Why are no chloroplasts present in these pollen grains?
Pollen grains do not contain chloroplasts because they are not involved in photosynthesis. Instead, pollen grains contain other organelles such as mitochondria to provide energy for pollen germination and growth once it reaches the female reproductive organ of the plant. Chloroplasts are primarily found in the leaves of plants where photosynthesis occurs.
Why do pollen dies if its lands on an unripe stigma?
Pollen grains require a compatible and mature stigma to germinate and grow a pollen tube for fertilization. If pollen lands on an unripe stigma, it may not provide the necessary biochemical signals or nutrients for the pollen to survive and develop. Additionally, the stigma may lack the appropriate receptors or conditions needed for pollen germination, leading to the pollen's eventual death. Ultimately, the failure to establish a successful connection between the pollen and stigma prevents fertilization.
What is the purpose of using sucrose solution when germinating pollen grains?
Using a sucrose solution in germinating pollen grains provides a readily available energy source for the pollen grains as they begin to germinate. This helps to support metabolic processes and allows the pollen grains to grow a pollen tube, which is necessary for fertilization to occur.

Why do deciduos trees lose there leaves?
the pollen and air from the oxygen at this time of year makes the leaves dry up. this makes the roots loose their "hold" of the leaves and the leaves fall
What is a possible advantage of releasing pollen before the leaves expand in size?
self pollination
Why do pollen grains have a store of carbohydrates?
To provide food for the bees
What does a bee provide?
Bees provide honey, they also pollinate plants by transporting pollen.
How does reproduction occur in a flower?
The pollen of a male male flower is transported by a bumble bee or some other insect. The insect lands in a female flower and leaves the pollen behind.
Pollen and nectar produced by flowers provide what for butterflies and bees?
Food
Is this reproduction pollen grains are released from a flower?
Yes because the pollen then will later produce more and provide which is considered reproduction in term.
Why did your oak tree drop major leaves last year acorns the year before and now all the pollen this year?
The pollen is to produce acorns, which produce more oak trees.
How flowers live?
