In a diagram of a cell of a LEAF of a sycamore tree it has a cell membrane, cytoplasm, a nucleus, chloroplast and a cell wall. Name the part which is present in this cell but would not be present in a ROOT cell from a sycamore tree.
Why is Chloroplast not present in a cell of a root cell?
No photosynthesis takes place in roots
What part of the cell helps keep cell shape?
What part of the cell controls the entry and exit of substances?
What contains the genetic material that controls the cell's activities?
Where do many chemical reactions take place?
Which part of the cell is the site of the trapping of light for photosynthesis?
