Plants Flashcards
What do producers do
Make their own food
Name 2 producers
Plants
Algae
Where do Algae live
In the water
What do Algae not have
Leaves
Root
Stem
What are consumers
Animals that have to eat other organisms to survive
What do we call the process where producers make food
Photosynthesis
Give the word equation for photosynthesis
Carbon dioxide + Water->Glucose + Oxygen
Where does the energy for photosynthesis come from
Light
Which part of a leaf cell carries out photosynthesis
Chloroplasts
What makes chloroplasts green
Chlorophyll
Where does water enter the plant
Throught the root hair cells
What transports water through a plant
Xylem tubes
How does Carbon Dioxide enter a leaf
Through tiny holes in the leaf
How does a leaf being thin help Photosynthesis
It allows gases to diffuse in and out easily
What do phloem tubes do
Transport glucose
What is the function of the waxy
layer on a leaf
This reduces water loss by evaporation
What do we call the tiny holes in leaves
Stomata
What do guard cells do
Open and close the stomata
What is the palisade layer
The part of a leaf which contains the most chloroplasts and carries out the most photosynthesis
Where in a leaf is the palisade layer
Near the top
What is the spongy layer
The part in the leaf with air spaces
What do plants need nitrates for
Healthy growth
Making amino acids
What do plants need phosphates for
Healthy roots
What do plants need Potassium for
Healthy leaves and flowers
What do plants need magnesium for
Making chlorophyll
Which part of a plant absorbs minerals
The root hair cells
Which part of the plant carries the minerals
Xylem tubes
What are the signs of a plant having a
nitrate deficiency
Poor growth and yellow older leaves
What process uses oxygen to get the
energy out of glucose
Aerobic respiration
Give the word equation for aerobic respiration
Glucose + Oxygen->Carbon dioxide and water
What part of the cell carries out the
aerobic respiration
Mitochondria
What are the signs of a plant having a magnesium deficiency
Leaves turn yellow
What are the signs of a plant having a phosphorous deficiency
Poor root growth
Purple younger leaves
What are the signs of a plant having a potassium deficiency
Yellow leaves with dead patches
What is a mineral deficiency
Not having enough of a particular mineral (in plants)
What do farmers use to replace missing minerals in food
Fertilisers
What do NPK fertilisers contain
Nitrogen
Phosphorus
Potassium
What is chemosynthesis
Making glucose using chemicals as a source of energy
Where do sulfur bacteria live
At the bottom of the sea near volcano vents
What do sulfur bacteria do
Turn hydrogen sulfide into sulfer by chemosynthesis
Where do Nitrogen bacteria live
In the soil and in the roots of plants
What do nitrogen bacteria do
They use Nitrogen compounds for Chemosynthesis
Sulphur bacteria sometimes live in
tubeworms, benefiting both. What is
this type of relationship called
A mutualistic relationship
