§4.3

REQUIREMENTS FOR LIFE

§4.3: LEARNING GOALS

• I can list the differences and similarities between how plants and animals regulate the gasses carbon dioxide and oxygen.
• I can list the differences and similarities of the transport systems in plants and animals.
• I can list the differences and similarities between how plants and animals excrete their waste products.
• I can list the differences and similarities between how plants and animals gather information about their surroundings.
• I can list the differences and similarities between how plants and animals reproduce.

§4.3: KEY WORDS

• photosynthesis
• breathing
• xylem
• phloem
• heart
• blood vessels
• liver
• kidneys
• pollen
• egg cells
• sperm cells

§4.2: MRS GREN

• Movement: moves with a part of itself or its entire body
• Respiration: turns food into energy
• Sensitivity: reacts to changes of its environment
• Growth: gets bigger
• Reproduction: can produce more individuals of the same species
• Excretion: produces waste products and removes those
• Nutrition: produces food or takes in food

Plants

• Take up/release gasses through openings in their leaves called STOMATA
• Stomata open and close
• Water and other nutrients come from the soil via ROOTS

Animals

• Take up/release gasses through a breathing system.  
• This is different in different animals. Examples are Lungs and gills
• Water and other nutrients come from food

NUTRIENT INTAKE

Plants

• One tube brings water up from the soil to the leaves
• Another tube brings glucose and oxygen down from the leaves to the rest of the plant

Animals

Most animals use a blood transport system:

• Pump  (= heart) 
• A network of tubes (= vessels)
• Fluid (= blood)

TRANSPORT

Plants

• Stomata release waste gasses

• Other products are put in old leaves that fall off the plant

Animals

• Breathing system releases waste gasses

• Kidneys produce urine

• Liver filters other waste which leaves the body through faeces

EXCRETION

Plants

• Move to face the sun

• Sense gravity so their roots can grow down

Animals

• Have senses to react to their environment

• This is different depending on the animal

SENSITIVITY

Plants

• Flowers are used for reproduction
• Animals spread pollen for plants so they can reproduce
• Some plants reproduce by cloning themselves.

Animals

• Male reproductive cells: Sperm cells
• Female reproductive cells: Egg cells
• Fertilization happens when the sperm + egg fuse together.

REPRODUCTION

Short break (5 min)

• Do not move from your seat
• Keep your volume down!

Lab journal general feedback

Overall well done!

Some general points of improvement:

• Be complete, points were lost because of missing worksheets (or parts)
• Text or answers are short or incomplete
•  Research questions have a question mark (?)!
• Observations are not conclusions, it is something you notice during the experiment (like, the finger felt tired after 40 seconds)

Lab journal general feedback

The grades will soon be in magister (wage should be changed to 1x instead of 2x). 

Now take a look at your own lab journal and if you have questions please ask them to me! 

Homework

• Complete  all the exercises of §4.3
• Study the glossary of §4.1, elements, §4.2 and §4.3
