Answer 2

Answer:

1)The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:

supports the body.

facilitates movement.

protects internal organs.

2)Blood has many different functions, including:

transporting oxygen and nutrients to the lungs and tissues.

forming blood clots to prevent excess blood loss.

carrying cells and antibodies that fight infection.

bringing waste products to the kidneys and liver, which filter and clean the blood.

3)The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

4)The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

5)

• absorption of water and inorganic nutrients;
• anchoring of the plant body to the ground, and supporting it;
• storage of food and nutrients;
