16
Q

Guard cells

A

In dermal tissues, these cells form openings called stomata (stoma singular). Allows gasses to be exchanged with the environment

17
Q

Ground Tissue

A

Function: Photosynthesis, food storage, and mechanical support

18
Q

Vascular Tissue

A

Provides movement of materials through roots, stems, and leaves

19
Q

Xylem Tissue

A

A type of vascular tissue. This tissue is dead. Carries water and minerals from the roots to the rest of the plant

20
Q

Phloem Tissue

A

Transports sugar from one part of the cell to another. Living cells

21
Q

Vascular Cylinder

A

Vascular tissues found at the centre in a shaft

22
Q

Cortex

A

Stores materials for the plant

23
Q

Apical Meristem

A

Growing tip of the meristem tissue

24
Q

Root cap

A

Protects the apical meristem from soil erosion. Flakes off as it’s pushed into the soil

25
Q

Zone of cell division

A

Area above the apical meristem

26
Q

Zone of elongation

A

Once cell division stop, growth keeps happening in this area

27
Q

Zone of maturation

A

Cells may mature into adult tissues (dermal, ground, vascular)

28
Q

Epidermis

A

A single layer of dermal cells

29
Q

Herbaceous Stems

A

Soft and green, little growth in diameter, covered by epidermis, dicots and monocots

30
Q

Woody Stems

A

Hard and brown, considerable growth in diameter, covered by a corky bark. Dicots only

31
Q

Monocot Flowers

A

Typically arranged in multiples of 3 ( sepals, petals, stamens)

32
Q

Dicot flowers

A

Typically arranged in multiples of 4 or 5
