Botany Test Review
CHAPTER 27
1. Angiosperm - definition & characteristics
2. Monocot and dicot classes - characteristics
3. Life cycle of angiosperms - page 576
CHAPTER 31
1. Root and shoot systems
2. Morphology of winter twig lab
a. terminal bud has apical meristem
b. bud scale scars
c. lenticels
d. axillary buds
e. nodes and internodes
3. Types of plant cells to know:
a. parenchyma
b. tracheids and vessel elements
c. sieve tube and companion cells
4. Tissue systems of a plant
All plant tissues produced from apical meristem
a. dermal - (protoderm produces epidermis)
b. vascular - ( procambium produces primary xylem & phloem and vascular cambium, which produces secondary xylem and phloem
c. ground - ground meristem produces pith, cortex; cork cambium, cork
5. Growth in a plant is indeterminate
6. Know the following cross sections of plant tissue:
a. dicot root - root hair, epidermis, cortex, endodermis, pericycle, xylem, phloem
b. monocot annual stem - monkey face
c. dicot annual stem - rings of vascular tissue
d. leaf cross section - all parts
e. flower - all parts
f. seed - all
g. woody stem - all
CHAPER 32
7. T.A.C.T.
8. apoplastic and symplastic routes in root
9. endodermis coated on four sides by suberin. Casperian strip is name for waxy layer.
10. plasmodesmata
11. guttation
12. How do stomata open and close?
13. Pressure flow hypothysis
CHAPTER 34
14. Development of gametes in flower
Male:
anther - microspore mother cell (2n) - meiosis - 4 microspores (n) - pollen - mitosis --> tube cell - generative cell --> mitosis --> 2 sperm cells
Female:
carpel - megaspore mother cell (2n) - meiosis - 1 megaspore (n) - ovule in embryo sac - 3X mitosis - 8 nucleii (2 polar, 1 egg, 5 others)
15. Pollination (wind or insects)
16. growth of pollen tube
17. Double fertilization: 1 sperm + egg = embryo, 1 sperm + 2 polar nucleii = endosperm which becomes cotyledon(s).
18. Seed coat is an adaptation for land environment. (What are the other characteristics of angiosperms which also are adaptations?)
