Biology Microscope and Cells Test
What does a Eukaryotic cell have?
A NUCLEUS, many organelles
Centrioles
Cell division, ONLY in animal, reproduction
series of channels throughout the cell is...
Endoplasmic Reticulum
What does a prokaryotic cell have?
NO NUCLEUS. cell membrane, cytoplasm, DNA, ribosomes
Is DNA always inside a nucleus?
NO!!
IMPORTANT: Cell Membrane
Outside very cell, controls what goes in/out of cell, excretion, regulation, transport
Chloroplasts
Photosynthesis, ONLY in plant, nutrition
Cell Wall
Provides structure, only in plant
What is the cell theory?
all life is made of cells, all cells come from other cells.
The respiratory system of an elephant functions in a similar way to which organelle in a single celled organism?
cell membrane
ALL cels have what 4 things?
cell membrane, cytoplasm, ribosomes, DNA
What does an animal cell have that plant cells do not?
centrioles
Endoplasmic Reticulum
channels. transport protein
a difference between plant and animal cells is that animals dont have ____________>
chloroplasts
What does a plant cell have that animals do not?
chloroplasts, cell wall, large central vacuole
Lysosomes are directly responsible for what?
digestion of bacteria
Lysosome
digests, nutrition,
IMPORTANT: Nucleus
large circle with black circle inside, control center, contains DNA or genetic material
IMPORTANT: Cytoplasm
liquid, transport, allows materials to move around
Where does cellular respiration take place?
mitochondria
ORGANIZE from least complex to most. organ call organism organelle tissue
organelle, cell, tissue, organ, organism
Golgi
packages and exports materials, transport
IMPORTANT: Mitochondria
powerhouse of cell, makes ATP, respiration, squiggly line
IMPORTANT: Ribosome
small black dots, protein and synthesis
IMPORTANT: vacuoles
storage, regulation
DEFINE: organelle
structure inside a cell that performs a specific function
What are the exceptions of the cell theory?
the first cell, virtues, mitochondria and chloroplasts
In single celled organisms, materials are primarily found in
vacuoles - STORAGE PLACES
Which organism is considered an exception to the cell theory because it has a noncellular structure?
virus
