VEGETAL CELL

PARTS OF THE VEGETAL CELL

Cell Wall
A rigid layer that supports and protects the plant cell.
Cytoplasm
A jelly like substance that contains many chemicals to keep the cell functioning.
Nucleus
The organelle that determines all of a plant cell´s activities and the production of new cells.
Cell Membrane
A covering that holds the plant cell together and separates it from its surroundings.
Vacoule
An organelle that stores food, water or wastes.
Chloroplast
organelles that make food for the plant cell.
Chromosomes
threadlike structure that contain information about the characteristics of the plant.
Mitochondria
organelles that release energy from food.

THE MICROSCOPE

A little bit of history
The first microscopes were invented in the early 1600s. One scientist who built and used an early microscope was Robert Hooke. In 1665 Hooke observed a thin slice of cork through a microscope. The tiny walled spaces he saw in the cork reminded him of tiny rooms. So he called them cells. Over the next 200 years, scientists learn more and more about the cells. They learn that the cell is the basic unit of structure and function of all living things.

CELL ESTRUCTURE

Cell membrane: a covering that holds the animal cell together and separates it from its surroundings. Through the membrane the cell takes substances that it needs to live and it removes the ones it doesn’t need.

Cytoplasm: a jellylike substance that contains many chemicals to keep the cell functioning. Its responsible for the breathing, it produces proteins and sugars, transform nutrients, etc.

Nucleus: the organelle that determinates all of an animal cell´s activities and the production of new cells. This is the place where all the genetic information is located, it´s like a huge library.

Mitochondria: organelles that release energy from food.

The cell division is essential for life, because it allows to create a similar cell. Unicellular organism, like bacteria creates other bacteria. The pluricellulars organism are duplicating at all times. Not all cells duplicate at the same speed. For example the skin cells duplicate every day to substitute the dead ones, but the neurons can’t reproduce, when they die it´s not possible to create new ones.Plants and animals are different.

The most important difference it´s that plants make their own food and animals have to go and get it. The cells of plants and animals are also different. Vegetal cells have chloroplast in the cytoplasm; there is where the photosynthesis takes place.The size and the function of the cells are related.
