Lab 18-19-21 Flower Plants and Transport Flashcards
What are the vegetative organs of a plant?
- Roots 2. Stems 3. Leaves
Anchor plant and absorb water and minerals
Roots
Support Leaves
Stems
Carry on Photosynethesis
Leaves
Embryonic Tissue (apical0
Meristem
Three tissues in plants
- Dermal 2. Ground 3. Vascular
Outer protective covering
Dermal Tissue
Example of dermal tissue
Epidermis
Fills interior of plant, stores products of photosynthesis
Ground Tissue
Examples of ground tissue
Cortex Pith Mesophyll
transports products of Photosynthesis (water and sugar) and gives plant support
Vascular Tisue
Example of vascular tissue
Xylem Phloem Vascular Cylinder Vascular bundle Veins
When a plant increases in length
Primary Growth
Regions and Structures of the root
- Root cap 2. Zone of cell division 3. Zone of elongation 4. Zone of maturation
Dead cells for protection
Root Cap
Apical meristem, new cells are prodcued
Zone of cell division
New cells grow in length
Zone of elongation
Cells differentiate, has root hairs
Zone of maturation
Three different kinds of roots
- Tap root 2. Fibrous roots 3. Adventitious roots
Main root is many times larger than the branch roots, may store food
Tap root
All roots are almost same size
Fibrous roots
Develop from non root tissues (Prop roots and Aeria roots)
Adventitious roots
Root differences between monocot and euidcot
Monocot - root xylem and phloem in a ring Eudicot - root phloem between arms of xylem
Two different kinds of stems
- Herbaceous 2. Woody
Non woody stem, undergo primary growth (length)
Herbaceous
Undergo primary (apical meristem) and secondary growth (vascular cambium)
Woody
Stem differences between monocot and eudicot
Monocot - vascular bundles scattered in stem Eudicot - vascular bundles arranged in a distinct ring
Different types of stems
- Runners 2. Stolons 3. Rhizomes 4. Tubers 5. Corms
Two types of woody stems
- WInter twig 2. Woody stem
Terminal bud, terminal bud scar, leaf scar, bundle scars, node, axillary bud
Winter Twig
Bark, Vascular cambium, Wood, Pith, Rays
Woody Stems
Bark is made up of
- Cork 2. Cortex 3. Phloem
Leaf anatomy
- Cuticle 2. Upper epidermis 3. Lower epidermis 4. Mesophyll
Leaves may be arranged how?
- Simple 2. Compound 3. Arranged on a stem
