Blood is considered a tissue because blood -
flows inside arteries and veins
is necessary to carry oxygen and nutrients to the cells
is pumped from the heart and is carried to the cells through arteries
is composed of red and white blood cells working together and having specific functions
The eukaryotic organism described above should be classified as -
an animal
a bacterium
a fungus
a plant
How is the prokaryotic bacterium in the diagram different from a eukaryotic cell?
It has ribosomes to make proteins.
It stores its genetic information in DNA.
It has no membrane-bound nucleus.
It has a cell membrane.

enzymes
organs
other cells
DNA
What is the purpose of the flagellum?
circulation
catching prey
movement
attachment

nucleus
Golgi apparatus
mitochondrion
endoplasmic reticulum

the nucleus
the golgi apparatus
the mitochondrion
the smooth endoplasmic reticulum
