,cell wall - ANSWER >>>>>surrounds cell membrane in
plants; rigid
cell membrane - ANSWER >>>>>A cell structure that
controls which substances can enter or leave the cell.
nucleus - ANSWER >>>>>contains the cell's DNA
ribosomes - ANSWER >>>>>involved in protein synthesis
chloroplast - ANSWER >>>>>Site of photosynthesis;
contains chlorophyll

changing
describe the polar and non polar regions of the
phospholipid layer - ANSWER >>>>>polar heads are
hydrophilic "water loving"
non polar tails are hydrophobic "water fearing"
why is the cell membrane considered to be a bilipid layer -
ANSWER >>>>>it is made of two layers of phospholipids

things
What will not go across the cell membrane - ANSWER
>>>>>large molecules such as proteins do not move through
the membrane on their own
