Cells Flashcards
What is the nucleolus and do both have it
Both have it
Makes ribosomes
Ribosomes make protein
What does a Nucleus do and do both animals and plant cells have it
Most obvious organelle
Where all genetic material is stored (DNA and RNA)
Control centre
Both plant and animal cells have it
What is cytosol and do both have it
Both
Soup inside cell
Only part of cytoplasm that is not an organelle
What is cytoplasm
It is a collective term for the cytosol plus organelles
What is centriole and is it both
Animal cells only
Part of centrosone
Active during cell division
What is the Golgi and is it both
It is both
Is a membrane bound structure
Is important in packaging macromolecules for transportation either inside or outside the cell
What does the lysosome do and is it in both
Both
A big bubble full of hydrolytic enzymes that hunts and destroys what needs to be destroyed
What is s cell membrane and is in both
Both Every cell is enclosed in a membrane A double layer of phospholipids Is selectively permeable Inside-hydrophilic Outside-hydrophobic
What is a mitochondria and is it in both
Both
uses oxygen to create energy
Has a double membrane
What is a Vacuole and is it both
Both
Plays role in intercellular digestion and cellular waste products
In animal cells they tend to be small
In plants they tend to be large and play several different roles
Storing nutrients and waste products, helping increase cell size during growth,also it regulates turger pressure
Smooth Endoplasmic Reticulum
Both
Makes lipids and horamones
In liver breaks down lipids
Rough Endoplasmic Reticulum
Both
Makes protein
Ribosomes
Both
Makes proteins
Reason rough Endoplasmic reticulum is rough because has ribosomes spotted all over it
Cell Wall
Plants only
A protective cell wall made up of polysaccharide
In higher plant cells the polysaccharide is usually cellulosel
Fluid collects in the vacuole and presses against the cell wall this is reason for crispness of fresh vegetables
Chloroplast
Plants only
Are specialized organelles that are found in higher plant cells
These organelles contain the cells chlorophyll which is responsible for the green colour on the leaves witch is necessary to be able to absorb energy from sunlight
