Cell Project
There are 2 kinds of cells, Animal, and Plant...
- 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
