Gravity
Plant roots always grow downward because specialized cells in root caps detect and respond to gravity. This is an example of a tropism. A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism.
Answer:
Explanation:
This question appear wrong. Cells do not divide other cells as cells have the ability to undergo individual cell division as seen in cell cycle. However, there are some factors that could lead to increased cell division; factors such as cancer and viral infection can lead to increased division of certain cell types.
There is also a cell organelle present in mammalian cells that facilitates the division of a cell - this organelle is known as centriole. Centrioles do this by assisting in the separation of chromosomes during the mitotic phase of the cell cycle.
The correct answer is (C) Insects get food from flowers and help the flowers reproduce.
Mutualism is a condition where both the members get benefit of living on each other. In this condition the the insects gets food in the form of nectar and helps the flower to reproduce. It is a condition in which one organism (insect) is helping the plant to reproduce and as a result of this, the insect is getting food from the flower.
