What are the 3 basic structures of a 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 7 functions of the cell?
- Structure and Support. You know a house is made of bricks. …
- Growth. In complex organisms such as humans, the tissues grow by simple multiplication of cells. …
- Transport. …

What are the two cell types and their functions?
There are two main types of cells, prokaryotic and eukaryotic. Prokaryotes are cells that do not have membrane bound nuclei, whereas eukaryotes do. The rest of our discussion will strictly be on eukaryotes. Think about what a factory needs in order to function effectively.
What are the 3 major cell types and their functions?
The three major types of cells in the blood are red blood cells, white blood cells, and platelets. Red blood cells determine blood type and are responsible for transporting oxygen. White blood cells are immune system cells that destroy pathogens and provide immunity.
What are the 3 main functions of a cell?
The generalized cell functions include movement of substances across the cell membrane, cell division to make new cells, and protein synthesis.
What are the 17 organelles in a cell?
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.
What is a lysosome?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.
What are the 13 organelles and their function?
- Nucleus – stores genetic information.
- Ribosomes – makes protein.
- Plasma membrane – separates the cell from the environment.
- Endoplasmic reticulum – makes proteins and lipids.
- Golgi apparatus – sorts proteins.
- Lysosome – breaks down unwanted material.
What are the 2 main types of body cells?
What Kind of Cells Make Up Your Body? Life on earth is classified among two major classes of cells. These cells are eukaryotic cells, and prokaryotic cells. Humans and most complex multicellular organisms are classified as eukaryotes, which means they are made up of eukaryotic cells.
What are the two 2 kinds of cells?
There are two distinct types of cells: prokaryotic cells and eukaryotic cells. Though the structures of prokaryotic and eukaryotic cells differ (see prokaryote, eukaryote), their molecular compositions and activities are very similar.
Who invented cell?
The cell was first discovered and named by ROBERT HOOKE in 1665.
What is the biggest cell in a human body?
Ovum (female gamete) is the largest cell present in the human body. It is a single cell released from the ovary every month. The size of each ovum is 0.1mm in diameter.
What are the 6 major cell types?
- Stem cells. Stem cells are cells that must choose what they are going to become. …
- Bone cells.
- Blood cells. There are many types of blood cells, including:
- Muscle cells. Also called myocytes, muscle cells are long, tubular cells. …
- Sperm cells. …
- Female egg cell. …
- Fat cells. …
- Nerve cells.
Why are cells so small?
Cells are so small because they are easier to replace, and a cell needs to be small to be able to perform the tasks a cell needs to do. If cells were bigger it would be harder for the body to replace the cell without disrupting what is going on in the body and delaying a process.
What are the 8 main functions of a cell?
- A cell performs various activities, which are important for the development and growth of an organism. …
- It facilitates growth during mitosis.
- It provides structure and support.
- It helps in the generation of energy.
- It permits the transport of different substances.
- It helps in the process of reproduction.
What are the 7 functions of the cell wall Class 9?
- It provides protection to the cell and prevents from any physical damage.
- It provides structure to the cell.
- It prevents from osmotic bursting.
- It protects the protoplasm against mechanical injury.
- It controls intercellular transport.
What are the 11 functions of a cell?
Cells must perform 11 main functions in order to support and maintain life: absorption, digestion, respiration, biosynthesis, excretion, egestion, secretion, movement, irritably, homeostasis, and reproduction.
What are 5 life functions of cells?
All organisms can perform the five basic life functions: use energy, grow and develop, dispose of waste, respond to the environment, and reproduce.
