1
Q

Plants are composed of

A

tissues; organs and organ systems

2
Q

2 organ system of plant

A

roots and shoots

3
Q

Roots are

A

below ground

4
Q

shoots are

A

above ground (stems, leaves, flowers)

5
Q

Eudicots have

A

two seed leaves (vascular bundles organized in rings), veins are like a maple leaf

6
Q

Monocots have

A

1 seed leaf (vascular bundles throughout), straight veins, like a celery

7
Q

Ground tissue system

A

functions for photosynthesis, and support

8
Q

Vasuclar tissue system

A

distributes absorbed water

9
Q

Dermal tissue

A

cover and protects surfaces

10
Q

Meristem

A

where plants arise from; undifferentiated cells

11
Q

Apical Meristem

A

length

12
Q

Lateral Meristem

A

thickness

13
Q

Parenchyma

A

primary growth of plant

14
Q

Mesophyll

A

consists of parenchyma cells that contain chloroplasts

15
Q

Meristematic cells are

A

unipotent

16
Q

terminal buds

A

main zones of primary growth in shoots

17
Q

lateral buds

A

axillary buds; form side branches, leaves, flowers

18
Q

root hairs

A

fine extension of root epidermis that increase the surface area for absorption

19
Q

cohesion/tension theory

A

water is pulled by evaporation from leaves so water can go high up to trees

20
Q

stomata

A

lots of water: guard cells open stomata

lack of water: guard cells collapse closing stomata

21
Q

tubers

A

potato type

22
Q

xylem carries

A

water and ions through plant

23
Q

phloem conducts

A

sugars and other organic solutes

24
Q

cork cambium

A

gives rise to periderm

25
Q

vascular cambium

A

yep of lateral meristem that produces secondary xylem and phloem
