biology
This pigment gives plants their green color.
its chlorophyll!
this is the basic unit of life.
cells.
The largest organ in the human body.
skin
Name two major types of organisms that are made of eukaryotic cells.
Plants, animals, fungi, and protists.
What is the defining feature that distinguishes a eukaryotic cell from a prokaryotic cell?
A eukaryotic cell has a membrane-bound nucleus, while a prokaryotic cell does not.
This process uses sunlight to turn carbon dioxide and water into food for a plant.
photosynthesis
Plant cells have this outer layer for structural support.
The cell wall
Often called the "powerhouse of the cell," this organelle is the site of cellular respiration to produce ATP.
mitochondria
What do lysosomes do in a eukaryotic cell?
They break down waste materials and cellular debris using digestive enzymes.
The DNA forms a what?
A single large coil, commonly known as a circular chromosome.
What organelle is found in plant cells but not animal cells and is responsible for photosynthesis?
chloroplasts
What is the function of the nucleus in a cell?
The nucleus contains the cell's DNA and controls its activities.
Jelly fishes have hearts. True or False?
Unlike prokaryotes, eukaryotic cells have these complex, membrane-enclosed structures.
Where is the DNA found in prokaryotic cells?
DNA is found free within the cytoplasm of the cell in an irregular region called neucleoid.
This is the period of the cell cycle when a eukaryotic cell grows, duplicates its DNA, and prepares for division.
interphase
Where does respiration take place in a cell?
Respiration occurs in the mitochondria
teeth! (tooth enamel)
Unlike prokaryotes, eukaryotic organisms can be either unicellular or this type of organism, composed of many cells.
multicellular
Are prokaryotes bigger or smaller than eukaryotic cells?
much smaller
What is the specific phase in mitosis where replicated chromosomes line up at the center of the cell?
metaphase
This large organelle is found in plant cells and helps maintain turgor pressure and store water and nutrients
central vacuole
Name one example of a prokaryote and one example of a eukaryote
Bacterium
does it matter how big a eukaryotic cell is?
NO!
Key features of prokaryotes.. (name one)
1- The diagram of a typical prokaryote (bacteria) is shown to the right
2- It shows the absence of both a membrane-bound organelles.
