A plant cell includes a Cell Wall, Cell Membrane, Cytoplasm, Nucleus, Chloroplast, Mitochondria, Vacuole. Each of these parts play unique roles in plant growth and survival, with tasks ranging from providing structure and protecting the cell, to performing photosynthesis and producing energy.
A plant cell is the structural and functional unit of plants that performs various biological functions. The cell has many parts, each with unique functions.
1) Cell Wall: This is the outermost layer providing structure, support and protection to the cell.
2) Cell Membrane: It controls the movement of substances in and out of the cell.
3) Cytoplasm: It contains all the organelles and is where most cellular activities occur.
4) Nucleus: It controls cell activities and contains the genetic material DNA.
5) Chloroplast: This is where photosynthesis takes place.
6) Mitochondria: They produce energy for the cell through respiration.
7) Vacuole: It stores water, nutrients and waste products.
Every part of the plant cell plays a crucial role in plant growth and survival.

C. pendular movements of the gastrointestinal tract
D. waves of muscular contractions that propel contents from one point to another
Answer:
Option (D).
Explanation:
Peristaltic movements are involuntary movement occur due to the longitudinal and circular muscle.Peristaltic waves helps in the passage of food from one point to another during the process of digestion.
Peristaltic waves occur mainly due to muscular contraction. These contractions propel the contents from one location to another. These waves occur in stomach, intestine and esophagus.
Thus, the correct answer is option (D).
Peristaltic waves are waves of muscular contractions that propel contents from one point to another. Therefore, the option is D.
The waves of muscular contractions known as peristaltic waves are responsible for moving materials from one location to another. They are in charge of the transportation of food through the digestive system from beginning to end.
Therefore, peristaltic waves are waves of muscular contractions that propel contents from one point to another
