Plant cells have certain distinguishing features, including chloroplasts,cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules. Why do...

Actually, too much sunhht cantdrage plant cells. To guar d against this, plants have something like a safety valve(). If it coul d react to changtog light faster, plants coul d get more sun energy, Nigiy.Three proteins control the opening an d closing of those salety valves. To ...
Bacteria Reproduction. Just like any other organism, bacteria also reproduce to continue their species. Since they are unicellular and do not have a well-organised cell, bacteria have been grouped under prokaryotes. However,they do show both sexual and asexual means of reproduction. ...
根据第二段中“Actually, too much sunlight can damage plant cells. To guard against this, plants have something like a safety valve (阀). If it could react to changing light faster, plants could get more sun energy, Niyogi says.(事实上,过多的阳光会损害植物细胞。为了防止这种情况,植物有一...
What cellular structure is found in prokaryotic cells, plant cells, and animal cells? What do prokaryotic and eukaryotic cells have in common? What are the structures found in both eukaryotes and prokaryotes? What do prokaryotic cells lack compared to ...
During the upward stage, dandelion seeds must attain a specific altitude to disperse from the parent plant. Wind speed and air humidity are two of the factors affecting the height the seeds can attain. This stage is characterized by two distinct weather conditions, as follows. Case 1—Clear da...
Because plant cells do not break down glucose by-products using oxygen, they do not have or need mitochondria. Instead, plants possess chloroplasts, which in effect convert light energy to chemical energy. Each plant cell has anywhere from 15 or 20 to about 100 chloroplasts, which, like mitoch...
How many chromosomes are in a plant cell? How many chromosomes are in a heart cell? How many chromosomes does someone with Down Syndrome have? How many chromosomes does each daughter cell have? How many chromosomes did Neanderthals have?
How do plant cells multiply? When plants reproduce asexually, they usemitosisto produce offspring that are genetically identical to the parent plant. ... When plants reproduce sexually, they use meiosis to produce haploid cells that have half the genetic information of the parent (one of every ...
