Cells
  1. Cells
    1. Animal cell
      1. Organelles
      2. Plant Cell
        1. Organelles
          1. Nucleus
            1. The nucleus is the control centre in the cell. It controls all that happens inside, the Nucleus contains chromosomes which carry long threads of DNA Which contain genetic code to pass onto one generation to another and make new cells.. It controls all the chemical processes that happen in the cell
              1. Cytoplasm
                1. The cytoplasm is the jelly-like substance in the living cell. One of its major elements are the organelles it has (excluding the nucleus) like the mitochondrion, where most respiration occurs and other chemical reactions to keep the cell alive. These reactions are controlled by enzymes.
                  1. Cell membrane
                    1. The cell membrane is the selectively permeable (allowing gases and liquids to pass through; penetrable) membrane or barrier, which controls which substances can enter and exit the cell. It also gives it its shape
                      1. Mitochondria
                        1. The mitochondria is a structure in the cytoplasm where most aerobic respiration happens and glucose is turned into energy and oxygen is used
                  2. Nucleus
                    1. Cytoplasm
                      1. Cell membrane
                        1. Mitochondria
                          1. Chloroplast
                            1. The chloroplast contains a green pigment called chlorophyll . It absorbs sunlight in the process of photosynthesis
                              1. Vacuole
                                1. The long lasting vacuole or space is within the cytoplasm containing salts and sugars called cell sap. This keeps the cell firm and gives it support.
                                  1. Cell wall
                                    1. The cell wall is the outer protective layer made of cellulose of a cell which covers the thin membrane. It is also a strong container which prevents the outburst of water from the uptake of it by osmosis. different organs have dissimilar structures and chemical compositions, like of a plant, fungal or bacterial organism.
                  3. Multicelluar
                    1. A multicelluiar organism is a living thing with lots of cells. Thc cells in a multicelluar animal or plant are specialised or differnated to carry out a specific funcion. For example the task of a red blood cell is to carry oxygen around the body. It is speacialised because it has a large surface area to let oxygen pass through, it has no nucleus to let more heamaglobin inside it to join onto the oxygen
                      1. Red blood cell
                        1. Nerve cell
                          1. Sperm cell
                          2. Advantages: They are larger because they have more cells Disadvantages: they need more energy to function
                          3. Unicelluar
                            1. A unicelluar organism is a living thing with just one cell. They may be one but they are quite complex. They have special features that make them suited for their environment. For example bacterial cells which is a domain of Prokaryotic cells, has a flagellum which helps it move around like a propellor
                              1. Bacteria
                                1. To reproduce they split into two and so on
                                2. Yeast
                                  1. A unicelluar organism that is added to bread to make it rise
                                  2. Protoza
                                    1. Amobea is a type of protoza which behaves like an animal
                                  3. Advantages: they reproduce quicker because it doesn't have to find a mate, it does it by itself Disadvantages: They have a short life span if their one cell gets damaged it results in death. It has to do all its life processes by itself so it takes longer
