16
Q

Seed bearing plants

A

Homosporous
Higher vascular plants
Reproduce by seeds
Resistant seeds
Pollen grains produced from microspores

17
Q

Cone bearing plants

A

Needle like leaves
Single vein
Male cone has pollen sacks which bursts to reach megasporangium

18
Q

Flowering plants

A

Flower attracts pollinators to stigma
Remain genetically strong as self pollination is avoided

19
Q

What will happen if there’s no pollination

A

No fertlisation
No production of fruit & seed crops
Natural ecosystems collapse
Animals die

20
Q

Classes of flowering plants

A

Monocotyledons
Dicotyledons

21
Q

Monocots

A

Single seed leaf
Narrow leaves
Parallel veins
x3 flower parts
Not separated into sepals & petals
Scattered vascular bundles
No secondary thickening
Fibrous leaves
Wind pollinated

22
Q

Dicots

A

Two seed leaves
Broad leaves
Network of veins
x4/5 flower parts
Has Sepals and petals
Ring vascular bundles
Secondly thickening
Tap root
Insect pollinated

23
Q

What does the stamen have

A

Anther and Filament

24
Q

What is the Anther

A

Where pollen is formed

25
Q

What does the Carpel have

A

Stigma
Style
Ovary
Ovule

26
Q

What happens to the ovary and the ovule

A

Ovary- mature into fruit
Ovule- forms seed after fertilisation

27
