what is a nucleus?
Contains DNA and its controls the cell.
what does the ribosomes do?
its where protein is made.
what does the mitochondria do?
releases energy by respiration
what happens in the cytoplasm?

contains chlorophyll which absorbs light for photosynthesis
what is in the vacuole?
contains cell sap
what does the cell membrane do?
it controls what enters and exits the cell
what is the cell wall?
a supportive outer layer for the cell to help it from bursting
what is a specialised cell?

what make up Protoctista since it is a unicellular cell.
Eukaryotic organisms and a nucleus.
name 5 parts of a bacteria.
cell wall, cell membrane, DNA, ribosomes, cytoplasm, flagellum.
why is a virus not considered living?
because they don’t complete all the seven life processes: movement, respiration, sensitivity, growth, reproduction, excretion and nutrition (MRS GREN)

it doesn’t have one
What nutrition does the bacteria kingdom have?
saprotrophic
