Growth
|
|
|
The cells ability to increase the # of organisms. some cells reproduce more easily.
|
Reproductoin
|
|
|
**The ability to adjust to external changes. It's very important. Ex. Temp changes will affect homeostatis.
|
Adaptability
|
|
|
The ability to respond to a stimulus. Ex. nerve & muscle tissue.
|
Irritability/Excitibility
|
|
|
the ability of a cell to change its shape. Impt.for movement.
|
Contractility
|
|
|
Waste being release. A cells ability to release its waste if not toxins cause problems
|
Excretary
|
|
|
The cells ability to release useful materials. Ex. Saliva.
|
Secretory
|
|
|
The ability of a cell to transmit an impulse. Ex. Muscle & Nerve Cells
|
Conductivity
|
|
|
The ability of a cell to carry out all the chemical reaction that is necessary for the survival of the living organisms.
|
Metabolism
|
|
|
2 types of metabolism
|
Catabolism
Anabolism |
|
|
Destructive or breaking down complex substances are broken down into simpler substances and causes a release of energy. Ex. Digestion
|
CATABOLISM
|
|
|
Buidling up. Simple substanced and make them more complex. Uses energy Ex. Cell Reproduction (Mitosis)
|
ANABOLISM
|
|
|
Little Organs
|
Organells
|
|
|
Outermost boundry of the cell. Thin delicate membrance that surrounds every cell.
|
Cell Membrane
|
|
|
Function of the cell membrane is?
|
Protection
|
|
|
The cell membrane is picky - it only allows certain things to go in. Its called?
|
Semi-Permeable (Selectively Permeable)
|
|
|
The control center of the cell. Its governs all the activities of the cell.
|
Nucleus
|
|
|
Major role in cell reproduction/division.
|
Centrioles
|
|
|
The primary fluid inside the cell membrane & outside the nucleus
|
Cytoplasm
|
|
|
Cytoplasm Components
|
Na, CA, K, Iron and Iodine
|
|
|
Plays a role in water balance in and out of the cell
|
Calcium
|
|
|
Important in trasporting O2 in the body cells
|
Iron
|
|
|
Important cytoplasm component in regulating metabolism
|
Iodine
|
|
|
Produce protein in the cell. Essential for cell reproduction and growth
|
Ribosomes
|
|
|
The transporation system within the cytoplasm
|
Endosplasmic Reticulum
|
|
|
Does not have ribosomes attached to it.
|
Smooth E.R.
|
|
|
The suicide beds.Sacs contain digestive enzymes. When the cell dies these powerful enzymes breakdown whatever remnants need to be removed and excreted by the body.
|
Lysosomes
|
|
|
cellular energy
|
ATP - immediate source of energy
|
|
|
Powerhouse of the Cell. Small glandular structures that provide cellular energy
|
Mitochondrion
|
|
|
Layers of membrane that package and enclose susbstances that are excreted from the cell. It's like a packaging plant
|
Golgi Bodies/Golgi Apparatus
|
|
|
Small hairlike extension that sweek foreign substances across.
|
Cilia
|
|
|
Tail of the sperm cell. This is the only one that has flagella.
|
Flagella
|
|
|
These are only found on nerve cells.
|
Myelin Sheath & Neurillema
|
|
|
Neurillema are only found in some ? cells. Its purpose is to allow for repair on a nerve cell do not regenerate.
|
Peripheral Nerves
|
|
|
What are the 2 types of cell reproduction?

Mitosis
Meiosis |
|
|
Which reproduction is essential for growth and repair of tissues?
|
Mitosis

|
|
Which cell reproduction has 46 chromosomes and will divide to form 2 identical cells each with 46 chromosomes
|
Mitosis
|
|
|
The 5 phases of Mitosis are?
|
Intraphase, Prophase, Metaphase, Anaphase and Telaphase.
