___________ absorbs light for photosynthesis.
Chlorophyll absorbs light for photosynthesis.
Genetic material is stored on _______________ held in the _______ of a cell.
Genetic material is stored on chromosomes held in the nucleus of a cell.
____________ cells, bacteria cells, have a cell membrane and cytoplasm but no ________.
Prokaryotic cells, bacteria cells, have a cell membrane and cytoplasm but no nucleus.
define the term eukaryotic cells
eukaryotic cells contain the genetic material in an enclosed nucleus
define the term prokaryotic cells
in prokaryotic cells, the genetic material is not enclosed in a nucleus
true or false?
prokaryotic cells are bigger then eukaryotic
false
they are smaller
how is genetic material in a prokaryotic cell stored
either in a single loop of dan or in small rings called plasmids
what is the function of the nucleus
enclose genetic material
define the cytoplasm
a watery solution where chemical reactions take place (first stage of respiration)
define the cell membrane
controls the molecules that can enter and leave the cell
define mitochondria
where areboic respiration takes place
define ribosomes
site of protein synthesis
True of false?
Both plant cells and animal cells can easily change their shape
false
plant cells have a regular shape
what does cellulose do
strengthen the cell wall
what is the purpose of chloroplasts
site of photosynthesis
what is the importance of the cell sap
gives the cell structure
