1. Agiosperm wood has vessels as compared to conifers wood. Vessels can be defined as cells stacked end to end. Water is able to flow freely among them and otherwise vessels are called pores. However, conifers wood has resin canals that should not be confused with pores though they might look a little similar. Conifers wood is sometimes referred to as gymnosperms.
2.
A. It is a part of sapwood.
B. It is monocot.
C. Monocots have inside their seed coats one seed leaf while dicots have two. Monocots’ leaves are thin due to the fact that the endosperm lies outside the seed leaf. Dicots leaves containing endosperm inside of them and feeding it to the embryo plant have, as a rule, rounded and fat leaves.
D. Xylem
E. Ground tissue system
3. A. It is heartwood
B. It is a dicot
C. On pictures of heartwood dicot has a much smaller nucleus, or pith, while monocot has a one that is big. It can be due to the fact that monocot represents just a single leaf while dicot represents two leaves.
D. Tissue A is dermal epidermis
E. Structure B is epidermis
F. Tissue C is a ground tissue
4. A. It is sapwood.
B. It is monocot.
C. Primary vascular bundles are scattered in monocots while dicots have vascular bundles in a ring.
D. Dermal epidermis
E. Pores
F. Both tissues refer to transport tissues but specifically C is xylem and D is phloem
5. A. Ring Porous structure
B. Pith
C. dicots
6. The function of xylem is to transport water
The function of phloem is to carry organic nutrients such as sugar, for example.
Ground tissue’s function is to form certain parts of wood, for example pith of stems.
7. A. Heartwood
B. Phloem and xylem. The function of xylem is to transport water.
The function of phloem is to carry organic nutrients such as sugar, for example.
C. Angiosperms
8. A. Lateral root initiation starts with divisions in adjacent xylem cells. It is controlled by successive auxin response modules.
B. Secondary growth usually makes the root much thicker. On the other hand, primary growth elongates and ramifies the root system. Monocots, as a rule, do not have the second growth.
9. 1. Cell walls include plasmodesmata
2. The cells themselves are thin and flexible.
3. The cells possess a large central vacuole
10. 1. Produce lateral roots in eudicots.
2. In angiosperms it promotes the root meristems’ growth
3. In plants it helps the vascular cambium to be transformed into a cork cambium
