Organisation maintenance of the organism
Introduction
Cells
Cells are the basic building blocks of all living things
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Cell organelles
Cytoplasm
A thick solution that fills each cell and is enclosed by the cell membrane
It is mainly composed of water, salts, and proteins
The cytoplasm includes all of the material inside the cell and outside of the nucleus.
Nucleus
A membrane-enclosed organelle within a cell that contains the genetic data
it facilitate its transcription and replication.
It controls cell activities
Mitochondria
Mitochondria are membrane-bound cell organelle that generates most of the chemical energy needed to power the cell's biochemical reaction
Cell Wall
Itprovides a structural framework to support plant growth and acts as the first line of defense when the plant encounters pathogens
A rigid wall that, prevents the cell from rupturing
Cell membrane
Controls what goes in and out of the cell
Endoplasmic Reticulum
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Specialized cells
Specialised cells are cells designed to carry out a particular role in the body
examples
Red blood cells
Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
Cillia cells
propelling mucus up the airway, thereby removing particulate material.
nerve cells
The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).
Root hair cells
The root hairs are where most water absorption happens. They are long and thin so they can penetrate between soil particles and they have a large surface area for absorption of water. Water passes from the soil water to the root hair cell's cytoplasm by osmosis .
Tissues
a group of cell are called as tissues. Each tissue has is own function
There are four main types of tissues in animals
connective tissue, epithelial tissue, muscle tissue, and nervous tissue and blood.
