28 Plant Structure

Question 1

Monocot

Answer 1

One cotyledon
Parrel vein
Scattered vascular tissue
One opening pollen grain
Fibrous
Floral organs 3 multiple

Question 2

Eudocot

Answer 2

2 Cotyledon
Netlike veins
Ring vascular tissue
Three opening pollen grain
Fibrous roots
Floral organs 5 multiple

Question 3

Taproot

Answer 3

One large root structure anchors the plant and aches as storage. Allows plants to survive drought

Question 4

Fibrous

Answer 4

It has a very high area to /v ratio when compared to taproot. Spreads out underground allowing for recourse acquisition. Faster absorption

Question 5

Root Function

Answer 5

Structure - Anchor
Nutrient uptake / Water uptake
Storage

Question 6

Stem Function

Answer 6

Transport nutrients and water leaves - roots
Support
Storage
Move stem the best photosynthesis (Auxin bending away)

Question 7

3 Tissue types of plants

Answer 7

Dermal
Ground
Vascular

Question 8

Dermal - Protoderm

Answer 8

Thin outer protective layer on Stem, Roots, Leaves

Question 9

Ground - Ground meristem

Answer 9

Like a filler in the plant covers areas that vascular and dermal do not.

Question 10

Vascular - Procambuim

Answer 10

Xylem - transport of water
Phloem - transport of sugars

Question 11

Three types of plant cell

Answer 11

Parenchyma
Collenchyma
Sclerenchyma

Question 12

Parenchyma

Answer 12

Thin cell wall
Photosynthesis
Alive

Question 13

Collenchyma

Answer 13

Support when alive
Protection
Alive

Question 14

Sclerenchyma

Answer 14

Support when dead
Protection
DEAD

Question 15

Xylem

Answer 15

Tracheids - Tranposrt of water minerals
Vessel elements - system of transportation (tubular vessel)

Question 16

Phloem

Answer 16

Sieve tube element - transports carbs or sugars.
Companion cells - Providing energy to sieve tube / metabolic support loading and unloading

Question 17

Primary

Answer 17

Vertical growth
Apical Meristem

Question 18

Secondary

Answer 18

Horizontal growth
Lateral Meristem
Cork cambium - Epidermis becomes perderm
Vascular cambium - Layers of 2nd Xylem Phloem

Question 19

Structure Root cell.

Answer 19

Epidermis
Root hairs
Cortex
Endodermis
Pericycle

Question 20

Root primary growth

Answer 20

Zone Cell Division
Zone Cell Elongation
Zone Cell Maturation
Three tissue creates
Formation lateral root

Question 21

Shoot primary growth

Answer 21

Same Root
Leaf primordia
Intercalary meristem

Question 22

Tree rings formed

Answer 22

Vascular cambium - 2nd xylem phloem
Old xylem dies hardens, old phloem falls off
Deadronology
