BIO 253 STUDY GUIDE 2026 VERIFIED
QUESTION SET AND SOLUTIONS
◉ Endocytosis.
Answer: process by which a cell takes material into the cell
Pinocytosis
Phagocytosis
◉ What is hypotonic.
Answer: A solution with lower salt concentration than in the cells
(cells burst) MORE WATER THAN IN CELL
◉ What is a hypertonic solution?.
Answer: The solution has a higher solute concentration than the cell
so water moves out of the cell.
Cell shrinks
◉ Abdominal regions.
Answer:
,◉ Abdominal quadrants.
Answer:
◉ Ionic bond.
Answer: Donating electrons, attraction of atoms and cannot separate
◉ Covalent bonds.
Answer: Strongest bond
Bonds created by sharing electrons with other atoms.
◉ catobolism.
Answer: energy releasing process that breaks down large molecules.
◉ Anabolism.
Answer: Building molecules up
◉ Mitochondria.
Answer: Powerhouse of the cell, organelle that is the site of ATP
(energy) production
, ◉ Lysosome.
Answer: cell organelle filled with enzymes needed to break down
certain materials in the cell
◉ Nucleus.
Answer: A part of the cell containing DNA and RNA and responsible
for growth and reproduction
◉ Nucleolus.
Answer: Found inside the nucleus and produces ribosomes
◉ Golgi apparatus.
Answer: A system of membranes that modifies and packages
proteins for export by the cell
◉ Centrioles.
Answer: Organelle used for cell division form spindle fibers to
evenly split DNA
◉ Why do cells divide.
Answer: For growth and repair
◉ Four main biomolecules.
