Stigma and Style of Carpel

Carpel is the central part of a flower, and the stigma and style of carpel play a significant role in reproduction. Pollen that contains the male gamete lands on the stigma with often sticky surface to enter the ovary of the flower for fertilization. The style is a long stalk that connects the stigma and the ovary. The pollen tube is created inside the style to deliver the pollen grain,

CAM Plant

The pineapple in the picture is an example of a CAM plant. CAM refers to Crassulacean acid metabolism. It is a type of carbon fixation during which CO2 enters the stomata is converted into organic acids, which release the CO2 during the Calvin cycle when the stomata are closed. The CAM plant is able to adapt to arid environments.

Seed Dispersal

Seed Dispersal refers to the transport of seeds from the parent plant to other places. This photo of flowers represent seed dispersal. They cannot move freely as animals do, so they depend on seed dispersal to spread and reproduce.

Pollen

Pollen is the yellow powdery microspores of a plant. It contains the male gamete, which can fertilize when delivered to the female ovule. Pollen is often carried to the ovule by wind or animals, especially insects. This photo of a flower represents pollen because the flower contains pollen that must be transported to fertilize.

Phloem

Phloem is a plant tissue that transports organic foods to every part of the plant. This picture of celery represents phloem. The little shapes near the edges show phloem. Celery is a vascular plant in which phloem serves to deliver the organic compounds from the leaves to all the parts of the plant.
