|
organelle
|
ORGANELLES are tiny cell structures, which , carry out specific functions within the cell.
|
|
|
cell wall
|
The cell wall is a rigid layer of nonliving material that surrounds the cells of plants and some other organisms. ( A plants cell wall helps to protect and support the cell.
|
|
|
cell membrane
|
The cell membrane controls what substances come into and out of a cell.
|
|
|
nucleus
|
The nucleus is the cells control center, which directs all the cells activities.
|
|
|
nuclear envelope
|
The nucleaus is surrounded by a membrane called the NUCLEAR ENVELOPE. Just as an envelop protects the letter, the nuclear envelope surround the nucleus.
|
|
|
chromatin
|
Cells floating directlyahead in the nucleus. These strands called CHROMATIN , contain genetic material, the instruction for for directing the cells functions.
|
|
|
nucleolus
|
The nucleuolus is where the ribosomes are made. ( Ribosomes are the organelles where proteins are produced.
|
|
|
cytoplasm
|
Cytoplasm is the region between the cell membrane and the nucleus. The fluid in cytoplasm is constantly moving. ( Many cell organelles are found in the cytoplasm.)
|
|
|
mitochondria
|
Mitochondria are known as the 'powerhouse' of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.
|
|
|
endoplasmic reticulum
|
the endoplasmic reticulum's passageways carry proteins and other materials frome one part of the cell to another
|
|
|
ribosomes
|
Ribsomes dunction as factories to produce proteins.
|
|
|
Golgi bodies
|
The golgi bodies receive proteins and other newly formed materials from the endoplasmice reticulum, package them, and destribute them to other parts if the cell.
|
|
|
Choroplasts
|
Choroplasts capture energy from the sunlightand use it to produce food for the cells.
|
|
|
Vacuoles
|
Vacuoles are the storage areas of cells
|
|
|
Lysosomes
|
Lysosomes are small, round structures conatining chemicals that break down certain materials into cells.
|
|
|
Specialized Cells
|
In many-celled organisms, cells are often quite different from each other and qnd are specialized to preform specific funtion.
|
|
|
Tissue
|
Tissue is a group of similar cells that work together to perform a specific function.
|
|
|
Organs
|
An organ like your brain, is made out of different kinds of tissues that function together.( In addition to the nervous tissue, the brain contains different types of tissues that support and protect it.
|
|
|
Organ System
|
The organ system is a group of organs that work together to perform a major function.
|
|
|
Bacteria Cells
|
While a bactreia cell does have a cell wall and cell membranes, it doesn't contain a nucleus. The bacterial cell's genetic material.
