The chloroplasts had inner membrane
Explanation:
The primitive photoautotrophs utilized hydrogen sulphide as the electron donor to perform photosynthesis for energy production.
Later upon understanding the endosymbiotic relationship of cyanobacteria which resided in the mitochondria of a eukaryotic host cell, the use of chloroplasts for photosynthesis was understood.
Generations after generations led to the development of chloroplasts by the cyanobacteria due to this symbiotic relationships which developed into the chloroplasts.
The unique presence of the inner membrane and its components like the stroma, thyllakoids helped the organism to utilize water as the electron donor for photosynthesis like the present day eukaryotes. This is the main reason why cyanobacteria is considered as the ancestor for eukaryotes.
The most common way these trees undergo pollination is through seeds and pollen.
The pollination is done with help of wind and birds where pollen transform from one plant to another.
<u>Explanation:</u>
The plants that undergoes pollination process through the seeds that are present in it are called as Angiosperms. These contains fruits. The seeds are usually present inside these fruits. Flowering plants are also called as Angiosperms.
These fruits and flowers are absent in gymnosperm. Even then they contain seeds inside the leaves surface. They will undergo pollination with these naked seeds. It is the fruits, flowers and the endosperm that are present in the seeds that help us to find difference between these two. The only common thing that exists between these two are seeds and pollen with which they pollinate.
In gymnosperms, pollen is transferred from male cone to female cone through wind or birds. Now, the pollen is germinated into pollen tubes and sperm for egg fertilization.
Answer:
Uranus
Uranus' axis is tilted, so it rotates from top to bottom.
