HESI A2 Biology Exam Questions with
Accurate Answers
Oxygen requirement - ✔✔*Aerobic Respiration*- Yes, always
*Anaerobic Respiration*- No, never
Waste products - ✔✔Aerobic respiration - Carbon dioxide & water
Anaerobic respiration - Carbon dioxide and ethanol
Efficiency in releasing energy from glucose - ✔✔Aerobic respiration - Very efficient ( most of
the energy is released from glucose )
Anaerobic respiration - Less efficient ( some energy locked in ethanol not released )
Some energy released as heat - ✔✔Aerobic respiration - Yes
Anaerobic respiration - Yes, but less than aerobic
Plant cells - ✔✔Cellulose cell wall surrounds the cell membrane
Plant cells - ✔✔Plastids are present - especially a green pigment called chlorophyll
Plant cells - ✔✔Most plants do not exhibit movement of locomotion
Plant cells - ✔✔Keep growing throughout their life and are localized in the apical meristem
Plant cells - ✔✔Manufacture their own food by photosynthesis
,Plant cells - ✔✔Sense organs and nervous system absent
Animal cells - ✔✔Cell wall is absent in animal cells
Animal cells - ✔✔Chlorophyll is absent in animal cells
Animal cells - ✔✔Vacuoles are usually absent
Animal cells - ✔✔Most animals exhibit movement of locomotion
Animal cells - ✔✔Growth stops after maturation but body cells are replaced periodically.
Growth is uniform and proportionate.
Animal cells - ✔✔Cannot make their own food. They depend directly or indirectly in plants for
their food
Animal cells - ✔✔Well-developed nervous system
Muscle cells - ✔✔These are usually cylindrical or spindle-shaped. They cause some parts of the
body to move by contracting.
Epithelial cells - ✔✔They form a layer and protect the cells below them from injury.
Red blood cells - ✔✔These cells which are shaped like disco do not have nucleus. They bring
oxygen to different parts of the body.
, White blood cells - ✔✔These cells have a nucleus. They can change their shape. They kill or
engulf microorganisms such as bacteria which enter the blood stream.
Nerve cells - ✔✔These cells are very long. They carry information (impulse) from one part of
the body to another.
Sperm - ✔✔This cell has a long tail which helps it to move about. It can unite with an egg cell
(ovum) to form a baby.
Ovum (egg cell) - ✔✔This is the largest cell in woman's body. It does not move on its own. It
develops into a baby if its united with a sperm.
Prophase - ✔✔*1st step of mitosis* During prophase, the chromosomes are visibly separate
and each duplicated chromosome has two noticeable sister chromatids. ( • Prophase: the
chromosomes condense )
Prometaphase - ✔✔*2nd step of mitosis* In prometaphase, the nuclear envelope begins to
disappear and the chromosomes begin to attach to the spindle that is forming along the axis of
the cell. (• Prometaphase: the nuclear envelope disintegrates and microtubules enter the
nucleus)
Metaphase - ✔✔*3rd step in mitosis* In metaphase, the chromosome align along the center of
the cell in what is called the metaphase plate. ( • Metaphase: the microtubules attach to the
center of each chromosome and start to pull each chromosome to opposite ends of the cell )
Anaphase - ✔✔*4th step in mitosis* Anaphase begins when chromosomes begin separating. In
this phase, chromatids are considered separate chromosomes. ( • Anaphase: The proteins that
bind chromatids are cleaved and the two daughter chromosomes are fully pulled to opposite
ends of the cell )
Telophase - ✔✔*5th and last step in mitosis* In the final phase, telophase, chromosomes
gather on either side of the now separating cell. This marks the end of mitosis. ( • Telophase:
