biology - Coggle Diagram

- - - - Movement- moving from one place to another
      - Respiration- using oxygen from the air to convert glucose to energy
      - sensitivity-the changes an organism carries out due to their external environment
      - Control- changes to the organism due to internal environment
      - Growth- increase in cell size, cell number or cell complexity
      - Reproduction- reproduction of offspring
      - Excretion- getting rid of metabolic waste
      - Nutrition- using food to turn into energy
    - - eukaryotic organisms have a nucleus, which controls the function of the cell
      - there is the animal cell. consists of:
        ribosomes
        nucleus
        cytoplasm
        cell membrane
        mitochondria
      - then there is the plant cell. it consists of:
        mitochondria
        cytoplasm
        nucleus
        permanent vacuole
        cell wall
        cell membrane
        chloroplast
        ribosomes
      - then there is a bacteria cell. it consists of:
        nucleiod
        cytoplasm
        cell membrane
        ribosomes
        capsule
        plasmids
        cell wall
        flagellum
      - fungi are eukaryotic and include mushroom and yeast.
        yeast is a unicellular fungi. most fungi are multi-cellular.
        most fungi have thread-like structures called hyphae, which are organized into mycellulem.
        fungi have cell walls made out of chitin(complex sugar).
        fungi often feed by satrotophic nutrition(they fead on dead/decaying matter)
        however, some fungi are parasites, they feed on the living. most fungi store their carbohydrates as sugar.
        Protoctista are always unicellular and some may look like animal cells, others look more like plant cells. but they all have a nucleus, some have cell walls and/or chloroplasts. some of them can photosynthesise
      - prokaryotic cells do not contain a nucleus(e.g bacteria). bacteria cells do not have a membrane-bound organelles like mitochondria, chloroplasts and they have smaller ribosomes
      - a pathogen is an organism or particle that can cause a disease.
        fungi, protoctista, bacteria and viruses all have the capability to cause diseases. such as:
        fungi-athletes foot
        proctoctista-malaria
        bacteria- pneumonia
        virus- HIV, influenza, COVID-19, tobacco mosiac virus
        
        virus do not carry out some of the key processes to be considered 'alive', which is why they are considered particles. they are smaller than bacteria and are always parasitic, and they have the ability to infect every type of living cells
