Palisade Cell Function: Cellular Structure Quiz and Flashcards

Study Notes

Ciliated Cell

Lines air passages down to the lungs
Has tiny hairs called cilia
Functions to stop lung damage by sweeping mucus with trapped dust and bacteria back up the throat to be swallowed

Effects of Smoking

Causes cilia to die
Leads to mucus buildup, resulting in a smoker's cough

Palisade Cell

Found in the top of a leaf
Has a tall structure with a large surface area to catch as much sunlight as possible
Packed with chloroplasts to absorb sunlight
Functions to carry out photosynthesis to help make plant food

Phloem Cell

Composed of sieve tube elements and companion cells that are living
Functions to transport food substances (sugars) from leaves to other parts of the plant

Xylem Cell

Composed of hollow, non-living cells with lignified walls
Functions to conduct water and minerals from the root to the leaves of the plant

Nerve Cell

Extremely elongated (long) cells
Has many branches at both ends to connect to other nerve cells
Long axis (main branch) is covered in fat to prevent electrical impulses from affecting surrounding parts of the body
Functions to carry nerve impulses around the body

Root Hair Cell

Has a large surface area to absorb lots of water
Thin cell wall allows water to pass through easily
Does not contain chloroplasts, unlike other plant cells
Functions to absorb minerals and water

Description

Learn about the structure and function of ciliated cells, which line air passages and help prevent lung damage, and palisade cells, which are found in leaves and are responsible for absorbing sunlight. Test your knowledge of these important cell types!
