2.3 Biology Exam Review

Front

What is an autotroph?

Back

An autotroph is an organism that produces its own food, typically through photosynthesis, using sunlight, water, and carbon dioxide. Examples include plants and some bacteria.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and instead consumes other organisms for energy. Examples include animals, fungi, and many bacteria.

Front

What is the purpose of cellular respiration?

Back

The purpose of cellular respiration is to release energy from food, which is used by cells to perform various functions.

Front

What are the main products of aerobic respiration?

Back

The main products of aerobic respiration are carbon dioxide and water.

Front

What is aerobic cellular respiration?

Back

Aerobic cellular respiration is a process that requires oxygen to break down glucose, producing energy (ATP), carbon dioxide, and water.

Front

What is anaerobic cellular respiration?

Back

Anaerobic cellular respiration is a process that occurs without oxygen, resulting in the production of energy (ATP) and byproducts like lactic acid or ethanol.

Front

What are the components of a stamen in a flower?

Back

The stamen consists of two main parts: the anther, which produces pollen, and the filament, which supports the anther.

Front

What is ATP and its role in cellular processes?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes, including muscle contraction and biochemical reactions.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.
