Let’s draw and label the life cycle of a mushroom
Please sketch the following diagram in your notes…it will be helpful in the future!
Kingdom Plantae Multi-cellular Autotrophic Eukaryotic Cell walls made of cellulose Store food in the form of starch
VascularHave vessels to
transport food and water
They have roots, stems or leaves
Ex: grass, corn, trees, flowers, bushes
Seed Plants Gymnosperms have seeds
that are not enclosed. "naked seeds" cone bearing plants (seeds
grow on cones) needle like leaves usually stay green year
round wind pollinated Examples: pine trees &
evergreens
Angiosperms are the most successful group of plants
They have co-evolved with insects to improve pollination.
Flowering plants Seeds are enclosed, usually in a fruit Most are pollinated by birds & bees Have finite growing seasons Examples: grasses, tulips, oaks,
dandelions Divided into two main groups:
Monocots & Dicots
Monocots Angiosperms have 1
seed leaf (cotyledon)
parallel veins on leaves
3 part symmetry for flowers
fibrous roots Example: lilies,
onions, corn, grasses, wheat
Vascular tissue scattered
Dicots Angiosperms that have
2 seed leaves (cotyledons)
net veins on leaves flowers have 4-5 parts taproots Examples: trees and
ornamental flowers Vascular tissue
arranged in a ring
Success of Angiosperms
Transport gametes over great distances.
Efficient dispersal via fruit. Tough, water resistant leaves for
survival in hostile environments.
Pollination
Birds are attracted to red flowers.
Bees can see colors that humans cannot.
Moth-pollinated flowers are white and bloom at night.
Many insects are attracted to odors. One species smells like rotting meat and is pollinated by flies.
Flowers are often shaped so that non-pollinators cannot reach nectar or pollen. For example, hummingbird-pollinated flowers are long, and shaped like the bill of a hummingbird.
Wind-pollinated flowers are small, have no petals and little color and do not produce nectar.
Problems living in a terrestrial ecosystem
Support - in water, the plant is held up. On land, a support system is required.
Getting Water and Nutrients Aquatic plants are surrounded by water and
nutrients so most cells can just absorb them the environment. Terrestrial plants require a system for collecting and transporting water.
Plants developed root systems that can collect and transport water. Some plants have shallow roots which spread out to collect water.
Water carrying minerals from the roots can travel to all parts of the plant and food made in the leaves can travel to non-photosynthetic parts of the plant.
Drying Out Leaves are covered by
a waterproof outer layer called the cuticle.
Openings in the leaves called stomata allow passage of gases for photosynthesis but can be closed when it is too warm.
Gymnosperms have very narrow leaves to minimize water loss.
Spreading Gametes
Spores – tiny reproductive cells are carried long distance by the wind
Seeds: – The embryo inside the seed is surrounded
by a tough, drought-resistant, protective seed coat. Food packaged in the seed provides energy for the young plant until it can grow above the soil and begin photosynthesizing.
– Adaptations of seeds help in their dispersal. Some seeds are carried by wind, stick to the fur of animals or are eaten.
