What are the 7 functions of a cell?
Answer. Answer: movement, reproduction, response to external stimuli, nutrition, excretion, respiration and growth.
What is the basic structure of cell?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
What are the function of each organelles?
Organelles and their Functions
| Organelle | Cell Type | Function |
|---|---|---|
| Mitochondria | Eukaryotic | Makes energy |
| Lysosome | Eukaryotic, animal cells only | Removes unwanted material and waste |
| Peroxisome | Eukaryotic | Regulate biochemical pathways that involve oxidation |
| Vacuoles | Eukaryotic | Store water and nutrients |
What is the function of all the organelles?
Organelles are small structures within the cytoplasm that carry out functions necessary to maintain homeostasis in the cell. They are involved in many processes, for example energy production, building proteins and secretions, destroying toxins, and responding to external signals.
What is the function of each organelle?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
Which is a list of organelles?
Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells.
What are the 8 functions of cells?

What are the 4 types of cells?
The Four Main Types of Cells
- Epithelial Cells. These cells are tightly attached to one another.
- Nerve Cells. These cells are specialized for communication.
- Muscle Cells. These cells are specialized for contraction.
- Connective Tissue Cells.
What is the smallest cell?
Mycoplasma
Mycoplasma or PPLO (Pleuropneumonia like organism) is the smallest cell.
What are the 8 types of organelles?
Different Cell Organelles and their Functions
- Plasma Membrane.
- Nucleus/DNA.
- Ribosome.
- Mitochondria.
- Vacuoles.
- Cytoskeleton.
- Plastids.
- Endoplasmic Reticulum.
What is the function of cytoplasm?
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
How many types of organelles are there?
6 Cell Organelles
- Nucleus. Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid).
- Ribosomes. Ribosomes are the protein factories of the cell.
- Endoplasmic reticulum. Encyclopædia Britannica, Inc.
- Golgi apparatus.
- Chloroplasts.
- Mitochondria.
What is the structure and function of the cell membrane?
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
What are the functions of each organelle?
What is the most important organelle?
Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
Who discovered cell?
Robert Hooke
Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.
Which is longest cell?
neuron
The longest cell of the body is the neuron. The axon of the neuron forms the nerve fibre and extends throughout the length of the body from the ganglia.
Which is biggest cell?
The human egg (ovum) is the largest cell in the body and can be seen without the aid of a microscope. It is one millimeter in diameter. Whereas, a nerve cell is the longest cell in human body. Was this answer helpful?
What is organelle explain?
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
What is the function of lysosomes?
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.
What is the function of a chloroplast?
Chloroplasts are the place for the major conversion of the sun’s radiation energy to chemical energy that is usable by organisms. Accordingly, they account for about 50% of the leaf protein [1], and the enzyme ribulose-1,5-bisphosphate carboxylase of chloroplast is by far the most abundant protein on the Earth [2].
