Question

State the main function of the following:
1) lips ii) canines, iii) Mitochondria, iv) Fruit, v) Midrib of a leaf.​

Answer 1

Lips : Lips serve to close the mouth airtight shut, to hold food and drink inside. Lips help to hold food between upper and lower teeth during chewing.

Canines : There are four canines in the oral cavity. Two in the maxillary arch and two in the mandibular area. They are behind and adjacent to the lateral incisors. Their main function is to tear food.

Mitrichondria : Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Fruit : The two main functions of fruit are to prevent the seeds from drying and to disperse the seed. The fruit may be either fleshy or dry. Fleshy fruits, like the tomato or apple, hold juices that prevent the seeds from drying until they are mature. Fleshy fruits also serve to help disperse the seeds.

Midrib of a leaf : A midrib provides strength throughout the leaf, keeping it upright and sturdy in the wind. Chlorophyll is the green pigment that absorbs sunlight. Veins transport water and glucose around the plant.
