Biology

• a process in which organisms exchange different gases with the environment is called
• plants obtain gases they need through


  leaves
• oxygen is require for

  respiration
• carbon dioxide is need for

  photosynthesis
• in gas exchange in aquatic plants what lilypads use?

  leaves that float
• Mangroves use what in gas exchange

  pneumatophores
• submerged aquatic plants use____ in gas exchange

  epidermis
• The earthworms use this in their gas exchange

  skin
• fishes use this un their gas exchange

  gills
• terrestial arthopods use blank in their gas exchange

  spiracles
• this is the tiny air tubes that found in spiracles

  trachea
• birds use this in gas exchange

  air-sacs
• terrestial vertebrates use what in their gas exchange

  lungs
• amphibians use their moist blank in gas exchange


  skin
• reptiles use what in gas exchange 

  folded lungs
• mammals use what in their gas exchange

  alveoli
• Inspiration is breathing


  in
• Expiration is breathing 


  out
• it contracts and flattens to create a partial vacuum in the lungs when breathing

  diaphragm
• this is the organ system that involves inhaling of oxygen and exhaling carbon dioxide to meet the energy requirements

  human resoiratory system
• through what water and minerals can enter the plants

  pipe-like vessels
• Top to bottom transportation of water molecules in one direction

  xylem
• necessity of food molecules

  phloem
• it is the organ used to transport nutrients and gas body

  circulatory system
• the blood is not enclosed in blood vessel but pumped into an open cavity called homocel and is called hemolymph 


  Open circulatory system
• closed loop system, the blood is not free cavity, blood is contained inside blood vessels

  closed circulatory system
• it is the open cavity

  homocel
• mixed intervitial tissue


  hemolymph
• it pumps blood


  heart
• it carry oxygen high blood


  arteries
• it carry deoxygenated blood

  veins
• neearly everything transport media

  blood
• a mechanism by which food is taken in, and converted into the energy and other essential nutrients

  nutrition
• organisms that prepare their own food through the process of photosynthesis

  Atotrophic
• Organisms that can not make their own food and depends on autrotrophs

  Heterotrophic
• organisms obtain nutrient from dead organic matter


  saprophytic
• organisms takes food from another organisms, parasite-host


  parasitic
• this is the essential substances

  nutrients
• large amount if it is required in our body


  macronutrients
• it required smaller trace amount in our body

  micronutrients
