Pollen tube
A flower cell is not a specific cell type. Flowers are made up of different types of cells, such as reproductive cells (eggs and pollen) and structural cells (petals, sepals). Cell types in flowers vary in function and structure, contributing to the overall growth and development of the flower.
The structure in the flower where sperm cells are formed is called the anther. It is part of the male reproductive organs of the flower and is responsible for producing pollen grains containing the sperm cells.
The structure of capillaries, with their thin walls and small diameter, allows for efficient exchange of materials between blood and cells in the body. The close proximity of capillary walls to surrounding tissues allows nutrients, gases, and waste products to easily pass through by diffusion. This structure ensures that vital substances like oxygen and nutrients can be delivered to cells while waste products can be removed efficiently.
Conjugation in bacteria occurs through a structure known as a pilus, which is a filamentous appendage on the cell surface. The pilus facilitates the transfer of genetic material, such as plasmids, between bacterial cells during conjugation.
Sperm cells move from the stigma to the ovules through a structure called the pollen tube, which grows down the style of the flower towards the ovary. This process is facilitated by the germination of pollen on the stigma, followed by the growth of the pollen tube to deliver the sperm cells to the ovules for fertilization.
It is blood cells
The structure that sticks out from the cell surface and allows it to move is called a flagellum. Flagella are long, whip-like structures that some cells use to propel themselves through their environment.

The cell membrane allows only certain things to pass in and out of the cell.
Plant cells interact with neighboring cells through the plasmodesmata, which are channels that traverse the cell walls and connect adjacent cells. This structure allows for the exchange of molecules such as nutrients, hormones, and signaling molecules between cells, facilitating communication and coordination in plant tissues. Through these connections, plant cells can coordinate growth, respond to environmental signals, and maintain tissue integrity.
The ovule in a flower is the structure that contains the female reproductive cells, known as the egg cells. It plays a crucial role in sexual reproduction by developing into a seed after fertilization, which eventually matures into a new plant.
