Hello! A: 1

The essence of starch is polysaccharides. For animals, the synthesis site of sugars is ** chondria, but starch cannot be directly present in the cell, because polysaccharides will be broken down when they encounter the corresponding enzymes, so it can only be said that sugars exist in the mitochondria or chloroplasts of the cell. In plants, sugars are synthesized within chloroplasts through photosynthesis.

Carbon dioxide, ATP

1·。There are root hairs.

2。The upper surface is strongly exposed to light, and there is a lot of water loss, and too many stomata will make the plant lack water. That's right.

1 1 In the primary structure, the root primary xylem is developed in the outer initiation style, and the stem is in the inner initiation type. Stems generally do not have an endothelial layer.

II 1The rhizome lies horizontally underground, with a long shape, much like a root.

2.The rhizome still retains the characteristics of the stem, i.e., having leaves (vestigial), axillary buds in the leaf axils, nodes and internodes.

3.The roots have a lot of hairy roots.

4.The rhizome generally has many small pits that sprout later, similar to those of potatoes.

5.The rhizomes are generally very hypertrophied, with more starch, and the roots are very thin and small, and the roots have more fibers.

The mechanical organization is well developed;

The palisade is organized in multiple layers, distributed on both sides of the leaf;

underdeveloped spongy tissue and intercellular space;

The veins are densely distributed;

The other is: 1) the leaves are hypertrophied and have well-developed water-storing parenchyma tissues;

2) High cell fluid concentration and strong water retention capacity.

Fugui bamboo (scientific name: Dracae sanderiana sander) is a perennial evergreen small tree foliage plant of the family Agave and Dracaena genus. The plant is elongated and erect with branches in the upper part.

rhizomes transverse, nodular; The stems are stout, erect, and delicate.

Native to the Gali Islands and tropical regions of Africa and Asia, Fugui bamboo has been introduced to China in large quantities since the late 80s of the 20th century.

Hello! This is a lantern plant.

Lanterns, also known as sour pulp, ghost lanterns, bitter lanterns, and yellow mushrooms, are plants of the genus Lamiaceae.

Tips for planting lanterns:

1. Seed selection: select excellent varieties with strong resistance to pulse, good quality and high yield.

2. Germination: First, it can be soaked in warm water for 20 hours, and the water is changed once every 8 hours for each shed, and then it is washed and cleaned, and then placed in 25 places to promote germination, and sowing after 70% of the seeds germinate. The second is to use the method of fine sand seed dressing chain town to promote germination, first use boiling water to disinfect the fine sand, put the seeds into a cloth bag, put them in the hotbed to promote germination, keep the temperature at 20-25, wash once a day with warm water, and germinate in about 4 days.

3. Sowing: Sowing in early April, covering a layer of soil after sowing, covering with plastic film to keep warm and moisturizing, and removing the plastic film after the emergence of seedlings.

4. Seedling management: before the emergence of seedlings, ensure that the temperature is 28-30 during the day, 25-28 after the emergence of seedlings, and not less than 15 at night. Seedlings are seedlings once in cotyledon time, and strong seedlings are retained; When 3 true leaves appear, they can be planted, and one week before planting, the film can be removed and the seedlings can be refined.

5. Land preparation: Choose flat, loose, fertile, and well-drained black loam land plots. It is best to practice crop rotation for more than 3 years.

In autumn, the soil is deeply turned, the leaves in the field are removed, the ridges are made one month before the lantern plants are transplanted, and the well-rotted farm manure, plant ash, tri-element or diammonium phosphate are applied as the base fertilizer when the soil is prepared, and then covered with film.

6. Planting: Planting is carried out in mid to late May, and watering is carried out after planting.

7. Field management: after planting, seedlings should be replenished, watered, and weeded in time. After flowering and fruit set, the foliar spray of potassium dihydrogen phosphate solution and dryland dragon at a concentration of 10 days is applied every 10 days. Avoid rain after spraying.

8. Pests and diseases: If powdery mildew is found, it can be diluted with chlorothalonil wettable powder mixed with water and sprayed; Ground tigers can be controlled by irrigating roots with phosphine emulsifiable concentrate mixed with water; Grubs can be controlled with homemade poisonous pesticides.

9. Harvesting: Harvest when the lantern plant fruit turns yellow.
