15 of 78

Why are cells called as building blocks of life??

  • The cell is our most essential body forming unit. Each organ in our body is made of cells. Cells divide and multiply to form new organs and gametes too. 
  • The cell is called the structural and functional unit of life as all living organisms are made up of cells.
  • Cells are also essential for performing various life processes required for sustaining life.
  • Furthermore, cells provide form and structure, process nutrients and convert them into useable energy.
  • Multicellular organisms have specialized cells that perform specific functions.

Do plants have tissues???

38 of 78

-Vascular tissue transports water and nutrients from part of the plant to another

​

-Ground tissue provides storage and support to the plant, it is where photosynthesis takes place.

​

-Dermal tissue – It provides protection and helps reduce water loss

What is the function of skeletal system in the body-

  • The skeletal system works as a support structure for your body.
  • It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
  • The skeletal system is also called the musculoskeletal system.

Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones.

Bones

  • The adult human skeleton is made up of 206 bones.
  • These include the bones of the skull, spine (vertebrae), ribs, arms and legs.
  • Bones are made of connective tissue reinforced with calcium and specialized bone cells.

How are bones connected to other bones??

bones connected to other bones by tissues called Ligaments

When bones in joints move ,ligaments stretch, and keep the bones from shifting away from each other

What is the function of ligaments?
