Flowering Plants Flashcards
Root
Anchor and support the plant in the soil
Take in or absorb water and minerals
Some plants (eg yams ) store food in there roots
Stem
Support to hold up leaves and flowers
Transport water from the roots to the leaves and also transport food from the leaves to the roots
Some stems store food ( eg lettuce and cabbage)
Leaves
Make food using photosynthesis
Allows gases and water vapour to pass in and out
Some leaves store food (eg lettuce and cabbage)
Fruit
Protect seeds
Provide for for seeds
Bud
Allows new leaves and flowers to growv
Xylem
Transports minerals and water from the plant
Phloem ( f for phloem ,f for food)
Transports food from the leaves
Transportation
Is the loss of water vapour from the stomata of the leaves
It provides water to the leaves for photosynthesis
Helps cool pant down ( like sweating )
Stoma
Stoma are title holes underside of a leaf
Transpiration stream
The flow of water from the roots up through the plant and the leaves is called the transpiration stream
Photosynthesis
Theprosses were plants are made green
Why are levee and plants green
Because contain chlorophyll with is a green chemical needed for photosynthesis
Chlorophyll
Is found in chloroplasts in plant cells, made in plants mostly found in leaves absorbs light photosynthesis can take place
What parts contain chlorophyll
Any green part of a plant has chlorophyll
Photosynthesis word equation
Carbon dioxide + water + ( sunlight and chlorophyll) -> glucose + oxygen
Factors needed
Carbon dioxide; passes into leaves through stomata
Water: from soil enters trough roots
light:from sun absorbed by leaves due to there large flat surface provides energy needed to form food
Products
Glucoses: made by plant to provide energy in respiration to form starch in parts of the plant and form cellulose
Oxygen: gas made by photosynthesis used for respiration to provide energy in the leaf released from leaf in the air
Plant responses
Tropism: the change in growth of a plant in response to an outside stimulation
Phototropism: how plants can change in different lights
Geotropism : how a plant can change responding to gravity
This allows to store as much minerals as possible
Respiration
Controlled release of energy from food not the same as breathing
Two types (aerobic respiration- requires oxygen) ( anaerobic- doesn’t require oxygen)
Factors of respiration
Glucoses comes from food ,oxygen comes from air
Products of respiration
We breath out carbon dioxide and water vapour
We uses energy on a daily walking talking thinking
Anaerobic respiration
Is the human mussel products lactose acid with causes our mussel to cramp
Fermentation
Prouduces the fermentation of foods eg beer made from yeast feeding of glucoses
Parts of flower
Petals are used to attract insects into the flower may have guidelines and be scented
The sepal : may be green protect flower offen bright colour to attract insects
