All for Feasib

NUCLEUS- It is the central part of cell, control and directs all activities of the cell.

CYTOSKELETON- Long threadlike structure which are made of molecules of Protein and DNA.

RIBOSOME- Small granular structure some are attached to the membrane, some are float freely in the cytoplasm.

CENTRIOLE- Duplicate during Interphase & Prophase, control the arrangement of microtubules during cell division.

CELL WALL- Responsible for making the cell rigid, gives plant a definite shape.

NUCLEAR MEMBRANE- Consists of Double layer of fats, protein & associated with short chains of sugar, has many holes/pores, it covers the nucleus.

GOLGI APPARATUS- Flattened sacs, modifies proteins that are synthesize & packaged in the ER, make sugar & stores together with proteins & lipids in secretory vesicle.

LYSOSOMES- Membrane bounded bag produced by RER & golgi apparatus, digest nutrients & broken down organelles.

CELL MEMBRANE- Double layered membrane enclosing the cell,permeable & limits exchange of H2O & some substances.

CHLOROPLAST- Contain green pigment (chlorophyll) w/c/ is used to convert light energy to ATP.

CYTOPLASM- Semi-liquid substance w/c the organelles are suspended (clear, jelly like fluid)

NUCLEAR SAP- Fluid part of nucleus, it is also called the nucleoplasm or karyoplasm.

MITOCHONDRIA- Commonly know as the powerhouse of the cell, the place where chemical energy (glucose) is converted to ATP.

ENDOPLASMIC RETICULUM- Extensive membrane system, synthesize & package proteins w/c are sent to be to synthesize in golgi apparatus.

SER- Branching canals & act as calcium ions reservoir in skeletal system.

RER- Stacks of sheetlike flattened sacs w/ ribosomes that attach the cytoplasmic surface of stacks.

Classification of Cytoskeleton

Microtubules:

1. Skeleton of cells

2. Motility

3. Chromosome Movement

4. Disposition & movement of...
