Flowering Plants Flashcards

1
Q

Root

A

Anchor and support the plant in the soil
Take in or absorb water and minerals
Some plants (eg yams ) store food in there roots

Q

Stem

A

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)

Q

Leaves

A

Make food using photosynthesis
Allows gases and water vapour to pass in and out
Some leaves store food (eg lettuce and cabbage)

Q

Transportation

A

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 )

Q

Chlorophyll

A

Is found in chloroplasts in plant cells, made in plants mostly found in leaves absorbs light photosynthesis can take place

16
Q

Factors needed

A

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

17
Q

Products

A

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

18
Q

Plant responses

A

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

19
Q

Respiration

A

Controlled release of energy from food not the same as breathing
Two types (aerobic respiration- requires oxygen) ( anaerobic- doesn’t require oxygen)

20
Q

Factors of respiration

A

Glucoses comes from food ,oxygen comes from air

21
Q

Products of respiration

A

We breath out carbon dioxide and water vapour
We uses energy on a daily walking talking thinking

22
Q

Anaerobic respiration

A

Is the human mussel products lactose acid with causes our mussel to cramp

23
Q

Fermentation

A

Prouduces the fermentation of foods eg beer made from yeast feeding of glucoses

24
Q

Parts of flower

A

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

25
The stamen
Produces male sex cell
26
Carpel
Female sex cell
27
Life cycle of a plant
Pollination is the transfer of a male part to a femal part of the flower Insect pollination: insects rub against the sticky stigma d the pollen can end up on a carpull of another plant Wind can blow pollen from one plant to another Self pollination: when male and female flowers ripe at the same time and pollen can fall on the sticky stigma
28
Fertilisation
The union of nucleus of the pollen grain with the nucleus of the egg
29
Fruit and sead development
After fertilisation the egg develops into the seed parent plant provides the growth
30
Seed
The seed is provided its energy and raw materials to enable it to become established after dispersal,providing the environment is suitable
31
Testa
The tough outer covering
32
Radicle
The part browning down out of seed grows to form root
33
Plumule
The part growing up this growing forms the shoot
34
Food supply for seeds
The inside of the seed consists of sources of food
35
Dispersal of fruit and seeds
Dispersal: * Wind * Insects * Self Example: Dandelion Strawberry Peas ( they pop)
36
Germination
* Is the resumption of growth after a period of dormancy * mosture oxygen and heat are necessary for germination
37
Asexuals reproduction
Formation of a new individual from the cells of one parent eg strawberry grass onion potatoes daffodils
