Explanation

Cell wall is not a part of animal cells; it is found only in plant, fungal, and bacterial cells.

Animal cells have a cell membrane, cytoplasm, and vacuole (though smaller than in plant cells).

Explanation

• Self-Pollination is the transfer of mature pollen grains from the anther of one flower to the stigma of the same flower or another flower of the same plant.
• This means that the pollen is transferred within the same plant, allowing for fertilization to occur without the involvement of another plant.

Explanation

The auditory nerve (also called the cochlear nerve) transmits sound signals from the ear to the brain.

It plays a direct role in the sense of hearing.

Explanation

Centrioles are typically found in animal cells, not in most plant cells.

Plant cells do have chloroplasts, mitochondria, and a cell membrane.

Explanation

• The male reproductive part of a flower is called the Stamen.

It consists of two parts:

1. Anther (produces pollen grains)
2. Filament (supports the anther)

Explanation

Snails are mollusks, belonging to the phylum Mollusca.

They typically have a soft body and, in many cases, an external shell.

Explanation

When the left ventricle contracts, it pumps oxygenated blood into the aorta.

This blood is then distributed to the entire body through systemic circulation.

Explanation

The average weight of an adult human brain is about 1300 to 1400 grams.

It makes up around 2% of the total body weight but consumes about 20% of the body's energy.

Explanation

Genes are units of heredity located on chromosomes that control the traits passed from parents to offspring.

They determine physical and biochemical characteristics in all living organisms.

Explanation

Lungs remove carbon dioxide, a waste product of cellular respiration.

It is carried by the blood to the lungs and exhaled out of the body.
