tissue and organs of multicellular organisms , The first section of plant organs
Individual cells → tissues → organs →
Macroscopic level the microscopic level
Plant organs
[Figure: Draw a Radish] (from the top leaves, stems, and roots. Root has two side columns)
= Leaf photosynthetic apparatus → (evolution) → flowers (reproductive organs)
In green, with chlorophyll. Make starch through photosynthesis.
Stem = organ-dori street
Little green
Root = organ absorbed
To absorb the nutrients.
● The first section leaves and flowers
Earth history
36 million years ago 46 million years ago, six million years ago, 165 million years ago, now three million years ago
↓ Paleozoic Mesozoic Cenozoic ↓ ↓ ↓ ↓ ↓
Prolific fossil fossil extinction extinction Earth's first organisms
Prosperity of the land living dinosaurs
Flower emergence of fossil leaves
Evolutionary process from stem to leaf
[Figure: Comparison of vascular bundle of leaf veins and stems]
Homologous with the leaf veins of the vascular pedicle
● The second term evolution of phyllotaxis
[Figure: Figure of the legume biplane]
[Figure: Diagram of compound leaf clover]
Get out of the leaf stalk
Because one notch in the leaf is being called a compound leaf leaf look. 1 is a single leaf leaf
Phyllotaxis types and evolution
[Figure: distichous phyllotaxis] → → 互生 whorled
The most familiar 互生. Superposed such as hydrangea and maple.
Primitive evolutionary
(Between the stem gradually reduced)
● The structure and evolution of flowers Section 3
Evolution of flowers from the leaf
Gathered on top of the stem leaves → (evolution) → differentiated sepals and petals stamen pistil
[Figure: Schematic diagram of the basic structure of the Flower
Primitive evolutionary stellar stellar
Flowers zygomorphic flowers actinomorphic
(The university petals automorphism
Come radially) (get a symmetrical petals)
Schizopetalous flower (the petals away) flower joint (combined under the petals)
[Figure: Sakura petals] [Figure:] [Figure pea petals: petals of chrysanthemums]
Zygomorphic zygomorphic actinomorphic
Schizopetalous joint schizopetalous flower flower flower
Why is distance from a star-petaled flower actinomorphic, joint venture or bilateral symmetry evolved?
→ to get specialized pollen carrying insects. Most especially is a good bee flight.
(You can also stop air flight, you can also approach the flowers down)
[Figure:] flying beetles and beetle-shaped, for example. Forewing is hard, not used to flying. As the flight landed I do not know where to.
Gadgets 鱗粉 the wings and the butterfly is rice, with less pollen.

Why have the petal colors and patterns?
→ is a message for a particular insect.
Bees can see ultraviolet light. The red light is invisible.
Central and ultraviolet light also show the yellow petals of the sorrel to absorb ultraviolet light, black.

Cabbage butterfly swallowtail butterfly and insects have the ability to show a red light.
The red petals of the azaleas, visit the swallowtail butterfly.
Including the swallowtail butterfly is the peak sensitivity to red light in 5 colors (by Arikawa).
Azalea pollen is the shrew of a butterfly against 鱗粉 have been consolidated in the sticky thread.
● The evolution of inflorescence Section 4
1) characterized by the rise from bottom to top indeterminate flowering, the flower stalk, which means a fall in the number growing on it indefinitely.

→ → racemose umbel capitulum (pollen and nectar can be collected efficiently.)
Scape shorter stem shortening during
★ capitulum from the flowers are in bloom around the (remnants of flowers that bloom from the bottom)
● The evolution of pistil Section 5
[Figure: Comparison of fruit and pistil pistil] cherry blossom and cherries, for example
Pistil fruit
Ovule and ovary pericarp seeds and pulp
Ovule in the pistil of one individual, so even there only 1 seed.
[Figure: Anatomy of peas. We have sketched actually dissected the Sayaendo]
Sepals and ovary ovule shows part of the pistil stigma and show Sayaendo
(Open = bean seeds are attached to opposite sides. One could prove fruit from leaf)
[Figure: Evolution of the angiosperm pistil]
Spores of the fern leaf → (spore sac that surrounds the leaf) → pistil in angiosperms
→ ovule spores and spore
[Practice] 演示 experiments.
1) Slice the bananas and cross-sectional view rooms = 3 in pistil 3 shows that the banana leaf evolved from single spores
2) Slice the apples from section 5 rooms (a star!) = Pistil has evolved from five leaf
3) Slice the orange section pistil are 10 rooms = 10 evolved from leaf
[Column] to put a few strands of orange peel in the Mukanai?
And an orange hull, white dots are lined up. The number of bunches in this number. This is a deep relationship that has evolved from the leaves and fruit. Considered that would be the point of petiole. One chamber of the leaf is one part that is what we eat has changed the surface of the leaf tissue. It was stored in the cell fluid that organization. (One grain of the storage solution has been explained that the orange one is a misunderstanding of cells and cell 『Biological Miyati Yuuzi ='s hypothesis)

The second section of plant tissue
● The first section meristem
Plant tissue is capable of limited cell division. Growth point and shoot apex and root tip and cambium in the stem of Dicotyledons angiosperms.
Elongation growth in the growing point (Takeshi Shigeru stretch), hypertrophic growth in the cambium (Osamu Shigeru fat) to the.
[Practice] and the observation of root tip meristem of cambium. Use acceptable preparations.
●The two permanent tissue sections
After the division of differentiated tissue cells. Are finely divided form and features.
The school system is to classify the organization would be relatively safe.
