12/4- Oops all angiosperms (until tissues)

Question 1

Important characteristics of angiosperms?

Answer 1

Most diverse plant group.

Others:
- Carpel (female in flowers)
- Double fertilization, leading to endosperm
- Phloem containing sieve tubes and companion cells

Question 2

Monocots versus dicots?

Answer 2

M versus D

One cotyledon versus two cotyledons (seed leaves).

Flower parts in 3 versus flower parts in 4 or 5

Parallel, straight line leaf versus netlike leaves

Question 3

Double fertilization

Answer 3

One sperm leads to zygote

One leads to endosperm around zygote

Question 4

Two types of seed germination

Answer 4

Hypogenous (cotyledon below)

Epigenous (cotyledon above)

Question 5

Collenchyma versus parenchyma versus sclerenchyma

Answer 5

Parenchyma is thin and abundant. Collenchyma is thick and for structural support.

Sclerenchyma is DEAD, and is contained in things like bark. (makes up bark I mean)
