Cell Specialization in Animals
Definition of a specialized cell.
The shape of a red blood cell
Bi-concave disc shape
This specialized cell allows plants to absorb more water and minerals it needs to keep alve
root hair cell
The number of tissues found in Man.
4, epithelial (covers and protects), connective (supports and binds), muscle (allows movement), and nervous (controls and communicates)
Mention 1 benefit of cell specialization
They can focus on fewer tasks at once and do the work more efficiently while saving energy by not performing other tasks
They can have a specialized structures and metabolism
As they do one (or few) things all the time, they evolve faster in that particular tasks
This animal cell is responsible for the transport of Oxygen
red blood cell
Name of the protein that helps red blood cells carry oxygen; gives RBC its red color
hemoglobin
This type of cell is dead (without organelles or cytoplasm) allowing free passage of water
xylem cell
Shape of guard cells
kidney bean shape
The order of cell organization
Cells --> tissues --> organs --> organ systems
This specialized cell has an axon that is covered with a fatty sheath
nerve cell
True or False: Nerve cells are short so that nerves can run to and from different parts of the body to the CNS
False
This specialized cell allows gases, such as carbon dioxide and oxygen, into the leaf cells
guard cell
This type of tissue creates protective boundaries that cover the outer surfaces of the body, line internal cavities and passageway, as well as form certain glands.
epithelial tissue
Name of the component that allows the sperm cell to swim
flagellum/flagella
A sperm cell is filled with this organelle that releases energy in order for the cell to swim
mitochondria
What kind of nucleus do both an egg cell and sperm cell have?
haploid cell
This specialized cell helps transport dissolved sugars and amino acids, and are living
phloem cell
This type of plant tissue does not have chloroplasts and is known as the plant epidermis.
dermal tissue
The name of the tiny hairs found on the top of ciliated cells
cilia
What happens to the cell membrane after the fertilization of a single sperm?
The cell membrane changes its shape which allows no other sperm to enter
2 places where ciliated cells can be found
airways and oviducts
Name of the opening that the guard cells function as a protective layer to facilitate in the gaseous exchange between the plant cells
stomata/stoma
This type of tissue is known as the plumbing system of the plant.
vascular tissue
Name of the substance that thickens the walls of xylem and phloem cells, strenthening the tubes
lignin
