Why do pollen grains have air-sacs?
Pollen grains have air-sacs to help them float in the air and be carried by wind or insects for pollination. The air-sacs provide buoyancy and allow the pollen grains to be dispersed more effectively to reach other flowers for fertilization.
Why do corn plants have two kinds of flowers?
Corn plants have both male and female flowers to allow for cross-pollination, which helps promote genetic diversity and improve the chances of successful reproduction. The male flowers produce pollen to fertilize the female flowers, leading to the development of corn kernels.
What adaptation allows plants to reproduce sexually while remaining stationary?
Pollinators allow for sex between plants. A host (usually an insect) called a pollinator will go from flower to flower collecting or eating nectar. This is the plants pay to its pollinator because upon leaving the flower the pollinator will have sperm (aka pollen) attached to its body and it will transport it to another flower where the pollen will germinate. Not all plants have flowers, many plants rely of wind dispersal of pollen (think grasses) while others require water (think ferns).
What kind of symbiotic relationship exists between plants and the bees that pollinate them?
Plants and bees have a mutualistic relationship where plants provide bees with nectar and pollen as food, while bees transfer pollen between plants to facilitate reproduction. This relationship benefits both parties, as plants can reproduce and bees can feed and support their colonies.
How do birds pollinate?
Birds can pollinate by transferring pollen from one flower to another as they feed on nectar. Some bird species have specialized beaks and tongues that allow them to access the nectar inside flowers while inadvertently picking up and depositing pollen. This process helps in fertilizing plants and aiding in their reproduction.
How does the kowhai flower pollinate?
Kowhai flowers are pollinated by birds, mainly tui and bellbirds, that extract nectar from the flowers while inadvertently transferring pollen between flowers. The curved shape of the flowers and positioning of the anthers and stigma allow for effective pollen transfer during feeding.

Why do trees bloom?
Trees bloom to produce flowers, which contain reproductive organs that allow them to reproduce. The blooming process attracts pollinators like bees and birds, which help transfer pollen between flowers, leading to fertilization and the production of seeds. Ultimately, blooming plays a crucial role in the tree's reproductive cycle and ensures the continuation of its species.
Why do pollen grains only produce tubes in flowers of their own kind?
because they dony like other species
Is it true or false that web-based software tools allow file sharing between multiple users?

Which sharing method does not allow you to pick the folder that is being shared?
