The periosteum consists of two layers-
1. Outer fibrous layer
2. Inner cellular layer
- It is mainly composed of dense irregular connective tissue along with a layer of simple squamous epithelium.
- The function of periosteum is to cover the surface of all the bones except those surfaces that are covered with cartilage such as joints and tendons and ligaments.
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
