Study Notes
Life Processes
- A living thing performs all seven life processes
- These are: movement, reproduction, sensitivity, growth, respiration, excretion, and nutrition
Organs
- Organs are parts of animals or plants that perform important jobs
- They are made up of tissues
- Organs have a specific function or role
Tissues
- Tissues are groups of the same cells working together
- They perform the same job, forming organs
Cells
- Cells are the basic units of all living things and tissues
- Specialised cells have specific features that enable them to perform a particular job
- Examples of cell parts include: Cytoplasm, nucleus, cell membrane, mitochondria, chloroplasts, vacuole, cell wall
- Plant Cells: cell walls, chloroplasts, permanent vacuole; additionally xylem transports water
- Animal Cells: cytoplasm, nucleus, cell membrane, mitochondria
Organ Systems
- An organ system is a group of organs working together
- Examples include the circulatory system, digestive system, respiratory system, excretory system, nervous system and transport system
- The circulatory system carries oxygen and nutrients around the body
- The digestive system breaks down food & takes nutrients into the bloodstream (e.g. gullet, stomach, intestines)
- The respiratory system allows the exchange of gases between the blood and lungs (e.g. lungs, trachea)
- The excretory system enables the body to get rid of waste material (e.g. kidneys, bladder)
- The nervous system allows the body to sense things & react to them (e.g. brain, nerves, spinal cord)
Plant Organs
- Leaves trap sunlight to make food
- Roots hold the plant in place and take in water and other substances
- Stems carry substances around a plant
- Xylem tissues transport water up through the plants; these are special tissue types.
- Photosynthesis - the process by which a plant makes its own food.
Animal Organs
- Heart pumps blood around the body
- Liver makes and destroys substances
- Kidneys clean the blood and produce urine; the urine is then excreted
- Bladder stores urine
- Stomach breaks up food
- Small intestine breaks up food and absorbs it
- Large intestine removes water from unwanted food and stores faeces
- Brain controls the body
- Skin is the body’s largest organ; used for protection and sensing
- Lungs take in oxygen for respiration and excrete carbon dioxide
- Animal organs such as the heart, liver, kidneys, bladder, stomach, small intestine, large intestine, brain, skin, and lungs are all examples of organs that perform essential life functions.
