Question

Gastrulation involves the movement of cells that help the embryo attain new shape and morphology. These cell movements are called

• A. tropic movements
• B. locomotory movements
• C. morphogenetic movements
• D. peristaltic movements

Answer 1

The correct option is C morphogenetic movements

Gastrulation involves the movement of cells that help the embryo attain new shape and morphology. The three germ layers formed during gastrulation give rise to different organs and tissues. The cell movements are called morphogenetic movements. These movements play an important role in the development of the embryo.
If a plant shows movement in response to certain stimuli present in the environment, it is called tropic movement.
When movement in an organism causes the organism to move from one place to another, it is called locomotory movement.
The passage of food inside the digestive tract is facilitated by a type of movement called peristalsis or peristaltic movement. It is a series of wavelike contractions that help the food travel in the digestive tract.
