1. Hi~ It's me I'll tell you whether there is a bus in the passenger transport center, but there is no bus to Jinshan District. Unless, the transfer is about 3 hours. If it's faster, it's about 3 hours. Because I have been to... Ha ha, but not to Jinshan District. But it's also this time! How to transfer! I don't understand this!. Sister~ That's all I can do for you!
2. About 12.30 to Shanghai South Railway Station. The north station may be 45 minutes late and an hour late. The ticket price is about 105-120 yuan.
3. Mature plants have no centrosome
lower plants have centrosome
the reason why mature plants have no centrosome is that the role of centrosome is to assist cells in mitosis
while mature plant cells directly form spindles to form spindles, which do not require the centrosome to emit Star rays to form spindles
and the direct reason here is because of the cytoplasm There are a lot of microtubules and microfilaments. After the metaphase of mitosis, these microtubules aggregate to form spindles<
the cells of lower plants do not develop completely and do not form mature microtubules and microfilaments, so it is necessary to form spindles with the help of centrosomes
as for how to distinguish between cell animals and plants (cell wall)
if we look at plants first, then we can see whether there are mature large vacuoles (more obvious)
if we look at mature plants, we can see whether there are mature cells If there is a centrosome, it means that the lower plant cells have centrosomes
hope to help you. If you don't understand, you are welcome to ask

4. Lower plants and animals have centrosomes, higher plants have spindles but no centrosomes. Centrosomes are related to cell mitosis
5. Only the lower plants have a centrosome, which is one and contains two centrioles
higher plants have no centrosome
higher plants have no centrosome
6. No
centrosomes are found in lower plant cells.
centrosomes are found in lower plant cells.
7. It's not "molecules and cells" in biology compulsory 1 (PEP) of the new curriculum standard
the original words about centrosomes from the third to the last line on page 46 are: "centrosomes are found in the cells of animals and some lower plants"
since they are some, not all lower plant cells have centrosomes
it usually does not exist in the somatic cells of higher plants, but it appears in the sperm cells of liverworts, ferns, iron trees and other plants with flagella or cilia. Even in lower organisms, there are such examples. For example, there is no centrosome in Amoeba
centrosome like cells, but centrosome also appears ring its movement to flagellum cells
