UCF BSC 1005 Exam 3 Questions and Answers (UCF, Donnelly,
BSC1005, BSC 1005: Biological Principles, Exam 3 study guide)
What are the types of tissues found in plants? - -meristem tissue & permanent tissue
(dermal, ground, vascular)
-Meristem tissue - -undifferentiated cells that divide
- new growth in stems & roots
- produces permanent tissues
-Dermal tissue - -densely packed layer of cells
- "skin" of plant; protection, insulation, water conservation
-Ground tissue - -composed of multiple types of cells
- synthesizes organic molecules
- supports structures
- storage
-Vascular tissue - -1. xylem - transport water & minerals from roots
2. phloem - transport sugar & nutrients from leaves to rest of plant
-What plant organs make up the shoot and root systems? - -Shoot: Flower, Terminal
bud(shoot apex), node, internode, axiliary bud, terminal bud of branch, vegetative branch,
Leaf: Petiole & blade
Stem (rhizomes)
Root: Taproot & lateral roots.
-Mycorrhizae - -symbiotic association between plant roots and fungi
-Nitrogen Fixation - -process of converting nitrogen into a useful form
-What types of plants are considered angiosperms? - -flowering plants: grasses and
orchids
- reproduce by seeds inside of an ovary
-What adaptations do plants have for water conservation? - -- thick, succulent
leaves
- waxy secretions on
leaves & stem
- wilting
-How do bees benefit plants? - -bees are one of the most
common generalist pollinators
- evolutionary relationship with eudicots
, -What are the negative effects of losing bees? - -loss of ecosystem service:
- lower rates of pollination = decline in flowering plants
- decreased food supply = bees pollinate ~30% of human food supply
-Possible causes of bee decline - -- Pesticides
- Mites
- Viruses
- Non-Native bees
- Potentially cell phone towers
-Transpiration - -movement of water through a plant
-Angiosperm - -flowering plants (grasses and orchids); reproduce by seeds inside of an
ovary; majority of plants.
-Gymnosperm - -plants produced by ovary (fruit)
-Dicot - -Orchids, palms, lilies, grasses:
- single cotyledon
- long narrow leaf; veins are parallel
- vascular bundles scattered
- flower parts in multiples of three
-Monocot - -Trees, shrubs, herbs:
- two cotyledons
- broad leaf; network of veins
- ring of vascular bundles
- flower parts in multiples of five or four
-Stomata - -small pores on leaves
- exchanges gases with the atmosphere
-What are the 4 types of tissues found in animals? - -connective, epithelial, muscle &
nervous tissue
-Epithelial tissues - -Function: cover body surfaces
- skin
- lining of internal organs, blood vessels, digestive tract
Structure: Sheets of closely packed cells
- protective barrier
- surface for water and gas exchange
