-vacule
-chloroplasts
Cells were first discovered by Robert Hooke, an English scientist, discovered cells in 1665. He discovered them when he looked at a thin slice of cork with his microscope.
Most of the cell components which animals have, are also in plant cells. However, plants cells have some components which animal cells don't have.
ANIMAL CELL
Nucleus - Controls the cell and has genetic information which is used to make more cells.
Cell membrane - Controls what goes in and out of the cell.
Cytoplasm - This is where chemical reactions take place.
Mitochondria- This is where respiration happens (they use glucose and oxygen).
Ribosomes - They make proteins.
PLANT CELL
Nucleus - Controls the cell and has genetic information which is used to make more cells.
Cell membrane - Controls what goes in and out of the cell.
cytoplasm- This is where chemical reactions take place.
Mitochondria- This is where respiration happens (they use glucose and oxygen).
Ribosomes - They make proteins.
Vacule - Contains cell cap (it makes the cell more ridgid).
Cell wall - makes the cell more strong and tough (it's made out of cellulose, a tough fiber).
Chloroplasts - they make energy from light from the Sun (photosynthesis).
Each cell component has it's special function. Read on to find out about cell components in greater detail.
The nucleus is a very important and powerfull part of a cell. It controls the cell and stores genetic information which is needed to make new cells.
The cytoplasm is a water-like liquid where many chemical reactions take place. It fills up most of the cell.
The cell membrane is a thin wall that surrounds each cell. It controls what goes in and what goes out of the cell.
Mitochondria (singular is mitochondrion) float throughout the cell and create energy. They digest nutrients and then break them up.
Ribosomes are small cell components and they make proteins. Proteins are very important for cells.
The vacule is similar to a bag. The vacule contains cell cap and together they make the cell more tight and ridgid.They are only found in plant cells. If a plant wilts (droops down) it's because the vacule doesn't have much water in it and it got empty - he plant cells are not firm anymore so the plant wilts.
There are many different types of cells. Here are just a few.
There are many different types of cells. Cells which have specific functions are called specialized cells. Read on to discover different cells
Skin cells protect animals and humans from bacteria, heat and viruses. Every minute, we shed around 35, 000 dead skin cells!
Red blood cells carry oxygen and carbon dioxide around your body. They have no nucleus to increase the amount of o2 and co2 they can carry. They also don't have any mitochondria.
Nerve cells (neurons) transport messages around our body. Nerve cells also help us feel (pain, etc). They have connections on both sides of them to connect themselves to other nerve cells.
Muscle tissue is made of muscle cells. Muscle cells are flexible beacause they need to contract and expand all the time.
Sperm cells carry genetic information and have a tail for swimming in liquid. They have lots of mitochondria and a streamlined head.
Leaf cells which are at the top of the leaf have chloroplasts. Chloroplasts contain chlorophyl. unlike animal cells, leaf cells have a brick-like shape so that they can fit together.
As the name suggests, root hair cells grow on roots. They are thin and have a wide surface. They provide water and minerals to themselves and the rest of the plant by osmosis.
