What is the functions of these organelles?

Answer 1

You don't specify which organelles, but I'll give you the basic ones...

The nucleus contains and produces the genetic material, DNA. It has the chromosomes, and that's basically where mitosis (cell division) starts. It also conducts the activities of the cell... It's often called the "brain" of the cell. Among the codes in its DNA are the codes to produce the subsequent organelles.

Endoplasmic Reticulum synthesizes materials. There are two kinds:

• Rough ER which is covered in ribosomes that give it its rough appearance synthesize proteins. Then it packages the proteins and sends them through vesicles to the Golgi body.
• Smooth ER does the same as Rough ER, but instead of synthesizing proteins, it is in charge of lipids (fats)

The Golgi body or Golgi apparatus is the packaging center for the cell. It packages materials in the cell through vesicles by passing the materials through it and encasing them in a membrane. It sends things within the cell and even to the outside of the cell.

Vesicles are basically little bags made of membranes kind of like the cell membrane to carry materials in and out of the cell, as well as carry things from one organelle to another.

Lysosomes are a special kind of vesicle. They contain digestive juices. Lysosomes go around the cell to find over-used organelles and phagocytizes (basically swallow the dead organelle) and digest it. When the cell itself is old, the lysosome must burst, causing the digestive juices to leak and eat the cell from the inside out.

Mitochondria are the powerhouse of the cell. Through cellular respiration and fermentation, mitochondria use glucose to create energy for the cell in the form of ATP.

Ribosomes are basically the smallest organelle in the cell. It is a bonding site for mRNA and tRNA during translation. Ribosomes are where proteins are made. mRNA travels to ribosomes after transcription.

vacuoles are basically like vesicles. in humans, it's essentially the same thing, but plants have a central vacuole that aids in keeping the cell rigid.

peroxisomes are a minor organelle. because some of the body's process involves making peroxide through basic body functions. Peroxisomes help clear the peroxide, which is toxic to the body, and breaks them via hydrolysis into water and...something else...

Plants have chloroplasts that help during photosynthesis. They convert light and water energy into glucose energy, which the plant needs.
