16
What is the fundamental unit of life?
cell
17
Who is the father of evolution?
Charles Darwin
18
Why are cells the fundamental of life?
because they are the smallest living organisms that can perform all the essential functions required for life.
19
What book did Charles Darwin write?
‘On the Origin of Species’
20
What is natural selection?
The process by which population of living organisms adapt and evolve over time in response to environmental pressures, resulting in the survival and reproduction of individuals with favorable traits
21
What is a cell theory?
It states that all living organisms are composed of cells, cells are the basic units of life, and all cells arise from pre-existing cells
22
Who founded cell theory?
Theodor Schwann and Matthias Jacob Schleiden
23
Why are cells small?
to maximize their surface area to volume ratio, which allows them to efficiently exchange materials
24
Who invented the microscope?
Hans and Zacharias Janssen
25
What is diffusion?
the movement of tiny particles from an area where there are lots of them to an area where there are fewer, until they are spread out evenly
26
Who coined the term “cell” looking at a piece of cork?
Robert Hooke
27
What are the three domains in life?
Archaea, Bacteria, and Eukarya
28
What’s the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells lack a true nucleus and membrane-bound organelles while eukaryotic cells have a true nucleus and membrane bound organelles
29
What is the plasma membrane made up of?
the plasma membrane is made up of a phospholipid bilayer with embedded proteins
30
What is a nucleus?
the structure in a cell that contains the chromosomes
31
What is mitochondria?
organelles in cells that produce energy for the cell
32
What are ribosomes?
small organelles that make proteins for a cell
33
What is Rough ER
a membraneous organelle that has a large surface area covered in ribosomes
34
What is Smooth ER
helps make and process lipids and helps detoxify drugs and alcohol
35
What are the three cytoskeletal structures?
microtubules, actin filaments, and intermediate filaments.
36
What are microtobules?
hollow tubes that are part of the cytoskeleton of eukaryotic cells
37
what are actin filaments?
solid protein rods that make up part of a cell's cytoskeleton
38
what are intermediate filaments?
proteins that make up a major part of the cytoskeleton in animal cells.
39
what is the Golgi apparatus?
a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
