Cell Project

There are 2 kinds of cells, Animal, and Plant...

Cells have many parts...

  • The cell membrane is like the skin of the cell, and helps control movement of substances like nutrients in and out of the cell

Cytoplasm is a jellylike substance that takes up most of the space inside the cell, and distributes oxygen and other materials

  • The nucleus controls the cell, it's a small, dark, round object. The nucleus contains chromosomes, which help the cell grow and reproduce
  • Vacuoles are the storage spots of the cell, containing things like waste, food, and other substances
  • The cell wall is an organelle specific to plant cells, and provide support for the cell
  • Chloroplasts are another organelle that is only found in plant cells. They use photosynthesis to create food for the plant cell
  • Mitochindria is the name of the organelle that acts as the "kitchen" of the cell, making the food the cell takes in useful for the cell

Plant and animal cells have several differences between them, like shape, plant cells are a square-like shape, while animal cells can be almost any shape, also the plant cell has several organelles not found in animal cells...

Shape can matter in a cell because it can effect how the cell can function...

...Plant cells, with their generally square shape, can only perform one task, making sugars for the plant with photosynthesis and giving support to the plant.

Whereas animal cells can be any shape, allowing them to perform specialised tasks, like muscle cells, for example, but can be anything from blood cells to nerve cells

One last thing that makes a plant cell different is

that they can make their own food, while animal cells cannot...

Many materials go in and out of cells, like food and water, through the processes of diffusion and osmosis...

DIFFUSION

Diffusion is when objects move from

places of higher concentration to places

of lower concentration. Cells can use

this process to take in stuff like nutrients

or remove wastes from the cell...

OSMOSIS

Osmosis is like Diffusion, except it only happens with water

Cells are about 70 percent water, and to survive

they need to maintain that...

When water moves out of a cell, the substances inside become a

higher concentration.

When the cell takes in water, it dillutes the substances

inside the cell, and makes it lower concentration causing more

water to enter the cell because there is a higher concentration

outside the cell than inside the cell.

Osmosis can only happen through selectively permeable

substances
