List the organelles found in both animal and plant cell
Cell membrane Nucleus Mitochondria Endoplasmic reticulum Ribosomes Golgi bodies
What is the cell membrane made out of
Phospholipids and proteins
CELL MEMBRANE How is the structure and function of the cell membarne exaplined
Its explained by. The fluid mosaic model
CELL MEMBRANE What do phospholipid form what is found embedded between the phospholipid molecules
The phospholipids form a double row or ‘bilayer’. protein molecules are found embedded between the phospholipid molecules
CELL MEMBRANE is its a living or on living layer and what does its do
it is the outer living component of cells that encloses the cytoplasm
What is the cell membrane also known as
plasma membrane or plasmalemma
Golgi body what do they secrete
they package and secrete cellular products such as enzymes and hormones
NUCLEUS what is this known as
The controlcenter of the cell
NUCLEUS What su the nucleus surrounded by
A double membrane surrounding the nuclear material called nuclear membrane, it has as pores for transport (nuclear pore ) sometimes the membrane continues with the endoplasmic reticulum
What is the name of the fluid that fills the nucleus what does its contain
Nucleoplasm it contains free DNA and RNA nucleotides
What is contained in the nucleoplasm and what does this contain
chromatin material it consists chromosomes made up of of DNA DNA contains the genetic material of the cell
Chromosomes are fpulded ans pcaked tighlty to form waht
Chromatin network Which is long unwound threads of genetic material found in the cell nucleus
NUCLEUS What is the function of the nuclear pore
its allows connection with the cytoplasm To allow certain substances in and out if the nucleus
NUCLEUS What is made in the nucleolus describe the structure of the nucleolus
ribosomal RNA the nucleolus has no membrane surrounding it
ENDOPLASMIC RETICULUM what is the function of endoplasmic reticulum and hers is it found
function- facilities the transport of large molecules within the cytoplasm it is found on the nuclear membrane
where is the nucleolus found and what does it function
found in the nucleus in the nucleoplasm its stores and makes ribosomal RNA it has no membrane
what is the function of mitochondria
fro cellular respiration to take place
MITOCHONDRIA during cellular respiration what is sued and what are the products
oxygen is used to break down organic substances (glucose ) to release energy the products of respiration is CO2 and water
STRUCTURE OF MITOCHONDRIA how many membranes does it have and what do they function as what surrounds the inner membrane and what is its function
2 membranes outer membrane is sooth and controls the movement of substances in and out of organelle inner membrane is folded and its is called the cristae there are granules on the folds of the inner membrane these granules contain enzymes that catalyse the reactions of cellular respiration a fluid called matrix surrounds the inner membrane it contains enzymes for respiration
STRUCTURE OF THE ENDOPLASMIC RETICULUM What does it consist of What deos the rough ER have attached to it and what does its function as What does the smooth ER function as
consists of double membranes that fold and form channels through the cell. Rough endoplasmic reticulum has ribosomes attached to the membranes which manufactures proteins. Smooth endoplasmic reticulum does not have ribosomes. It manufactures lipids and other substances.
Therefore the function of ER is to ?
Function of endoplasmic reticulum is that it makes, stores and transports carbohydrates, lipids and proteins in the cell.
where are ribosomes found
they are small granules found in the cytoplasm and some are found attached to the endoplasmic reticulum
what do each ribose consist of
they each consist of two subunits these subunits come together when s ribosome is active
what is the function of ribosome
site of protein synthesis (make new proteins) those found in cytoplasm produce protein need in cytoplasm these that are attached to endoplasmic reticulum produce proteins tat form part of membrane or are secreted from the cell
