what are the basic components of cell
Answers
Answer:
THE THREE MAIN COMPONENTS OF ANY PLANT OR ANIMAL CELL ARE:
PLASMA MEMBRANE/ CELL MEMBRANE. Structure- a bilipid membraneous layer composed of proteins and carbohydrates. ...
CYTOPLASM. ...
NUCLEUS. ...
Explanation:
. PLASMA MEMBRANE/ CELL MEMBRANE
Structure- a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like.
Function - the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out). It protects the cell and provides stability.
Proteins are found embedded within the plasma membrane, with some extending all the way through in order to transport materials.
Carbohydrates are attached to proteins and lipids on the outer lipid layer.
2. CYTOPLASM
Structure - The jelly-like substance composed of mainly water and found between the cell membrane and nucleus. The cytoplasm makes up most of the "body" of a cell and is constantly streaming.
Function - Organelles are found here and substances like salts may be dissolved in the cytoplasm.
3. NUCLEUS
Structure - The largest organelle in the cell. It is dark and round, and is surrounded by a double membrane called the nuclear envelope/membrane. In spots the nuclear envelope fuses to form pores which are selectively permeable. The nucleus contains genetic information (DNA) on special strands called chromosomes.
Function - The nucleus is the "control center" of the cell, for cell metabolism and reproduction.
THE FOLLOWING ORGANELLES ARE FOUND IN BOTH PLANT AND ANIMAL CELLS.
Answer:
the basic components of a cell are as follows:
1. nucleus: acts like a brain for the cell, controls the cell division and what is entering and exiting from the cell.
2. cytoplasm: jelly-like substance . which is around the cell,Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.
3. endoplasmic reticulum: The endoplasmic reticulum is the largest, membrane-bound organelle found in cells , It is a highly dynamic organelle that radiates from the nuclear envelope towards the plasma membrane.
4. mitochondria: called as the powerhouse of the cell, mitochondria processes nutrients: breaks them and creates energy for the cell.
5. cell membrane and cell wall: found in animal cell and plant cell respectively; provides a boundary for cells.
6. ribosomes: Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
7. lysosomes: destructive enzymes; break down/ destroy foreign particles.
8. chromosomes: carry the genes of the parent cell.
9. golgi body: A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
