What is the name of the process by which cells become specialized for a particular function from stem cells - differentiation
Explain what tissues are - a collection of specialized cells
Explain what an organ is - a collection of tissues performing specific physiological functions
what is the difference between to ribosomes in a prokaryote and a eukaryotic cell - prokaryotes - 70s ribosome
eukaryote - 80s ribosome
Describe the function of the nucleolus - Produces ribosomes and RNA
Describe the function of the cell wall - Provides rigidity and protection to the cell
Describe the function of the chloroplasts - Site of photosynthesis as they contain chlorophyll
Describe the function of the plasmodesmata - A channel through the cell wall the allows transport of materials from one cell to another
Describe the function of the amyloplasts - Stores starch and converts starch back into glucose when the plant needs energy
Describe the function of the vacuole - Stores water and chemicals for cell use. Also maintains turgor of cell
Describe the function of the tonoplasts - Membrane the surrounds the vacuole. Protects the vacuole, isolates it from harmful substances and controls water flow in and out of the vacuole
Why are gram positive bacteria more susceptible to antibiotics? - Permeable cell wall whereas gram negative bacteria have a semi-permeable cell wall
Describe the adaptations found in a palisade cell - Closely packed together
Chloroplasts
Large vacuole
Explain why the palisade cell has a large number of chloroplasts - To absorb lots of light for photosynthesis
Explain why palisade cells are closely packed together - To form a continuous layer in the leaf
Explain why palisade cells have a large vacuole - To maintain turgor (pushes against the cell wall to maintain rigid shape)
