Cell Modification Flashcards
is a process that occurs after cell division where the newly formed cells are structurally
Cell Modification
-are specialized plant cells that absorb dissolved minerals and wate from the ground.
Root cells
Root cells grow in long lengths called (?)in order to increase the surface area of the root system. This also helps anchor the play.
Root Hairs
Xylem and phloem Cells are also known as?
Vascular tissues
- transport water from the roots in the upward direction.
Xylem
- transport nutrients in both directions to reach all parts of the plant.
Phloem
-Along the bottom of the leaf, guard cells open and close to allow the transfer of grass with the atmosphere as well as the transpiration of water
Guard Cells
- Specialized cells found in animals that transport oxygen throughout the body since transport is their primary function, they do not need a nucleus.
Red Blood Cells (4 months / 120 days)
- are long, fibrous cells that have the ability to contract. They allow animals to move and allow their organs to function in circulation as well as digestion.
Muscle cells
- are the cells that ling the outside. as well as the inside, of your body They are cells that make up your skin. Skin Epithelium is acually located just below the surface of your skin
Epithelial cells
(responsible for making new cells)
Epithelial cells
-The apical surfaces of epithelial cells are modified in certain areas in order to facilitate movement of substances.
Apical Modifications
- are membrane-covered extensions of the entire apical surface. They beat in waves, often moving a surface coat of mucus I trappes materials.
Cilia
- are also concerned w/movement. Spermatozoa, derived from seminiferous epithelia, are the only flagellated human cells
Flagella
Plasma-membrane - covered extensions of the cell surface. Their cores are composed of parallel actin microfilaments,
Microvilli
