Cell Basics
What's the basic unit of life?
A cell
This organelle contains the cell's DNA and controls many cell activities.
Nucleus
This structure surrounds a plant cell and provides extra support and protection.
Cell Wall
This is the movement of particles from an area of higher concentration to an area of lower concentration.
Diffusion
Plants use this process to convert light energy into chemical energy.
Photosynthesis
What are unicellular organisms?
Organisms made of only one cell
This organelle is often called the "powerhouse" because it helps produce usable energy for the cell.
Mitochondria
This organelle is found in plant cells and captures light energy.
Chloroplast
This type of diffusion involves the movement of water across a membrane.
Osmosis
This process allows cells to convert glucose into usable energy called ATP.
Cellular respiration
What is a multicellular organism?
An organism made of many cells
These structures make proteins for the cell.
Ribosomes
This green pigment helps plants capture light energy for photosynthesis.
Chlorophyll
This describes the difference in concentration between two areas.
Concentration gradient
This process can occur when cells break down food without enough oxygen.
Fermentation
What organisms do not have a nucleus and include bacteria?
Prokaryotes
This organelle breaks down waste and unwanted materials in the cell.
Lysosome
Name one major structure found in plant cells that animal cells do not have.
Cell wall or chloroplast
This type of transport requires the cell to use energy to move substances.
Active Transport
What is the waste product of yeast
carbon dioxide
These organisms have cells with a nucleus and include animals and plants.
eukaryotes
What organelles are shared by both prokaryotic cells and eukaryotic cells?
Cytoplasm, cell membrane, DNA, Ribosomes
A student observes a cell with a cell wall and chloroplasts. Is it more likely a plant cell or an animal cell?
plant cell
This type of transport does not require the cell to use energy.
Passive Transport
Waste products of bacteria
lactic acid
