Biology Word List

The cell is one of the most basic units of life.

The cell membrane regulates the movement of water, nutrients and wastes into and out of the cell.

The cell nucleus contains the cell's DNA, the genetic code that coordinates protein synthesis.

Specialized pigments in the chloroplast (including the common green pigment chlorophyll) absorb sunlight and use this energy to complete the chemical reaction:

6 CO2 + 6 H2O + energy (from sunlight) C6H12O6 + 6 O2

In this way, plant cells manufacture glucose and other carbohydrates that they can store for later use.

The cell nucleus contains the cell's DNA, the genetic code that coordinates protein synthesis.

Lysosomes are organelles that contain enzymes that aid in the digestion of nutrient molecules and other materials.

In addition to the nucleus, there are many organelles inside of the cell - small structures that help carry out the day-to-day operations of the cell.

The cell nucleus contains the cell's DNA, the genetic code that coordinates protein synthesis.

Many animals have skeletons to give their body structure and support.

And there are cells that only function when part of a larger organism, such as the cells that make up your body.

Below is a labelled diagram of a cell to help you identify some of these structures.

And all have some recognizable similarities.

Specialized pigments in the chloroplast (including the common green pigment chlorophyll) absorb sunlight and use this energy to complete the chemical reaction:

6 CO2 + 6 H2O + energy (from sunlight) C6H12O6 + 6 O2

In this way, plant cells manufacture glucose and other carbohydrates that they can store for later use.

Mitochondria (many mitochondrion) are often referred to as the power plants of the cell because many of the reactions that produce energy take place in mitochondria.

All of these cells have unique functions and features.

Ribosomes participate in protein synthesis.

The cell membrane regulates the movement of water, nutrients and wastes into and out of the cell.

The cell wall is a rigid structure outside of the cell membrane composed mainly of the polysaccharide cellulose.

Mitochondria (many mitochondrion) are often referred to as the power plants of the cell because many of the reactions that produce energy take place in mitochondria.

Below is a labelled diagram of a cell to help you identify some of these structures.

As pictured at left, the cell wall gives the plant cell a defined shape which helps support individual parts of plants.

After this step is complete, the mRNA leaves the nucleus and travels to the cell's ribosomes, where translation occurs.

The transcription phase of protein synthesis takes places in the cell nucleus.

The cell wall is a rigid structure outside of the cell membrane composed mainly of the polysaccharide cellulose.

The chloroplast allow plants to harvest energy from sunlight.

Specialized pigments in the chloroplast (including the common green pigment chlorophyll) absorb sunlight and use this energy to complete the chemical reaction:

6 CO2 + 6 H2O + energy (from sunlight) C6H12O6 + 6 O2

In this way, plant cells manufacture glucose and other carbohydrates that they can store for later use.

Many animals have skeletons to give their body structure and support.

The cell nucleus contains the cell's DNA, the genetic code that coordinates protein synthesis.

In the next lesson, we will examine how individual cells come together to form larger structures in the human body.

All cells have a 'skin', called the plasma membrane, protecting it from the outside environment.

Organisms contain many different types of cells that perform many different functions.

As pictured at left, the cell wall gives the plant cell a defined shape which helps support individual parts of plants.

All of these cells have unique functions and features.

After this step is complete, the mRNA leaves the nucleus and travels to the cell's ribosomes, where translation occurs.

While both plant and animal cells contain the structures discussed above, plant cells have some additional specialized structures.

Specialized pigments in the chloroplast (including the common green pigment chlorophyll) absorb sunlight and use this energy to complete the chemical reaction:

6 CO2 + 6 H2O + energy (from sunlight) C6H12O6 + 6 O2

In this way, plant cells manufacture glucose and other carbohydrates that they can store for later use.

One major difference in cells occurs between plant cells and animal cells.

In the body, there are brain cells, skin cells, liver cells, stomach cells, and the list goes on.

At the center of the cell is the cell nucleus.

Lysosomes are organelles that contain enzymes that aid in the digestion of nutrient molecules and other materials.
