Biology Semester 1

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What are ionic bonds?

Back

Ionic bonds are chemical bonds formed through the transfer of electrons from one atom to another, resulting in the attraction between positively and negatively charged ions.

Front

What charge does a proton have?

Back

A proton has a positive charge.

Front

What is the role of electrons in chemical bonding?

Back

Electrons are involved in chemical bonding; they can be transferred (ionic bonds) or shared (covalent bonds) between atoms.

Front

What is the difference between a plant cell and an animal cell?

Back

Plant cells have a cell wall, chloroplasts, and large vacuoles, while animal cells do not have these structures.

Front

What is the significance of biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, and it is crucial for ecosystem resilience, stability, and the provision of ecosystem services.
