Explanation

Amoeba, Euglena, and Paramecium are all unicellular organisms.

They consist of a single cell that performs all the functions necessary for survival, such as movement, reproduction, and obtaining nutrients.

Explanation

The nucleus is the most important part of the cell as it controls all the activities of the cell, including growth, metabolism, and reproduction.

It contains the cell's genetic material (DNA) which regulates gene expression and directs protein synthesis.

Explanation

Cotyledons provide food to the embryo during seed germination.

It also protect the baby plant by being a part of the seed structure that safeguards the developing plant.

Cotyledons are the first leaves of a seedling.

It play a crucial role in the early stages of growth.

Explanation

The seed coat is called the testa.

It protects the seed from physical damage and prevents water loss.

Plumule is the young shoot.

Radicle is the young root that emerge from the seed during germination.

Explanation

The diaphragm is a muscle that separates the chest cavity (thoracic cavity) from the abdominal cavity.

It plays a key role in breathing by contracting and relaxing to allow air in and out of the lungs.

Explanation

The correct chemical equation for photosynthesis is:

6CO₂ + 6H₂O → sunlight/chlorophyll C₆H₁₂O₆ + 6O₂

This equation shows that carbon dioxide and water are converted into glucose and oxygen in the presence of sunlight and chlorophyll.

Explanation

The pinna is the outer part of the ear that collects sound waves and directs them into the ear canal.

From there, sound waves travel to the ear drum and further into the inner ear for processing.

Explanation

Asexual reproduction in plants is commonly referred to as vegetative propagation or vegetative reproduction.

It involves the formation of new plants from parts of the parent plant, like stems, roots, or leaves, without the involvement of seeds.

Explanation

In layering, a branch of a plant is bent down to the soil, partially buried, and encouraged to form roots, eventually growing into a new plant.

This method is often used for plants like strawberries and jasmine.
