All plants:

• have roots, stems and leaves.

• are multicellular with tissues.

• have eukaryotic cells.

• are autotrophic organisms.

• live attached to the soil.

Unit 10

Vascular plants

Fronds (are the leaves with blades)

Rhizome (underground stem arranged horizontally) also known

creeping rootstalk

Roots

Seedless (spores)

Spores are produced inside the sporangium

They grow on shaded damp forests

Reproduction two types

asexual by spores,

sexual gametes, water is needed

Gametophyte (small fern only 8 mm, it bears gametes)

Sporophyte (visible fern it produces spores)

Pollination in plants

Plants

• Entomophily when pollinators are animals,

e.g bird (hummingbird) and the flowers

have coloured petals and a strong scent

Pollination in plants

Plants

• Anemophily is

carry out by

the wind and

they have

inflorescence

instead of

Plants interaction

Grapevines twisted itself

(Thigmotropism) is a

movement in which a

plant moves or grows in

response to touch or

contact stimuli

.
