PLANT SYSTEMATICS
39
● A British naturalist proposed the TEHORY OF BIOLOGICAL EVOLUTION by natural selection.
● He defined evolution as “descent with modification”
● Suggested a mechanism for evolution: NATURAL SELECTION
CHARLES DARWIN
40
It is the ADJUSTEMENT OR CHANGES IN BEHAVIOR, physiology, and structure of an organism to become MORE SUITED TO AN ENVIRONMENT
ADAPTATION
41
● VERY DRY AND OFTEN HOT
● Rain often comes all at the same time. The rest of the year is very dry.
● Lots of direct sunlight shining on the plants.
● Soil is often sandy or rocky and unable to hold much water.
● Winds are often strong, and dry out plants.
● Plants are exposed to extreme temperatures and drought conditions.
● Plants must cope with extensive water loss.
DESERT
42
● Some plants, called succulents
● Some plants have NO LEAVES or SMALL SEASONAL LEAVES that only grow after it rains.
● Long root systems spread out wide or GO DEEP INTO THE GROUND TO ABSORB WATER.
● Some plants have a SHOR LIFE CYCLE, germinating in response to rain, growing, flowering, and dying within one year.
● LEAVES WITH HAIR OR SPINE
● Waxy coating on stems and leaves.
● Flowers that open at night lure pollinators who are more likely to be active during the cooler night.
● Slower growing requires less energy.
DESERT PLANT ADAPTATIONS
43
● Called PRAIRIE, it features HOT SUMMERS ADN COLD WINTERS
● RAINFALL IS UNCERTAIN and DROUGHT IS COMMON.
● The SOIL IS EXTREMELY RICH IN ORGANIC MATERIALS due to the fact that the above-ground portions of grasses die off annually, enriching the soil.
● The area is WELL-SUITED TO AGRICULTURE, and few
original prairies survive today.
TEMPERATE GRASSLANDS
44
● During a fire
○ The root portions survive to sprout again
○ Some prairie trees have THICK BARK
○ Prairie shrubs READILY RESPROUT AFTER A FIRE
● ROOTS of prairie grasses EXTEND DEEP INTO THE GROUND
● Extensive root systems - prevent animals from pulling them
● Prairie grasses have NARROW LEAVES - loss water more
● Grasses grow from near their base, not from tip
● Grasses are WIND POLLINATED
● SOFT STEMS - bend
TEMPERATE GRASSLAND ADAPTATIONS
45
OTHER TERM FOR TEMPERATE GRASSLAND
PRAIRIE
46
● Is HOT AND RAINS A LOT
● Abundance of water problems:
○ Harm to plants due to growth of bacteria and
fungi.
○ Risk of flooding. Soil erosion and rapid loss of nutrients from the soil. Rapid growth of plants.
● VERY THICK AND NOT MUCH SUNLIGHT is able to penetrate to the forest floor.
TROPICAL RAINFOREST ADAPTATIONS
47
● DRIP TIPS AND WAXY SURFACES - water run off
● BUTTRESSES, PROP, AND STILT ROOTS - help hold up plants
● Some plants climb on other plants
● Flowers on the forest floor are designed to lure animal pollinators due to no wind
● SMOOTH BARK and smooth or waxy flowers speed the
run off of water
● Plants have SHALLOW ROOTS - capture nutrients
● Many bromeliads are epiphytes (plants that live on
other plants);
● Epiphytic or orchids have aerial roots
TROPICAL RAINFOREST ADAPTATIONS
48
PLANTS THAT LIVE ON OTHER PLANTS
EPIPHYTES
49
● The ___________ features MINIMAL SEASONAL FLUCTUATION OF TEMPERATURE: the winters are mild and the summers cool.
● Condensation from coastal fogs also adds to the dampness. The SOIL IS POOR IN NUTRIENTS.
● A nurse log is a fallen tree which, as it decays,
provides ecological facilitation to seedlings.
TEMPERATE RAINFOREST
50
a fallen tree which, as it decays, provides ecological facilitation to seedlings.
NURSE LOG
51
● Epiphytes such as mosses and ferns grow atop other plants to reach light.
● Cool temperatures lead to slow decomposition but seedlings grow on “nurse logs” to take advantage of
the nutrients from the decomposing fallen logs.
● Trees can grow VERY TALL due to the amount of precipitation.
TEMPERATE RAINFOREST ADAPTATIONS
52
- TERRESTRIAL biotic communities
- area na naca-classify depende sa species na nakatira doon
BIOMES
53
● Temperature varies from HOT IN THE SUMMER TO BELOW FREESING POINT IN THE WINTER.
● RAIN IS PLENTIFUL
● Made up of layers of plants
○ The tallest trees make up the forest canopy.
○ Beneath the canopy, the understory
○ Below the understory is a shrub layer.
○ Carpeting the forest floor is the herb layer made up of wildflowers, mosses, and ferns.
● Fallen leaves, twigs, and dried plants cover the ground, decompose, and help add nutrients to the topsoil.
TEMPERATE DECIDUOUS FOREST
54
● Wildflowers grow on forest floor early in the spring before trees leaf-out and shade the forest floor
● Many trees are deciduous
● Most deciduous trees have thin, broad, lightweight leaves
● When the weather gets cooler, the broad leaves cause too much water loss and can be weighed down by too much snow
● Trees have thick bark to protect against cold winters
TEMPERATE DECIDUOUS FOREST ADAPTATIONS
55
● Also known as BOREAL forests
● The taiga is dominated by CONIFERS and most of which are evergreen
● The taiga has cold winters and warm summers.
TAIGA PLANT
56
● Many trees are EVERGREEN
● Many trees have NEEDLE-LIKE LEAVES which shape loses less water and sheds snow more easily than broad leaves
● Waxy coating on needles to prevent evaporation
● Needles are dark in color allowing more solar heat to be absorbed
● Many trees have branches that DROOP DOWNWARD to help shed excess snow to keep the branches from breaking
TAIGA OR BOREAL FORESTS ADAPTATIONS
57
● COLD YEAR-ROUND– it has SHORT COOL SUMMERS and
long, severe winters.
● Has a PERMANENTLY FROZEN sublayer of soil called PERMAFROST.
● Drainage is poor due to the permafrost and because of the cold, evaporation is slow.
● The _____ receives little precipitation and is usually in the form of snow or ice
● There is a LITTLE DIVERSITY of species. Plant life is dominated by mosses, grasses, and sedge
TUNDRA
58
● _____ plants are SMALL (usually less than 12 inches
tall) and LOW-GROWING due to lack of nutrients
● Plants are DARK IN COLOR
● Some plants are covered with hair which helps keep them warm.
● Some plants grow in clumps
● Some plants have DISH-LIKE FLOWERS that follow the sun
TUNDRA ADAPTATIONS
59
a permanently frozen sublayer of soil
PERMAFROST
60
● Underwater leaves and stems are FLEXIBLE
● Some plants have AIR SPACES in their stems
● Submerged plants absorb water, nutrients, and dissolved gases through the leaves directly from the water.
● Roots and root hairs reduced or ABSENT
● Some plants have leaves that FLOAT atop the water
● In floating plants chlorophyll is restricted to upper surface of leaves (part that the sunlight will hit)
● Some plants produce seeds that can float
