A phospholipid is made of a _____________ head and a _____________ tail
hydrophilic head
hydrophobic tail
Name an organelle that is only found in animal cells.
lysosome
many small vacuoles
Cells that grow uncontrollably are called ___________________
cancer or tumor
What type of cells in the human body does mitosis divide?
It divides all body cells in the human body (like red blood cells, skin cells, hair cells) except for sperm or egg
What part of the cell membrane maintains fluidity?
cholesterol
What structure does a plant cell need when it goes through cytokinesis?
cell plate
Plant cells form a cell plate to divide the cells since they have a cell wall and a fragile cell membrane, while animal cells don't need this structure to divide because their cell membrane is able to divide without a problem.
