Resource summary

Cell Structure
  1. Cell Membrane
    1. Semipermeable-controls entry and exit of specific materials.
      1. Keeps cell contents together allowing efficient coordination of its activity
      2. Cytoplasm-• A complex solution in which the cell’s organelles are suspended.
        1. •About 90% water.
          1. Many biochemical processes take place here
          2. Nucleus
            1. •The genes are present in the DNA
              1. •Controls the cell’s structure and metabolism.
              2. Chloroplast -structure conatining green pigment chlorophyll
                1. Photosynthesis
                  1. Storage of starch
                    1. • Storage of water, food (sugar, amino acids), ions, wastes.
                      1. • Role in cell elongation during plant growth.
                      2. Cell Wall
                        1. Composed of cellulose.
                          1. •Permeable to water and solutes
                            1. Protects and supports plant cells.
                              1. Prevents plant cells bursting in more dilute solutions.
