Answer:
The correct answer will be - the sugar is not transported to roots
Explanation:
The girdling is performed on tress by making a groove of 1 cm in the bark of a tree.
The girdling activity removes the phloem tissue of the trees which help in the conduction of the sugar and other useful nutrients in the trees.
Since the phloem is present on the outside portion of the vascular cambium due to the secondary growth, therefore, removing the bark and making a groove in the tree removes the portion of the phloem. The removal of the phloem stops the blockage of the sugar to the roots as a result of which the root dies and water is not absorbed. This leads to the death of the tree after some time.
Thus, the sugar is not transported to roots is the correct answer.
Yes they do, indoor plants remove pollutants from the air by absorbing these gases through their leaves and roots.
Answer:
The correct answer is a. They release their secretions into the blood.
Explanation:
Endocrine glands are responsible for producing/secreting hormones and releasing them directly into the blood from where they travel to tissues and organs throughout the body. Some examples of endocrine glands are the pituitary gland (it regulates homeostasis), the thyroid gland (It helps to regulate growth and metabolism) and the adrenal glands (they perform different functions at the endocrine and nervous level).
