Flowering Plants

Question 1

Root

Answer 1

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

Question 2

Stem

Answer 2

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)

Question 3

Leaves

Answer 3

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

Question 4

Fruit

Answer 4

Protect seeds
Provide for for seeds

Question 5

Bud

Answer 5

Allows new leaves and flowers to growv

Question 6

Xylem

Answer 6

Transports minerals and water from the plant

Question 7

Phloem ( f for phloem ,f for food)

Answer 7

Transports food from the leaves

Question 8

Transportation

Answer 8

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 )

Question 9

Stoma

Answer 9

Stoma are title holes underside of a leaf

Question 10

Transpiration stream

Answer 10

The flow of water from the roots up through the plant and the leaves is called the transpiration stream

Question 11

Photosynthesis

Answer 11

Theprosses were plants are made green

Question 12

Why are levee and plants green

Answer 12

Because contain chlorophyll with is a green chemical needed for photosynthesis

Question 13

Chlorophyll

Answer 13

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

Question 14

What parts contain chlorophyll

Answer 14

Any green part of a plant has chlorophyll

Question 15

Photosynthesis word equation

Answer 15

Carbon dioxide + water + ( sunlight and chlorophyll) -> glucose + oxygen

Question 16

Factors needed

Answer 16

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

Question 17

Products

Answer 17

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

Question 18

Plant responses

Answer 18

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

Question 19

Respiration

Answer 19

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

Question 20

Factors of respiration

Answer 20

Glucoses comes from food ,oxygen comes from air

Question 21

Products of respiration

Answer 21

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

Question 22

Anaerobic respiration

Answer 22

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

Question 23

Fermentation

Answer 23

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

Question 24

Parts of flower

Answer 24

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

Question 25

The stamen

Answer 25

Produces male sex cell

Question 26

Carpel

Answer 26

Female sex cell

Question 27

Life cycle of a plant

Answer 27

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

Question 28

Fertilisation

Answer 28

The union of nucleus of the pollen grain with the nucleus of the egg

Question 29

Fruit and sead development

Answer 29

After fertilisation the egg develops into the seed parent plant provides the growth

Question 30

Seed

Answer 30

The seed is provided its energy and raw materials to enable it to become established after dispersal,providing the environment is suitable

Question 31

Testa

Answer 31

The tough outer covering

Question 32

Radicle

Answer 32

The part browning down out of seed grows to form root

Question 33

Plumule

Answer 33

The part growing up this growing forms the shoot

Question 34

Food supply for seeds

Answer 34

The inside of the seed consists of sources of food

Question 35

Dispersal of fruit and seeds

Answer 35

Dispersal: * Wind * Insects * Self Example: Dandelion Strawberry Peas ( they pop)

Question 36

Germination

Answer 36

* Is the resumption of growth after a period of dormancy * mosture oxygen and heat are necessary for germination

Question 37

Asexuals reproduction

Answer 37

Formation of a new individual from the cells of one parent eg strawberry grass onion potatoes daffodils
