a membraneous organelle that has a large surface area covered in ribosomes
5
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

7
What is a biome?
a group of ecosystems having the same climate and dominant assemblages of plants and animals
8
What is the fourth step of the scientific method?
Formulate a hypothesis
9
Who is the father of evolution?
Charles Darwin
10
What is the third step of the scientific method?
Research the topic
11
What is an ecosystem?
a community of living organisms and their environment that interact with each other
12
What book did Charles Darwin write?
‘On the Origin of Species’
13
Why are cells the fundamental of life?
because they are the smallest living organisms that can perform all the essential functions required for life.
14
What is the fundamental unit of life?
cell
15
What are the three cytoskeletal structures?
microtubules, actin filaments, and intermediate filaments.
16
Who invented the microscope?
Hans and Zacharias Janssen
17
What is an organism
any living thing
18
What are the three domains in life?
Archaea, Bacteria, and Eukarya
19
Why are cells small?
to maximize their surface area to volume ratio, which allows them to efficiently exchange materials
20
What is mitochondria?
organelles in cells that produce energy for the cell
21
What is the first step of the scientific method?
Make an observation
22
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
23
what are actin filaments?
solid protein rods that make up part of a cell's cytoskeleton
24
What are microtobules?
hollow tubes that are part of the cytoskeleton of eukaryotic cells
25
What are ribosomes?
small organelles that make proteins for a cell
26
What is Smooth ER
helps make and process lipids and helps detoxify drugs and alcohol
27
What is a biosphere?
the part of Earth where life exists, including the land, water, and air
28
What is an organ system?
a group of organs that work together to perform a specific function within an organism
29
What is the second step of the scientific method?
Ask a question
30
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
31
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.
32
What is a community?
a group of different species of living organisms that interact with each other in a shared area
33
What is the sixth step of the scientific method?
Analyze the data
34
What is a nucleus?
the structure in a cell that contains the chromosomes
35
What is the plasma membrane made up of?
the plasma membrane is made up of a phospholipid bilayer with embedded proteins
36
What is the fifth step of the scientific method?
Conduct an experiment
37
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
38
What is population?
the number of people living in a certain place
39
what are intermediate filaments?
proteins that make up a major part of the cytoskeleton in animal cells.
