Explanation

Guard cells regulate the opening and closing of stomata, controlling gas exchange and transpiration.

They surround the stomata and change shape in response to environmental conditions, opening or closing the stomata as needed.

Explanation

Saprotrophs are living organisms that derive their food from dead and decaying organic materials.

It playing a crucial role in decomposing organic matter and recycling nutrients in ecosystems.

Explanation

Horticulture is the branch of agriculture concerned with the cultivation of fruits, vegetables, nuts, seeds, and ornamental plants.

It involves the development of new varieties of plants, their breeding.

The improvement of their yield, quality, and resistance to diseases.

Explanation

• The loss of electrons and protons (H+ ions) is called oxidation.
• Oxidation is a chemical reaction that involves the loss of electrons or the addition of oxygen.
• Resulting in a change in the oxidation state of an atom, molecule, or ion.

Explanation

• Inhibitors are molecules that bind to enzymes and decrease their activity, thereby slowing down or preventing the biochemical reaction.
• Enzyme activity is not enhanced by inhibitors, but rather inhibited.

Explanation

• The correct answer is: Cell does not contain the hereditary material.

The cell theory postulates:

• All living organisms are made up of one or more cells.
• The cell is the fundamental unit of life.
• New cells are derived from pre-existing cells (biogenesis).

Explanation

The heartbeat refers to the rhythmic pulsation of the heart that pumps blood throughout the body.

It is a vital function that maintains blood circulation, supplying oxygen and nutrients to tissues and organs.

Explanation

Plasmolysis is the process by which a plant cell loses water and its cytoplasm shrinks, causing the cell membrane to pull away from the cell wall.

This can occur due to osmotic stress, such as when a plant is exposed to high concentrations of salt or sugar.

Explanation

The foundation of life is based on chemical processes and reactions that occur within living organisms.

These chemical reactions involve the building blocks of life.

Such as carbon, hydrogen, oxygen, nitrogen, and phosphorus.

They are combined in various ways to form biomolecules like carbohydrates, proteins, and nucleic acids.

Explanation

• The Fats is Lipid or Fatty acid, not Starch.
• Starch is a type of carbohydrate.
