NS- Other Cells Flashcards
Ciliated Epithelial Cell
Animal cell.
Found in the lining of the nose, windpipe and lungs.
It’s function it to carry dust particles and germs away from these areas to keep them heathy.
Cells have tiny hairs calls cilia which regularly brush mucus away to move particles of dust and germs. These cells have many mitochondria to make energy for cilia to move.
Sperm Cell
Animal cell.
Found in the testes of the male.
It’s function is to carry heritable characteristics (DNA) to the egg when fertilization occurs.
It has a tail to swim up the vagina to find the egg cell in the Fallopian tube. They have many mitochondria to give it energy needed to swim. Special chemicals in the head help dissolve the ovum’s membrane. It contains the DNA from the father.
Root Hair Cell
Plant cell.
Found on the surface of plant roots.
It’s function is to increase the root’s surface area to absorb more water and minerals.
They have long, thin parts. These parts reach outwards into the soil to increase the surface area of the root in contact with the soil. They also have very thin cell walls to allow water and nutrients to pass from the soil into the root.
Palisade Cell
Plant cell.
Found in the upper surface of a leaf.
Its function is to trap sunlight energy during photosynthesis.
They are long and shaped like cylinders. They have many chloroplasts, which contain green pigments called chlorophyll to trap the sun’s energy for photosynthesis. Each cell has a large surface area to increase the area for gaseous exchange.
Red Blood Cells
Animal cells.
Found in the blood of animals.
Its function is to carry oxygen from the lungs or parts of the body.
They have found, flat shapes and are thicker at the edges than in the middle. They are very flexible so that they can squeeze though thin blood vessels without breaking. They contain a red pigment called hemoglobin, which carries oxygen.
White Blood Cell
Eats harmful bacteria.
It is able to change its shape and move about, even through the walls of blood vessels, into the surrounding tissues.
Food-Conducting Cell
Plant cell.
Long cells are joined end to end, and there are holes in the walls where they meet. Through these holes, the cytoplasm of one cell is in contact with the next. Dissolved food is thought to pass through the holes during its journey to the stem.
Muscle Cell
Thee longs cells can make themselves shorter. When they all shorten at once, the muscle layer contracts.
Nerve Cell
Conducts electrical impulses along the fiber.
Consists of hundreds of fibers bound together. The fibers may be very long.
