Q

Bryophytes

A

Small green plants, Grow on soil, rocks, other plants and produce spores

17
Q

Algae

A

Live in damp places, mostly water

18
Q

Ferns

A

Green plants, grow on soil, other plants, produce spores on back of leaves

19
Q

Gymnosperms

A

Woody trees and shrubs, male and female cones, thin leaves

20
Q

Angiosperms

A

Flowering plants, most common plants we see

21
Q

Cuticle

A

Protects against extreme temperatures, UV and chemical attacks

22
Q

Upper epidermis

A

Prevents water loss and provides extra layer between outside and inside.

23
Q

Palisade mesophyll layer

A

Maximise energy production during photosynthasis

24
Q

Spongy mesophyll layer

A

To allow interchange of gases that are needed for photosynthesis

25
Lower epidermis
Allows carbon dioxide to enter leaf and oxygen and excess water to exit the leaf
26
Stomata
Regulate flow of gases in and out of plants
27
Xylem cells
Transports water from roots to stems and leaves, also transports nutrients
28
Phloem cells
Transports sugars out of the leaf to rest of plant
