M8 Plant Anatomy & Physiology Flashcards
TRUTH OR FALLS
Plants/Plant Kingdom are multicellular organisms
Truth!
These are also called spermatophyte
Seed bearing plants
These has seeds but do not bear flowers.
Gymnosperm
These has seeds and bears flowers.
Angiosperm
A botanist is listing down the characteristics of angiosperms. Which of the ff is not one of them?
A. Naked seeds
B. Undergoes double fertilization
C. Fruits and vascular tissues
D. Its flowers are pollinated by insects
A.
Naked seeds are evident in gymnosperms.
Zea mays (corn), are categorized under monocots. Which of the following characteristics is expected to be found in corn?
A. Netted leaf venation and tap root
B. Two cotyledons
C. Circular arrangement of vascular tissues
D. Parallel lead venation and fibrous root system.
D.
Provides the characteristics of monocots.
TYPES OF PLANT CELLS:
Thin, primary walls that retain their protoplasm at maturity. Some of its functions are cells in leaves for photosynthesis and respiration.
Parenchyma cells.
PLANT TISSUES:
Outer covering of the leaves, stems and roots
Dermal tissues
Thin layer over the external part of the dermal tissue to prevent water loss; absent in roots
Cuticle
Control water lost of transpiration; allows gas exchange
Stomata
These tissues actively divide and is located at the tips (shoot and root)
Meristematic Tissues
Female part of a flower
Pistil / Carpel
This part of the (female) flower is the sticy part which catches the pollen
A. Style
B. Ovary
C. Stigma
C. Stigma
What is the male part of a flower?
Stamen
Which of the male part of a flower holds the anther (the one which releases the pollen) upright?
Filament
During hot days, the guard cells close the stomatal pore. The main purpose of this is because:
A. High temp. Makes the stomata’s function irrelevant to the plant.
B. High temp. Makes CO2 enter the plant in other openings other than the stomata.
C. High temp. Makes H2O easier to leave the plants, so guard cells mame sure that the stomata is closed to prevent further water loss.
D. High temp. Drives H2O into the stomata, so guard cells make sure that the stomata is closed to prevent excessive water entry.
C.
In Professor Geller’s plant anatomy class, the topic involves the fundamental tissues of plants. In their lesson, the tissue for photosynthesis is in question. Which of the ff is involved in photosynthesis?
A. Dermal tissue
B. Meristematic tissue
C. Ground tissue
D. Vascular tissue
C. Ground tissue
Also known as phytohormones
Plant hormones
Occurs when the pollen attaches to the stigma, elongates down the style, and releases two spermatozoa into embryo sac, which fertilizes the egg and polar nuclei
Pollination
This plant hormone promotes seed dormancy and counters the effect of auxin.
A. Gibberelline
B. Ethylene
C. Abscisic acid
D. Cytokinin
C. Abscisic acid
