Answer:
The correct option is formation of bone from within fibrous membranes.
Explanation:
The process of intramembranous ossification results in the production of bones from the fibrous membranes. The mesenchymal cells get differentiated into different kinds of osteoblasts. The process of intramembranous ossification occurs in the skull. In other parts where bones are to be formed by this process, the mesenchymal cells get converted into cartilage first. The cartilage will then be converted or replaced into bones.
Bones at the base of the skull and the long bones are produced by endochondral ossification.
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.
Answer:
Its a vascular plant
Explanation:
- These plants are called tracheophytes
- They have specialized vascular system for conduction of minerals and water
Following are their characteristics:-
- they have phloem tissue for transport of food
- xylem tissue transports the water in the plant
- becuase of the transport system they are able to grow larger
EXAMPLES
- Ferns
- Angiosperms
- Gymnosperms
pollination- the act of transferring pollen grains from the male anther of a flower to the female stigma.
Pollen tube germination- pollen tubes act as conduits to transport the male gametes cells from the pollen grain, from the stigma to the ovules.
