Answers
Answer:
Within the cytoplasm, the major organelles and cellular structures include: (1) nucleolus (2) nucleus (3) ribosome (4) vesicle (5) rough endoplasmic reticulum (6) Golgi apparatus (7) cytoskeleton (8) smooth endoplasmic reticulum (9) mitochondria (10) vacuole (11) cytosol (12) lysosome (13) centriole.
Nucleus - it is the master/control house of the cell. It is a small , round and membrane bound structure found in cell. The fluid inside the Nucleus is surrounded by nuclear membrane called nucleoplasm.
Ribosome-these are membrane less organelles in the cell. These are the protein factories of the cell. They are special organelles as they are found in both prokaryotic and eukaryotic animals.
Endoplasmic reticulum - the large network of membranous sheets and tubes is known as ER.
They are filled with fluid and carries material throughout the cell due to which it is also called transport system of the cell. It is of two types - RER(rough Endoplasmic reticulum) and SER ( smooth Endoplasmic reticulum).
Golgi apparatus - the stacks of flattened membranous vesicles are known as golgi apparatus. It temporarily stores protein that moves out through the cell by vesicles of golgi apparatus. It helps in the formation of lysosomes.
Chloroplast - it absorb light energy and convert it to into chemical energy. It contains chlorophyll which functions by trapping solar energy and use for synthesis of food in all green plants.
Mitochondria - they are known as the power house of the cell because they produce energy in the form of ATP which is needed for various chemical reactions needed for life. It contain its own genetic material.
