Plants

Question 1

How would you describe a plant?

Answer 1

Photosynthetic
Autotrophic
Eukaryotes
Have cell walls

Question 2

What is dessication?

Answer 2

Loss of moisture

Question 3

What does it mean if a plant is poikilohydric?

Answer 3

It can tolerate dessication, not damaged

Question 4

What does it mean if a plant is homiohydric?

Answer 4

It regulates its internal water balance and uses water proofing and water retaining methods to avoid dessication. Damaged if water balance not maintained

Question 5

What are some water proofing/retaining methods?

Answer 5

Vascular tissue
Stomata
Upper cuticle
Thick leaves (internal air spaces)

Question 6

What are the two kinds of vascular tissue?

Answer 6

Xylem

Phloem

Question 7

What does xylem do?

Answer 7

Carries water and minerals

Question 8

What does phloem do?

Answer 8

Carries sugars produced by plant

Question 9

Does xylem use single or multidirectional transport?

Answer 9

Single

Question 10

Does phloem use single or multidirectional transport?

Answer 10

Multi

Question 11

What is the cuticle?

Answer 11

Thick, waxy, protective film covering the epidermis of leaves

Question 12

What is stomata?

Answer 12

Tiny holes found on the underside of leaves, used to control water loss and gas exchange

Question 13

What is the role of internal airspaces in leaves?

Answer 13

Reduce the surface area, making it less exposed, less risk of drying out. Gas exchange may also occur internally within pockets

3. Xylem

Question 16

What adaptations have land plants formed to aid with light radiation?

Answer 16

1. Thick, waxy cuticle

2. Thicker leaves with internal air pockets

Question 17

Diploid (2n) best describes which stage of the plant lifecycle?

Answer 19

Sporotophyte

Question 20

Haploid (1n) best describes which stage of the plant lifecycle?

Answer 20

Gametophyte

Question 21

What adaptations have land plants utilized to help with offspring dispersal?

Answer 21

1. Use of wind
2. Self dispersal
3. Use of animals
4. Water

Question 22

Question 24

Are cells in phloem living or dead?

Answer 24

Question 25

Describe monophyletic groupings?

Answer 25

A group of organisms and their common ancestor, form a single clade and have shared derived traits
