Cell Basics
What jelly-like fluid fills the cell and holds organelles?
Cytoplasm
What is the smallest level of organization in living things?
Cell
A living thing made of one cell.
unicellular
All living things are made of ___?
Cells
What is the art style that uses dots to form a picture?
Pointillism
The tiny structures inside cells that perform functions. What is it?
organelles
A group of similar cells working together.
Tissue
A living thing made of many cells
multicellular
List 3 characteristics all living things share.
Organization, Growth and Development, Reproduction. Response to Stimuli, Use of Energy, Maintaining Homeostasis
What is the start of a Plant
Seed
What theory says all living things are made of cells, and how many principles are there.
Cell theory and 3 principles
A group of organs that work together to perform a function.
Organ system
A cell without a nucleus
prokaryotic cell
Why is it important that living things maintain homeostasis?
It keeps internal conditions stable for survival.
The jelly-like substance that holds organelles and allows movement inside the cell.
Cytoplasm
The job a cell takes on to perform a specific function.
Cell differentiation
The complete living thing made of many systems.
Organism
A cell with a nucleus and organelles.
Eukaryotic cell
What is the difference between structure and function in biology?
Structure is how something is built, and function is what it does.
A structure found in plant cells helps maintain shape, supports the cell, and prevents it from harm.
Cell wall
The person who studies cells and tiny life forms
Microbiologist
Place these in order from simplest to most complex: organ, tissue, cell, organism, organ system
cell → tissue → organ → organ system → organism
What is cell differentiation and why is it important?
It’s when cells become specialized to do different jobs, allowing complex organisms to function.
What do microbiologists study, and why is it important?
They study microscopic life (like cells, bacteria), helping us understand health and disease.
A microbiologist observes two cells: one has a nucleus, and one doesn't. What are they inferred?
The one with a nucleus is eukaryotic and the one without is prokaryotic.
